According to his own account, Ivo Robotnik's villainy began when he was a child, when he captured his nanny and became dictator of the nursery. Growing up, he was depicted as a fairly typical bully, and was plotting world domination as early as High School. Though he was expelled from High School for unspecified reasons (though it is implied terrorizing his classmates contributed to this), Robotnik did attend higher learning, and graduated as a certified genius alongside fellow evil mastermind John Paul Memo. At some point afterwards, Robotnik lost patience with the eccentricies of his cousin, the derranged Dr. Warpnik, and exiled him to the mysterious Warp of Confusion. Eventually Robotnik built his fortress on top of one of Mobius' biggest mountains, where he would plot many of his schemes to conquer the planet.
- Sonic the Hedgehog (TV Series)
Robotnik was originally named Julian. He once worked as an assistant for Naugus, a wizard who discovered a limited dimension known as the Void. Julian betrayed Naugus and trapped him within the Void, but continues to dread the possibility of Naugus getting loose.
Julian later headed up the Ministry of War in the King's regime, and was instrumental in winning the Great War for the monarchy. The King allowed Julian to dismantle the military — from his perspective, this was because the War's end no longer necessitated it, while Julian's motive was to set up a coup. Julian stole the plans for the Roboticizer from Sonic's uncle, Sir Charles Hedgehog, who originally had positive intents for the device.
Robotnik's left arm was replaced with a robotic substitute when Sonic knocked him off-balance during an early encounter (his arm getting caught in a roboticizer as he tried to steady himself).
- Sonic Underground
Dr. Robotnik began his rule by seizing the great city of Mobotropolis from the current monarch, Queen Aleena, and had it converted into his capital city: Robotropolis. After a bounty was placed on the newborn children of the queen, she was forced to go into hiding. Meanwhile, Dr. Robotnik roboticized each citizen but keep the wealthy around to help fund his polluted factories. Queen Aleena was forced to separate with her offspring after hearing a prophesy from the Oracle of Delphius. Dr. Robotnik would have each of the children’s caretakers (Chuck, Lady Windermere and Ferrell) captured and roboticized. Yet resistance was met in the form of the queen’s children, who were now grown. Sonic the Hedgehog, Sonia, and Manic, now part of a musical band would grow to be the biggest enemy in Dr. Robotnik’s rule since he came into power.

Dr. Eggman was born on Earth but under unknown circumstances, he was transported to Sonic's world. During his life, he had attempted numerous times to carry out his ambitions for achieving world domination but was thwarted by the heroic efforts of Sonic the Hedgehog and his friends.
- Sonic Boom (Series)
Eggman's childhood is implied to have been rough. According to himself, he wanted at first to become a traffic cop, but had to give up that dream. Supposedly, he also had issues with his mother and reportedly made some desperate attempts to earn the approval of his oppressive father. The first robot he ever made was one he called Zippie. He would eventually attend evil scientist school, though he was bullied by vicious girls while in middle school. At some point, Eggman was also a member of his own improve troupe named the Gigglesnorts.
Dr. Eggman discovered the ancient Destruction Troops, whose technology far surpassed his own, and seized them for himself. Identifying their creator as Lyric the Last Ancient, Eggman planned to free Lyric from his imprisonment in his tomb to get the secrets to his technology and become more powerful.
Learning that only Sonic could open Lyric's Tomb, Eggman planned to have him release Lyric for him. Eggman thus staged a scheme that made Team Sonic chase after him in his Eggmobile to the tomb, during which he had Metal Sonic come to his aid to help content with the heroes. Near the tomb, Eggman sicced his Destruction Troops on the heroes, and watched from the sidelines as his troops and Metal Sonic forced Team Sonic into Lyric's Tomb where they accidentally freed Lyric, just as Eggman had planned.
Eggman soon found Lyric in the Abandoned Research Facility and tried subjugating him with his own Destruction Troops. To Eggman's surprise though, Lyric easily retook control over his robots, so Eggman instead offer a partnership. With Lyric having trouble with Sonic spoiling his plans for world destruction, Eggman was allowed to aid, though their partnership was nothing but uneasy. Eggman was thus sent out to stop Team Sonic and reclaim a map for the Chaos Crystals that they had stolen, but failed both tasks, although Lyric let it pass as he had anticipated his failure. The two soon tracked down Team Sonic and their Crystals, but Eggman bumbling made them lose them. While they agreed to dissolve their partnership, Eggman summoned Metal Sonic to destroy Lyric, only for Lyric to take control of Metal and had him launch Eggman away. Building the control-immune Eggman Mech and finding the Twilight Crystal, Eggman returned to overthrow Lyric, but his mech proved inadequate to fight the rogue Ancient who casually left. Eggman thus turned his frustration towards the mocking Team Sonic, but the team destroyed his mech and Eggman had to flee.
With the Eggman Mech barely functional, Eggman came to Lyric's Lair as Team Sonic fought Lyric, where he fired a missile at Lyric as he prepared to finish the heroes off. Though the effort made his mech collapse, Eggman saved Team Sonic and allowed the team to defeat Lyric for good. Not long after, Eggman found Lyric's technopathy device which had been removed by Sonic, and incorporated it into his wrist controller, laughing manically over his future plans.
Eggman sent Metal Sonic after Team Sonic. When the robot found the group in Ancient Ruins, Eggman appeared on a computer screen and ordered Metal Sonic to attack the heroes, which the robot failed at.
Eggman had discovered a powerful element called Ragnium, which he started mining to use as fuel for his henchbots in an attempt to humiliate Sonic by making them faster than him, damaging the environment in the process. Needing a robot to mine the Ragnium, Eggman created D-Fekt. Upon activating him however, D-Fekt malfunctioned and began using his defective magnetic powers to build himself up to defeat Sonic.
- Adventures of Sonic the Hedgehog
Robotnik is shown through the series to be a sinister and sadistic man, who enjoys the pain and suffering of the planet. His plans often involve either the destruction of Sonic, or the destruction of an entire city while Sonic is incapacitated. He is the brain behind the majority of the plots in the show, and is exceptionally vain in both his ideas and appearance. Robotnik is openly obsessed with eggs, being the only thing he will usually eat, as well as incorporating egg-themes into many of his inventions.
Robotnik is often the one to spot Sonic's disguises, although he gets fooled as well. The majority of his traps fail due to either his execution, the machine itself failing, or Scratch and Grounder botching the plan. Despite these and many other, he has allegedly conquered most of the planet (or at least he claims to), and is depicted as being quite rich due to both patents and pilfering the citizens of Mobius.
In the series he has two known relatives, and one built himself. Doctor Warpnik, his crazy cousin, was banished to the Warp of Confusion for being insane. Mama Robotnik, Robotnik's mother, recurs several times, and is the only force Robotnik respects and fears. Robotnik Jr., the son he built himself to carry on his legacy, switched sides to Sonic when he realized his father was crazy. He also makes an alliance at one point with Dr. Qwark, a rival mad genius who also wants to destroy Mobius, however the alliance is short lived as neither can agree on who is to blame when things go wrong. Captain Memo also makes an alliance with Robotnik at one point after a violent misunderstanding due to Sonic, however Robotnik abandons him to the mercy of the Merhogs when the plans go sour.
- Sonic the Hedgehog (TV Series)
Robotnik is cruel, sadistic, cantankerous, ruthless, and egotistical. He has a relatively short temper and is often brash and overconfident with his designs. A personal grudge he holds against Sonic frequently clouds his better judgment. This is shown when he took the chance to fire a missile at Sonic even though his escape pod was short on fuel and if he fired the missile, he would crash (but the missile didn't fire because of damaged circuitry). However, he was still very a repulsive character, and was not above lying, backstabbing and murdering to accomplish his goals.
He has also tried to roboticize Sonic to be his slave several times, but this has often failed. However, he later admitted that he considered Sonic to be "a most worthy adversary" and that he was "almost sorry that it's over".
- Sonic Underground
He is mean and cruel. He loves being evil and doesn't care about anyone. He wants people to suffer and will stop at nothing to make his plans succeed. However he does mistreat Sleet and Dingo for their failures. Robotnik also turns people into slaves such as some that aren't royalty and some that are.
- Sonic X (Anime)
Despite having a few evil moments in the series, this version of Eggman is considerably more lucid and overall sympathetic than most other community. Clearly not having problems with kidnapping and threatening to inflict harm, he does, however, think it to go too far by actually hurting his hostages and dislikes to harm humans and animals alike; for example, when the Metarex begin to beat up a captive Chris and Cosmo, Eggman criticized them for their malicious behavior towards the two. Earlier in the series, when the Eggsterminator was brutally beating Sonic, Eggman could not bear to watch and even ordered the robot to stop and give Sonic a break.
In contrast, he seems more flamboyant than most of his other counterparts, as he is frequently seen showing off, although he retains some of his normal version's personality, such as his immaturity. He also appears to be a fan of baseball, as seen in Unfair Ball, where he makes the main characters play a baseball game against him and his team for a Chaos Emerald.
- Sonic Boom (Series)
Dr. Eggman is a short-tempered, ego maniacal, raucous and pompous evil mastermind. He has all the qualities of a classic villain: he looks, talks, and dresses like a bad guy and has selfish and unmotivated dreams of conquering the world, the destruction of his enemies or both. A would-be tyrant, he has a hunger for power and desires as well attention, adulation and a little respect. He holds a high view on himself which makes him arrogant to such a degree that he denies his past failures and finds his terrible actions justified. Driving by a constant desire to ultimately enslave the entire world, he is determined to do whatever it takes to achieve his goals, even if that means causing meaningless destruction, getting into otherwise awkward situations or joining an enemy more powerful than he is. His uncaring personality is mostly due to his over-inflated ego, as he only views himself with utmost pride.
Matching his arrogance, Eggman is rather vain. He is very concerned with how he and his robots look like and takes great pride in his mustache, which he grooms professionally and would give up his chance at power to preserve. Despite having unlimited resources at his disposal, Eggman can be rather stingy as he refuses wasting more money than needed and always complains when he thinks his money are going down the drain. While sometimes showing the tendencies of a neat-freak, Eggman actually has poor personal hygiene.
Eggman is a complicated guy when it comes to his relationships. While contradictory to his previous villainous exploits against them, Eggman has no trouble cutting loose and having fun with his enemies at appropriate times, whom he can even show a sincere fondness of. In the case of Amy, he remains her enemy on the battlefield, but in their free time they are "Fuzzy Puppy buddies." Though this comradely behavior is sometimes a front to exploit his enemies, Eggman is willing to provide genuine help to his enemies as he believes the "bro code triumphs the enemy code".
In spite of his smarts, Eggman is deranged, immature and buffoonish in behavior, and his schemes are usually more zany rather than threatening. While his pride and arrogance are his core parts, they are also his greatest weakness, as they make him far too overconfident and a blabbermouth which ultimately leads to his downfall. Excessively self-deluded, he thinks others secretly admire him and only mock him out of jealously. When in situations over his head though, he is willing to abandon his pride to get help, even if it means demeaning himself. He is also laidback and is noted to be somewhat of a doofus as he misses out on great opportunities to eliminate Team Sonic, and he can pretty much only handle situations in a villainous manner.
Because of all his flaws, no one really considers him a true bad guy; however, this also works in Eggman's favor as people tends to underestimate him, which makes him an unpredictable opponent. Eccentrics aside, Eggman is still a highly intelligent and manipulative individual under the right circumstances who can play his foes right into his hands. Also, while things might not always work out for him initially, he is always working behind the scenes to get the upper hand and come out on top.
- Adventures of Sonic the Hedgehog
He has a curve head and a orange mustache. He also has a red nose. He wears gray gloves and has a chubby stomach. He has a red suit that has a round yellow belt. He also has red boots. He has black eyes with red pupils.
- Sonic the Hedgehog (TV Series)
Robotnik is a tall human man of imposing girth with a bald, conical head, a dark orange mustache and black eyes with crimson irises. Robotnik is also partially roboticized, resulting in his left arm from the shoulder and down to be completely robotic. In the place of his ears, he had small metal stubs. Strangely enough, in the episode "Sonic Conversion", the doctor is shown to have five uvulas and a hairy tongue.
His usual attire is a jumpsuit, red above the waist and black below, with yellow lines spanning up, down and around his body; grey leggings; black-and-red boots; wide, red shoulder pads; a black sleeve on his human arm; a yellow cape; and grey gloves.
While Minister of War for Mobotropolis, prior to his coup (before he was partially roboticized), Julian wore a white militaristic uniform with blue chains across the front, black-and-red epaulets, medals on the left side of his breast and a bearskin hat.
- Sonic Underground
Robotnik has many different design changes. First off, he has a longer and more colored mustache then in the normal games. He also has a roboticized arm after an incident that happened to him in the Underground. He wears a long belt going around his waist. His boots are shorter and more colorful. Finally, he sports a cape, supported by big, heavy yellow shoulder pads. Dr. Robotnik was modified specifically to look like he were a mechanic.
- Sonic X (Anime)
He has a round head and wears gray goggles on top of his head. He wears sunglasses on his eyes and has white gloves. He wears a red suit and has a red mustache. He has a pink nose and wears gray pants. His suit has a white zipper while it also had yellow pocket on it. The bottom sleeves are also yellow.
- Sonic Boom (Series)
Unlike his main series counterpart, who is more round around the stomach, Dr. Eggman's torso is more round at the top, and he has more smooth, yet still broad shoulder. His mustache is also shorter and smoother, and a bit darker, and his legs are slightly shorter with significantly smaller feet.
Eggman's usual attire consists of militaristic garments. He wears a red jacket with yellow cuff, a front flap attached to one of the buttons and two flap hanging from the back, blue pince-nez glasses, white gloves, a set of grey goggles with flappable green lenses, grey pants and a pair of black boots with high rims. On his right wrist he has his wrist controller.
For sleeping or otherwise slouching, Eggman wears a pink pajamas with feet, with the Eggman Industries's symbol on the front and a trapdoor on the rear. Other attires he has worn include an overcoat, a red fitness vest and a diving suit. During the Eggtoberfest, Eggman also wore green lederhosen with a yellow shirt, white shocks, brown shoes, and a brown fedora with a red feather.
The episode begins with Sonic and Tails being captured by Scratch and Grounder. While hanging upside down in a tree, Sonic decides to remind Scratch and Grounder how they all first met.
In a flashback, there is a gathering of Badnik bounty hunters. Dr. Robotnik called this group together to offer them an award of a billion Mobiums for Sonic alive or otherwise. Sonic is in the audience, but it takes everyone a long time to realize it. Robotnik eventually sicks all the robots on him. Sonic runs out and tricks each robot into a path of their own destruction.
Back at his lair, Dr. Robotnik decides to make two new robots for the sole purpose of catching Sonic. He throws many ingredients into a machine including a pair of rotten eggs. As a result, the machine produces Scratch. Thinking Robotnik is his mother, Scratch begins kissing Robotnik and licking his body. Annoyed, but not taking it too seriously, Robotnik clones Scratch with his robot making machine. Scratch pulls one extra lever which was not supposed to be pulled. The machine produces Grounder and right off the bat, the two start bickering about who is Robotnik's favorite. Robotnik dubs the two robots his Super Special Sonic Search and Smash Squad.
Coconuts watches from the bathroom. Coconuts is jealous of these new robots because he had been rejected by Robotnik and put on latrine duty. He vows to catch Sonic himself and win Robotnik's love.
Sonic and Tails are out running when they find a chili dog stand which is run by Coconuts in disguise. The stand becomes a large Robot that chases the heroic duo, but is eventually defeated. Similarly Scratch and Grounder try a number of clever plots to catch Sonic. Eventually they succeed in capturing Tails, thus Sonic gives himself up to ensure Tails' safety.
With Sonic and Tails captured, Scratch and Grounder call Robotnik to come and pick them up. Coconuts sneaks up on them and ties up Scratch and Grounder so as to take credit for capturing Sonic and Tails. Sonic convinces Coconuts to put Scratch and Grounder in the cage with him. Coconuts proceeds, but sure enough when he opens the cage, Sonic escapes and traps all three Badniks in the cage. he frees Tails and creates a dust storm making Dr. Robotnik unable to see when he flies in on his Egg-o-Matic. Sonic tricks Robotnik into landing on the cage and smashing up his own henchmen.
Back in modern day, Sonic ends the story and is still hanging from the tree. Scratch and Grounder don't like the story because they don't catch Sonic in the end. Sonic escapes the tree, then he and Tails run away.
After fuming about how much he hates Sonic, Robotnik's Deluxe-Highly-Callibrated-Hedgehog-ometer picks up Sonic's presence, being in the Marble Zone. He subsequently activates a Spring that launches Scratch and Grounder there. When they arrive, the Badniks chase Sonic and Tails, but they escape down a geyser which leads to a series of tunnels. Nevertheless, Scratch and Grounder decide to follow them.
Sonic and Tails find a cave full of gold and diamonds. They also meet a mole named Spelunk who thinks they want his money. He tries to blast them with a cannonball, but they manage to avoid it. The cannonball ends up trashing Scratch and Grounder. Sonic and Tails come across minecart tracks which they assume will lead them out of the underground tunnels. They run along the tracks, but are stopped by an angry Spelunk coming straight at them in a minecart. Sonic and Tails try to outrun him when they notice a family of turtles crossing the tracks. Sonic dresses as a crossing guard and stops Spelunk, allowing the turtles to cross the track. Once the turtles are safe, Sonic lets Spelunk's minecart pass. He and Tails once again attempt to leave the tunnels.
Running up a flight of steps, Sonic and Tails have almost reached the surface. Spelunk, realizing he had been tricked by Sonic, pulls a lever which smooths out the staircase. This causes Sonic and Tails to slide back down the steps and into a cage. The bars are made from diamondius, the hardest substance on Mobius, so Sonic cannot cut through them.
Scratch and Grounder return with Dr. Robotnik in drilling vehicles which they plan to use to obtain Spelunk's loot and capture Sonic simultaneously. Angry that Robotnik is after his treasure, Spelunk blames Sonic and opens a pit in the cage where Sonic and Tails are being kept. Scratch and Grounder use dynamite to blow a hole in the ground. The cave crumbles and a large diamond breaks the cage open, freeing Sonic and Tails. Robotnik, Scratch and Grounder fall into the pit.
With the cave crumbling, Sonic decides to escape, but Spelunk doesn't want to leave his treasure behind. Sonic saves Spelunk from being crushed by a falling boulder. He is touched that Sonic saved him, so he returns the favor by leading them outside the tunnels to safety.
Robotnik, Scratch and Grounder, who have somehow escaped the pit, begin to steal Spelunk's treasure. Sonic, who is dressed like an IRS auditor, informs Scratch and Grounder of all the paperwork and taxes they have to deal with for acquiring this large amount of treasure. The initials for the taxes spell 'You are so stupid'. Sonic binds the three villains in calculator paper and sends them up a conveyor belt into Robotnik's Egg-o-Matic. Spelunk then pours gunpowder on the conveyor belt and lights it with a match. Sonic quickly removes the treasure from the Egg-o-Matic before the gunpowder explodes and sends Robotnik, Scratch and Grounder blasting off.
Spelunk says he's never met such greedy, miserly jerks before in his life, but Sonic and Tails point out that he is one himself. Spelunk thanks Sonic for showing him the error of his ways and he decides to use his fortune to buy chili dogs for Sonic and Tails.
When Sonic saves a very pretty girl hedgehog named Breezie from Scratch and Grounder, she flirts with him. Then Breezie gives Sonic a kiss and love hearts appear in Sonic's eyes. Sonic is unaware that Breezie is actually one of Robotnik's robots, sent to distract him while he proceeds to destroy the underground wells of Mobius with his new Egg-o-Matic Tunnelizer and Town Terrorizer. Meanwhile Sonic returns as all the snow melts off him. Tails lets Breezie see how tired Sonic is. So Breezie strokes Sonic's head. Then Sonic runs along to heat up Breezie's chili dog.
After Breezie throws Tails in a rushing river, Scratch and Grounder come to team up with Breezie and make plans to eleminate Sonic. Tails makes it back and spies on the three robots as they plot their traps. Tails rushes off to warn Sonic and tell him about Breezie, but Sonic is too twitterpaited to listen. After Sonic writes a romantic poem for Breezie, she starts to develop feelings for him. But it is too late, Sonic runs to the robots' big magnet. Fortunately, Breezie frees Sonic, and they escape.
Breezie tells Sonic that she is a robot and of Robotnik's plans to drain the reservoir. Sonic stops Robotnik by attaching a bungy cord to his Egg-o-Matic Tunnelizer and Town Terrorizer. Robotnik springs into the opposite direction yelling "I hate that Hedgehog!".
Sonic is sad, but Tails brings him a note from Breezie which says she hopes they'll meet again some day.
Dr. Robotnik flies to the Sloth's home planning to use them as bait to lead Sonic into a trap. He damages their house with Scratch and Grounder. Rocket the Sloth sees Robotnik escape and sends a Morse code message to Sonic for help. Back at Robotnik's fortress, the evil Doctor shows Scratch and Grounder his Subatomic Slow Go Beam Weapon which can shoot a slow motion beam that will put Sonic into sloth motion. However, his mind is still accelerated (when Sonic pulls on Scratch's tail feathers, Jaleel's grunts for Sonic were recorded at normal speed). Sadly, it doesn't last long; the effects wear off in one hour.
Sonic and Tails arrive at the Sloth's home and repair the damage caused by Dr. Robotnik. Rocket sits in a tree with a gong, on the look out for danger. Scratch and Grounder come and begin firing slow rays. Sonic figures out what the ray does. Robotnik shows up and Scratch and Grounder accidentally zap him again. Robotnik leaves for an hour. Scratch and Grounder set a trap for Sonic, by having Scratch hide in a tree while Grounder hangs from a branch disguised as a distressed Sloth. Sonic stops to help the sloth, allowing Scratch time to zap him with the slowness ray, slowing down his molecules and his voice. Sonic slowly tells Tails to go warn the sloths. Scratch and Grounder capture Sonic and take him to a cave where they put him in a cage and call Robotnik to tell him their good news.
Back at the Sloth's home, realizing Rocket can't help him, Tails goes to save Sonic himself.
Back in the cave as Scratch and Grounder taunt Sonic, Tails steals the slow ray and threatens to shoot Scratch and Grounder. Grounder knocks it out of his hands, breaking the crystal that it runs on. Tails takes the slow ray and retreats to the Sloth home.
Back at the Sloth's home, Rocket uses the slow ray to make him and his family super fast. Tails and the four speedy sloths rush off to save Sonic. The Sloths roll into balls like Sonic, they bounce around and hit Scratch and Grounder. Tails zaps Sonic with the ray and he is back to his fast self. Sonic quickly takes care of Scratch and Grounder. Robotnik comes and Tails zaps him with the ray making his Egg-O-Matic go super fast. Speeding beyond control, Robotnik crashes into a mountain.
In a town, Smiley is using underhanded techniques to gain all the material assets of a group of Gambler Sheep. Once they have nothing left to lose, Smiley takes them as slaves to work on building Dr. Robotnik a sphinx in the desert.
Smiley has a cheating robot (or High Voltage Flimflammer as Sonic calls him) who plays a game with a pea under one of three nut shells. Sonic comes to help the sheep win. Sonic's eyes are fast enough to keep on the pea and he wins every time. The Flimflammer malfunctions and blows up. Sonic wins back all the sheep's things. In order to get them back, Smiley lures the sheep to Robotnik's Casino Night Zone. The sheep, having not learned their lesson, go to the Casino Night zone and gamble until they lose everything again.
Sonic and Tails go to the Casino Night Zone where Sonic disguises at a maintenance worker and resets the machines to make the sheep win. The Sheep get a lot of money. Sonic leaves Tails in the nursery with a pig lady while he runs off to take care of Scratch and Grounder.
While Tails is playing in the Nursery ball room, the Pig Lady reveals that she works for Robotnik and has Tails fall into a trap. Robotnik puts Tails in a cage. Tails gets mad and calls Robotnik a "Crum-bum," and when Robotnik comes close, Tails ties Robotniks' mustache to the bars of his cage. Robotnik eventually gets free.
Sonic returns to Casino Night Zone and cannot find Tails. Smiley tells him Tails is captured by Robotnik and to ensure his safety Sonic has to lose a race to Grounder.
At a large Stadium, Scratch announces the race and all the sheep bet on Sonic. Sonic sadly walks in the race, disappointing all the sheep. Bragging about his imminent victory, Grounder tells Sonic that Tails is in a cage underneath the stadium. Sonic tunnels underground and saves Tails, tunnels back up and wins the race, but Robotnik has already taken the sheep as his slaves. Sonic runs to the desert and sets Louis and the sheep free. He then re-designs Robotnik's sphinx to look like himself, after which the Sphinx looks at Robotnik and winks. This upsets Robotnik, making him cry.
The sheep then ask Sonic if they could be good freedom fighters to which he considers risky. The high stakes would be "Mobius free of Robotnik".
Sonic and Tails rush to the news stand to pick up the month's new issue of their favorite comic, Crack Ups. Meanwhile Scratch and Grounder have also obtained the new issue. Scratch and Grounder are so distracted by their comic that they are not paying attention to Dr. Robotnik as he introduces his new inescapable prison, "Robotnik's Rot-Your-Life-Away Dungeons". Dr. Robotnik grabs the comic away and is outraged to find the main joke in the comic is an animated strip based on Humpty Dumpty starring Robotnik as the titular character. Outraged of being mocked by his egg-shaped physique, he orders Scratch and Grounder to capture the artist who drew the comic to be his first prisoner.
Scratch and Grounder easily capture the artist, a crazy bird by the name of Sketch Lampoon. Sonic, having just read the comic imitates Robotnik's act while cracking up hard suddenly hears the kidnapping of Lampoon on the radio so they rushed to "Robotnik's Rot-Your-Life-Away Dungeons]]" to rescue Lampoon. As part of his plan, Sonic allows himself to be captured but the plan backfires when Robotnik tells the hedgehog he built a super special prison just for him with lasers, spears and a spike ball that automatically shoot and smash anything that is hedgehog blue. Robotnik leaves Scratch and Grounder on guard while he goes and forces Sketch Lampoon to draw him handsomely with muscles in his new issue of Crack Ups.
Robotnik is furious at Sonic making fun of him, so he sends him to the cell for interfering his plans once again. While imprisoned, Sonic pretends that he is reading next month's issue of Crack Ups that he claims Sketch Lampoon gave him. Wanting to see it, Scratch and Grounder open the cage and grabbed the issue. Sonic tapes a poster of himself on Grounder's back, stating that he may be a little taller but they've got his hedgehog blue color just right. They realize it's this month's issue and Scratch notices the poster on Grounder's back. The spears, lasers and spike ball all attack Scratch and Grounder, then Sonic escapes.
Sonic and Tails then go around and set off all the security alerts, overloading the system. The Prison starts to crumble and fall apart. Sonic frees Sketch Lampoon and grabs Tails, as they race out of the prison (and Scratch and Grounder who also escape) just before it collapses. Dr. Robotnik is left on his back crying and yelling "I've fallen and I can't get up!", exactly imitating his act in this month's issue of Crack Ups.
Inside the fish-infested Warp of Confusion sits the disgruntled scientist, Doctor Warpnik, who is angry at his cousin, Dr. Robotnik, for banishing him to this strange place. He watches Mobius through a telescope, plotting his revenge.
Scratch, Grounder and Coconuts each prepare their own trap to catch Sonic. They set a single Chili Dog on a table in the middle of the three traps. Scratch has a "Sonic-Snatcher"; a machine with a chicken-claw attached to a coil (keeping to his theme of chicken/egg-related inventions). Grounder has four catapults loaded with fish, anvils, a chest of drawers and a large safe. Coconuts has a cannon which makes the target explode when triggered (fitting with Coconuts' fondness of lasers, cannons and such weapons). Sonic and Tails smell the chili dog from far away and they know that it's a trap. To Tails' disappointment, Sonic insists that he gets the chili dog on his own and that Tails should stay put.
Sonic grabs the chili dog and makes all three traps backfire on the Badniks. Some smoke and fish from the traps make Tails think Sonic is in trouble, so he comes to help. The Badniks grab Tails and tie him up. Sonic returns to where Tails was waiting and does not find him. Sonic quickly rescues Tails from the three robotic goons and yells at him for not staying put, but eventually forgives him and states that he is important to him. Dr. Warpnik watches them through his telescope projector object and realizes that he can use Tails to lure in Sonic, which will lure in Robotnik.
The next morning, Sonic wakes up to find that Tails is missing. Sonic goes to Dr. Robotnik's fortress and asks Robotnik where Tails is. Robotnik insists that he did not capture Tails, but he continues to talk to Sonic, distracting him so his badniks can catch him off guard. Robotnik asks Sonic if he and Tails had a misunderstanding between them. Sonic says they did. Robotnik says Sonic probably made him run away. Sonic feels bad, but still does not get caught by the Badniks sneaking up on him. Sonic leaves to find Tails, and Robotnik and his three goons follow him with hopes of catching him off guard.
Sonic follows Tails' tracks into the Warp of Confusion. He is welcomed by Dr. Warpnik who reveals that he captured Tails and now he and Sonic are his prisoners. He also shows Sonic an old movie of Robotnik literally throwing him into the Warp of Confusion. Sonic's boredom makes him angry. Robotnik, Scratch, Grounder and Coconuts show up after finding the entrance through a trash-bin, which Coconuts accidentally uncovered by leaning against a rock which fell over. Robotnik and Warpnik get into a fish fight. Sonic unties Tails and they start looking for a way out. Trying to prevent their escape, Dr. Warpnik fires a cannon that turns fish into monsters. Sonic and Tails run around avoiding the monsters. Dr. Robotnik tries to use the machine, but Dr. Warpnik gets mad at him. The cannon hits Scratch, Grounder and Coconuts, turning them all into monsters. Since they are large and powerful, the three Badniks decide to teach Robotnik a lesson for treating them badly. They try to hit him, but hit the cannon instead. The cannon sets alight and Scratch states that they 'laid an egg' (messed up). Robotnik and Warpnik try to put out the fire with fish. With the cannon broken, Sonic and Tails are able to escape the Warp of Confusion.
Back in the real world, Sonic apologizes for getting mad at Tails. Tails says he would never run away because they are best buddies. The bin explodes and turns to dust, but the Warp stays intact. Sonic says it's good to know that Robotnik and Warpnik would be stuck with each other for a while.
Back in the Warp of Confusion, Scratch, Grounder and Coconuts, who are still monsters, share a bucket of popcorn as they watch Robotnik and Warpnik slap each other with fish.
Scratch and Grounder race down a road, complimenting Dr. Robotnik for creating his latest invention, the "Electro Suction Plate", which has a magnetic pull strong enough to stop Sonic from running. Placing the device on the ground, the two hide and activate the plate's powerful suction beam. However, the beam flies right up into Mobius' atmosphere just as Prince Charnock and his advisor Splorg fly past the planet from their extended vacation, Splorg reminding the touring prince of his coronation in two hours time. Prince Charnock decides to briefly visit Mobius, desiring to explore it. However, their spaceship gets caught in the suction beam and is dragged to the ground where it is wrecked.
Sonic and Tails witness the crash landing and race to help Prince Charnock and Splorg. Splorg panics about their wrecked ship whilst Prince Charnock is more interested in taking photos. Scratch and Grounder approach the aliens, capturing them to remove their ship to retrieve the Electro Suction Plate. Sonic and Tails arrive, Sonic freeing the aliens and tossing the Badniks off a thousand-foot cliff. Sonic returns to the aliens, and greetings are made, Prince Charnock revealing he is to be king of the planet Rhombus. Splorg interrupts and reminds that unless Prince Charnock does not return to Rhombus within the two hours he mentioned to become king, his baby brother legally becomes king and he will more than likely order for Mobius' destruction. Sonic agrees to assist the aliens rebuild their ship, racing around Mobius and collecting the scattered pieces. Splorg uses a device to automatically reconstruct the spaceship. However, he realizes two vital pieces are missing; the cockpit's pressurizing canopy and the navigational nosecone with an embedded miniature steering chip.
Scratch and Grounder clamber back up the cliff, Grounder's nose repeatedly falling off. Sonic, Tails and the aliens walk through a forest of curly trees, Prince Charnock commenting they have "nothing like [the trees] on Rhombis" (which becomes a running gag in the episode). He nearly gets bit by a snake but Sonic saves the oblivious prince. They come across a river where Tails spots the pressurizing canopy on a tree branch and retrieves it. Scratch and Grounder appear, attempting to use the suction plate again, but Prince Charnock is too interested in taking photos of a sunfish. But the Badniks have it backwards and end up magnetizing themselves to it before falling down a waterfall. Sonic and co. continue on, finding a quarry filled with rocks shaped like sports equipment (dominoes, bowling equipment, etc.) Splorg spots the nosecone, Sonic getting it. Scratch and Grounder reappear and fire the suction pad again but instead magnetize a boulder who causes a landslide, burying everyone and saving Tails and Splorg. Sonic and Prince Charnock emerge, and run off with Grounder's nose, whilst the Badniks find the nosecone.
Back at the spaceship, the aliens panic with only twenty-five minutes to go, but Sonic realizes the object they have is Grounder's nose and comes up with a plan to regain the nosecone. The Badniks realize what they have and place the nosecone in the suction plate hoping Sonic will attempt to steal it but get stuck in the process. Grounder decides to telephone Dr. Robotnik to tell him of the events. Dr. Robotnik is busy cleaning his beloved Egg-O-Matic when he receives the call from Grounder and heads out to aid his minions.
Sonic, Tails and the aliens find the Badniks, Sonic revealing the aliens plan to use Grounder's nose as their nosecone and go to leave. Grounder goes hysterical at the thought of never seeing his nose again, and gives chase and Scratch following to try to tell him that it is all a trap, Sonic and co. tossing the nose about until Sonic drops it on the suction plate and snags the real nosecone when Scratch turns off the plate. The enraged Scratch tortures Grounder using the suction plate and then proceeds to crush his nose using the plate. Sonic arrives to finish off the Badniks, dressed as a woman with fruit on his head, like a fruit-hat but decides to leave upon seeing Scratch taking care of Grounder's nose.
Returning to his friends, Sonic finds them at Dr. Robotnik's mercy. Tails has been captured, Dr. Robotnik threatens to atomize Tails into molecules unless Sonic surrenders himself, and also happens to possess the nosecone. Sonic ends up bound and gagged in a cage, and Dr. Robotnik tosses the nosecone to the aliens. While Splorg is more than eager to rush away, Prince Charnock is objective and laments he would not be much of a king he cannot help those who have helped him. Getting an idea, Prince Charnock goes to Dr. Robotnik and compliments the Eggomatic, asking if he can take a picture of it. Dr. Robotnik agrees, but Prince Charnock deliberately bumps into the domino-shaped rocks, causing them to collapse on top of Dr. Robotnik and the Eggomatic. Prince Charnock frees Sonic from his bonds and gag and the group race for the spaceship with few minutes remaining.
The aliens rebuild the ship and leap into it with only five minutes to spare, Splorg realizing they will have to go to hyperspeed to reach Rhombus. Sonic asks Prince Charnock why his baby brother wants to destroy Mobius, but the prince reveals his brother is literally his baby brother, only being two years old. The aliens fly off into space, Prince Charnock referring to Sonic and Tails as "jolly good fellows".
Momma Robotnik storms into Dr. Robotnik's fortress to tell her son that she escaped the Mobius Home for Really Bizarre Mothers and that it is her birthday and as a present she wants him to destroy the Mobius National Park. Dr. Robotnik sends Scratch and Grounder with a group of tree destroying robots to do as his mother wishes.
Sonic and Tails see the robots destroying the trees and Sonic begins to destroy them. Grounder comes up with a plan to catch Sonic, but Sonic buts in disguised as a robot repair man. Sonic convinces them that he is fixing their robots when in actuality he reset the robots to attack Scratch, Grounder and Robotnik. Robotnik and Momma Robotnik arrive in time to be attacked by the robots.
Moving on, Robotnik and Momma Robotnik are at home, watching Scratch and Grounder destroy a Mobian town using giant walking robot legs. Sonic, disguised as a game show host, tricks the Badniks into opening a door to a bunch of water and they get washed down a drain. Momma Robotnik is furious at her son for not being able to do anything right and says as a birthday present to herself, she is going to catch Sonic.
Tails comes across Momma Robotnik crying on the ground saying she lost her son because he has turned evil. She shows Tails a roll of film showing Robotnik as a baby and how he lost his Fuzzy Wuzzy and that turned him bad. She tells Tails that if he had his stuffed bear back, he would be a good boy again. She gives them an address to go get it in Chaos City. Tails leaves a note for Sonic. Momma Robotnik then says Tails is so gullible after he left.
Sonic finds Tails' note and goes after him. He gets lured into a trap by Coconuts disguised as a chef giving away free Chili Dogs. His pot of Chili turns into an angry robot which Sonic quickly defeats and continues on to Chaos City. After avoiding a trap set by Scratch and Grounder, Sonic makes it to the old Robotnik home and finds Tails tied up. Sonic frees him, but they cannot escape because Momma Robotnik turns a pile of trash into a birthday cake and turns the gate into an electric fence using a machine on her watch. She then releases Fuzzy Wuzzy from the birthday cake. Fuzzy Wuzzy is at first a cute little teddy bear, but he snarls loudly and then transforms into a large, muscular, four armed, two headed angry, stitched up bear monster. Tails is terrified of this and cowers in fear, realizing that was the little Fuzzy Wuzzy he was sent for. Sonic says that he would hate to see the big Fuzzy Wuzzy. They run away but Fuzzy Wuzzy grabs Tails with his two left arms.
Sonic ties a rope to Fuzzy Wuzzy and grabs Tails from Fuzzy Wuzzy, tripping him over. He then ties the other end to the electric fence. Robotnik is horrified as his Fuzzy Wuzzy is getting electrocuted and going bonkers, turning into a robotic skeleton, a skewered sausage with Fuzzy Wuzzy's two faces and a bat batting Fuzzy Wuzzy's heads attached to the bat by a string for each head. Robotnik begs Sonic to save him. Sonic says only if Robotnik promises to be good. Robotnik promises. Momma Robotnik hits her son with an umbrella for promising to be good. Sonic saves Fuzzy Wuzzy who then drops a big birthday cake on Robotnik and his mother and then sings "We wish you a happy birthday". Two workers from Momma Robotnik's home show up and drag her into their vehicle and take her back to the Mobius Home for Really Bizarre Mothers. Robotnik is glad to be rid of her. After saying that, the vehicle comes back and Mama Robotnik sticks out her umbrella and whacks Robotnik on the head. The vehicle then speeds off again.
Sonic tells Tails that he is the one who called the home and told them where Momma Robotnik was. The two friends run off to get some chili dogs.
pursues Sonic in Robotonik's Egg-O-matic. Sonic tricks Coconuts into crashing and smashing up the vehicle. When Coconuts goes home and tells Robotnik, the furious doctor fires him and launches him out of his fortress. Robotnik goes to his basement to talk to Big Daddy, a giant gorilla who he has caged up and plans to use to take over Mobius. Big Daddy roars at Robotnik as he is not under Robotnik's control yet.
Coconuts lands in a tree next to a large baby ape named Boom-Boom who thinks Coconuts is his daddy. Coconuts realizes Boom-Boom has super strength and decides to use him to help capture Sonic and get back on Robotnik's good side by pretending to be his daddy.
Coconuts and Boom-Boom set a trap for Sonic. But Sonic and Tails spy on them and decide to get it to backfire on Coconuts. Sonic tells Boom-Boom that Coconuts is not his Daddy. Boom-Boom cries and tells him that a bad man took his daddy away in a cage, and that he never found his daddy.
Robotnik attaches a mind control device to Big Daddy and tests it by making him destroy things using a remote control. Robotnik plans to have Big Daddy climb Mount Mobius, the largest mountain on the planet, and install a giant laser so everyone on the planet will have to do what he says. Robotnik tells Scratch and Grounder that they are no longer necessary, and he leaves with Big Daddy. Scratch and Grounder are pleased that they "get promoted from useless". Coconuts comes and tells Scratch and Grounder a plan to get all three of them back on Robotnik's good side.
The three Badniks dress up in a big gorilla costume and go find Sonic and Boom-Boom. Sonic uses a disguise to reveal them as frauds. They then see a big laser fry a tree and Sonic looks up with Grounder's binoculars to see Robotnik and Big Daddy on top of Mount Mobius. Boom-Boom says' Daddyyyyy!' and laughs excitedly at finding where his daddy is.
Sonic, Tails and Boom-Boom climb up the mountain and Robotnik had Big Daddy fire at them with the laser. Sonic realizes the laser gun must be running on batteries, so he decided to run around until they run out of juice. His plan works perfectly, but Big Daddy Ape grabs Sonic and holds him over the edge of the cliff. Tails tells Boom-Boom to try talking to his father, but the mind control device was too strong. Boom-Boom then picks up Robotnik and smashes him on the ground multiple times which breaks the remote control. Big Daddy snaps out of the mind control and recognizes his son. The two apes reunite and Boom-Boom tells his daddy that he lost his rattle. Big Daddy gives Boom-Boom Robotnik to shake around instead.
A singer named Catty Carlisle is invited to the REBL studios by Mad Dog Max. Catty starts singing a song in a Texas style as she dedicates it to "Mobius' number one hero, Sonic".
Meanwhile, Scratch and Grounder are on a mission to capture Sonic by using a bear trap. As the two get distracted by a radio playing 'Sonic's Song', Sonic comes and makes fools of them and they get trapped instead. Scratch and Grounder go back to Robotnik and he gets upset that Catty is singing a song about Sonic. So Scratch and Grounder head to REBL studios and try to capture Catty but Sonic dresses as an interviewer and distracts the two by saying that they have just become instant stars on radio. As that happens, Robotnik decides on another plan by making only one song in the whole of Mobius that is Robotnik's anthem, so he creates the Music Destroyer (M.D.) to put an end to all other music. After he captures Catty, Sonic and Tails try to save her but end up being captured themselves. Sonic manages to trick Scratch and Grounder into freeing them and plays very loud rock music to destroy the M.D. Sonic returns Catty's guitar and she walks into the sunset with Sonic and Tails, singing Sonic's song.
Just as Robotnik frustratingly questions his ability to get rid of Sonic with such unreliable aid as Scratch and Grounder, an energetic salesman comes to Robotnik's doorstep introducing himself as Wes Weasely, a representative of the Handy Dandy Super Villain Appliance Distributors Limited Company (or H.D.S.V.A.D.L.) Robotnik takes a liking to Weasely's brash, obnoxious, pushy, rude demeanor and odd attire, and immediately hires the salesman. Weasely's first invention is the Darkinator, a vacuum-like device that makes the immediate surrounding area dark when activated. Despite the enormously high price of the device, Robotnik buys the Darkinator. Unfortunately for Scratch and Grounder, the darkness caused by the Darkinator does not completely reach the ground, allowing Sonic to use the robots' stupidity to destroy the machine.
Weasely then introduces the Freeze Banger, a flash freezing device, which Robotnik buys two of. Sonic's exceptional jumping abilities cause Scratch and Grounder to freeze each other with the device, after which Sonic thaws (and melts) the robots with his supersonic speed. After Robotnik repairs his robots, Wes, having become rich because of Robotnik, introduces the HDSVADL's latest weapon: the Gravity Stopper, a device that allows anything it zaps to become weightless. The device appears to be successful this time around, but when Tails carries Sonic off faster than usual (thanks to the absence of gravity), Scratch takes off his Self-Gravity Boots and step into the Gravity Stopper's path in an attempt to catch them, but is unable to without gravity, forcing Grounder to deactivate the machine and allowing Sonic and Tails to escape.
Back at the hilltop fortress, Wes cites Scratch and Grounder as the reason for the failure of the last three contraptions, and gives Robotnik a chance to use his new De-Atomizer, a weapon shaped like a perfume container that causes anything it is used against to disappear. As to make sure the weapon works, Robotnik assigns a reluctant Weasely as the supervisor of Sonic's capture. Near a corn field, Scratch accidentally pushes an untested button on the De-Atomizer, causing an upcoming Sonic to split into five. After disposing of Scratch and Grounder, Sonic forces Weasely to reverse the effects of the cloning. When Weasely attempts to sneak away, he reveals that he is trying to escape from Robotnik as to avoid his wrath. Sonic travels to the hilltop fortress under the disguise of a HDSVADL salesman and uses all of Weasely's past contraptions combined into one against Robotnik. As Sonic reveals himself and leaves, Robotnik, Scratch, and Grounder yell out "We hate that hedgehog!"
The story starts as Tails and Sonic sneak through the fortress of Dr. Robotnik. In there, they find Lucas, who has bee locked up by Robotnik for thirty years. Sonic immediately frees Lucas, but it triggers Dr. Robotnik's robot armies, who were later defeated by Sonic. In anger, Dr Robotnik decides to use his secret weapon, the eggbomb. That too, was countered by Sonic, and together with Tails, Sonic escaped the fortress. When they escaped to the forest, Lucas decided to tell them what this was all about in a flashback. In his story, Lucinda liked Lucas and in return, Robotnik was jealous and imprisoned Lucas. Hearing this Sonic decides to help him find Lucinda.
Meanwhile, back in the fortress, Scratch and Grounder also gets curious about this whole thing and Dr. Robotnik tells them what happened, only it was completely opposite from Lucas's story. Then Dr. Robotnik decides that he'll give any prize to one who captures Lucas, who stole "something" from him other than his power. Scratch and Grounder go out to capture Lucas, only to fail and accidentally blurt out the location of Lucinda. Now knowing the location, Sonic, Tails, and Lucas go out to get Lucinda and Lucas back together. When they arrived, Lucas decided to call Lucinda, despite his nervousness, only to be captured by Scratch and Grounder. Lucas was thrown into a volcano, and Dr. Robotnik goes to see Lucinda, not knowing that Sonic actually made it out of the volcano with Lucas. Sonic decides to dress as Lucinda and fool Dr. Robotnik. The plan works and Lucas and Lucinda got back together again.
Scratch and Grounder are conducting the Robotnik Express, a train filled with explosives that they must deliver to Dr. Robotnik. Upon trying to stop them, Sonic and Tails get captured, allowing Scratch and Grounder to celebrate out loud. Hearing the Badniks celebrate, Da Bears come to help. Before Da Bears arrive, Sonic and Tails escape and wrap up Scratch and Grounder like mummies. Da Bears show up and free Scratch and Grounder thinking they are Sonic and Tails. Scratch and Grounder play along saying that they are indeed Sonic and Tails and need Da Bears' help in capturing Grounder and Scratch. They describe Scratch as being Spiny and Blue and Grounder having two tails.
The brakes on the train get broken at some point and Sonic realizes there's a bridge above the buffalo village that is out. In order to save the village, Sonic places a tree at a very stiff switch, so when the train hits the tree, the tree will pull the switch and the train will switch tracks.
Sonic continually uses his silly costumes and manipulating tactics to humiliate and hurt Scratch, Grounder and Da Bears. Sonic realizes he has gone too far when Da Bears are stuck on the front of the train while it is headed for a cactus patch. Sonic uses the tree he left at the switch to bump Da Bears onto the top of the train and safe from the cacti. Sonic and Tails then convince Da Bears that they had been tricked by Scratch and Grounder. Da Bears ask how they can redeem themselves and Sonic asks them to help save the buffalo village.
Using their cars, Da Bears and Sonic make haste in fixing the bridge above the buffalo village. Realizing they won't get it done on time, they tilt a piece of the bridge upward making a ramp, allowing the train to jump the gap over the village. The Buffaloes all cheer and rejoice that their village is saved.
The Robotnik Express arrives at the bomb factory on time, but since the brakes don't work, they crash into the factory making the whole thing explode. Dr. Robotnik, Scratch and Grounder all fly off holding onto a giant rocket, with Robotnik screaming "I hate that Hedgehog!" Da Bears wave good-bye to Sonic and Tails as they leave.
Robotnik has kidnapped Professor Von Schlemmer and has forced him to tell how to create his Gizmo Gas machine. Scratch and Grounder finish putting together the Gizmo Gas machine, but when tested, it fails. Robotnik, now furious, tortures Von Schlemmer to see what they have to do to get his contraption to work (by tickling his feet with a feather), and Von Schlemmer finally reveals what to do. Robotnik then sends Von Schlemmer to the deepest darkest hole in the Jungle of Doom.
Meanwhile, Sonic and Tails are being chased by Coconuts, but they easily get rid of him. The two heroes then arrive in Wienerville, the weenie capital of Mobius. Mayor Knackwurst greets Sonic and Tails and insists on feeding them a feast. Tails gobbles down a ton of food and leaves to get some dessert. At the same time, Robotnik tests the machine on a piece of belly-button lint, but the machine explodes and casts Gizmo Gas into the air, and it eventually settles on Tails, who breathes it in as it rolls into town. Tails grows to an enormous size and gets very hungry and starts eating and breaking the whole town. He leaves so as not to hurt anyone. The citizens of Wienerville are quick to forgive Tails until Robotnik flies in on his Egg-O-matic and tells them that Tails did it on purpose and Sonic is the mastermind behind the destruction. They don't believe Robotnik until he gives them all a bunch of free gifts. The citizens then turn on Sonic and Tails.
Tails continues to grow and continues to eat whatever he can. Tails' burps cause earthquakes. The citizens go after Tails like he is a monster. Robotnik leaves and puts Scratch and Grounder in charge. Sonic overhears them talk about Von Schlemmer, so he tricks them into telling him where to find the Professor.
Sonic runs to the bottomless pit in the Jungle of Doom and pulls Professor Von Schlemmer out with a crane. Von Schlemmer tells Sonic that the antidote to the Gizmo Gas is the fragrance of the rare Hoot-n-Toot Garlic from the garden of the evil wizard lizard. Sonic runs and gets it.
Meanwhile, the Wienerville citizens have Tails cornered in a canyon. Tails tries to justify his actions, but they do not listen. Sonic and Von Schlemmer arrive with the garlic, but the citizens insist Robotnik uses his Insto-Freeze Cannon to turn Tails into a Popsicle. Von Schlemmer gives Sonic blueprints to build the world's largest wiener launcher which fires a giant Chili Dog (with the garlic on it) into Tails' mouth. Tails shrinks back to normal and Robotnik's freeze ray misses him and bounces back at the villains, hitting them. Professor Von Schlemmer explains everything to the Mayor. The diner's waitress asks how to make things up to Sonic and Tails. Tails asks for 746 Chili Dogs and some dessert.
When Tails is being attacked by Scratch and Grounder. Sonic shows up to help his little buddy. As Sonic makes light work of Scratch and Grounder, Tails ends up falling out of a tree and getting injured. Sonic feels very guilty about Tails getting hurt and declares that he would never let something like this happen again.
Sonic puts a bandaged Tails in a wagon while explaining to him that he is going to find him a real family. Tails insists that he does not need a real family, but Sonic tells him otherwise. The first family is a pair of clumsy Storks who flood their own house and set it on fire. Tails says he would be safer living with Robotnik. The second family is that of Sergeant Doberman, who treats Sonic and Tails like new recruits. Sonic and Tails quickly retreat.
When all hope seems lost, Sonic and Tails find a billboard with a picture of Baby Tails on it which catches Tails' attention. Scratch and Grounder are hiding behind the billboard. Scratch speaks through a microphone, explaining that the child's real parents miss their baby and giving an address. Tails gets very excited to hear that his real parents are looking for him. Sonic is a little bit sad at the idea of losing his friend.
They follow the address, where "Tails' parents" are. They give Tails lots of toys and food and he is very happy. "Tails' father" tells Sonic that Tails belongs with his own kind. So Sonic says goodbye and leaves. Dr. Robotnik watches from a telescope far away. He notices a tear roll down Tails' cheek. Dr. Robotnik then explains to Scratch and Grounder that his plan to capture Tails is working perfectly.
Tails' parents reveal themselves as Badniks and capture Tails.
Sonic sits by a rock and remembers the time that he first met Tails. In a flashback, Baby Tails falls and lands on top of Sonic. He tells Sonic that his name is Miles and that he hates it. Sonic gives him the nickname "Tails". Sonic snaps out of the flashback and realizes that if those were really Tails' parents they would have called him 'Miles', not his nickname.
Back at the house of Tails' fake parents, they tied up Tails and, Dr. Robotnik has set up two traps for Sonic: the Magnetic Sneaker-Gripper Hedgehog-Trapper Rug and the Ceiling-Squasher Sonic-Smasher Cruncher. Sonic arrives disguised as a mailman and tricks Robotnik, Scratch and Grounder into getting crushed by their own traps.
As they walk together, Sonic apologizes to Tails for the whole ordeal; however, Tails explains that he already has a family. He tells him that he is his mother, father and picket fence. Sonic tells him that he loves him and Tails says he is glad to be home.
Sonic and Tails cross paths with an old hero named Captain Rescue, only to come to regret it. He insists on helping the two heroes out in their adventures, but he ultimately just makes things worse. Sonic eventually has enough and makes it perfectly clear that he doesn't want Captain Rescue around. Doctor Robotnik, on the other hand, wants him to stay and easily manipulates the old hero, creating big trouble for Sonic. Now, Sonic's life depends on Tails and a regretful Captain Rescue.
As Scratch and Grounder watching their favorite show "Edgar Eagle". Dr. Robotnik comes into the room to see what is going on and makes the Badniks kiss his feet instead. As usual, Scratch and Grounder argue over who Robotnik likes more, so Grounder challenges Scratch to a race, claiming that whoever caught Sonic first would determine who Robotnik likes more. Grounder jets out of the door, leaving Scratch jealous that Grounder is faster than him. Soon, a commercial airs on the television advertising an authentic, easy-to-build Eagle Chopper. Scratch, convinced it will help him catch Sonic, buys an Eagle Chopper.
Unfortunately for him, construction of the chopper was way more complicated than advertised! The next morning, Scratch has completed the chopper, although it looks nothing like the real chopper. He took off in it, hoping it will catch Sonic. Later, Sonic and Tails were heading towards the farmland to answer a distress call from Farmer Peck, when Scratch arrived in his chopper, shooting flaming egg bombs at Sonic. After being outsmarted by Sonic, Scratch crashlands in the farmlands, where Henrietta finds him. The crash altered Scratch's memory, making him think that he was Edgar Eagle.
Meanwhile, Farmer Peck explains to Sonic that Robotnik wanted to destroy his farm and build the planet's largest robot factory. Sonic tries to stop the robots, but to no avail. Soon, Henrietta appears with the deluded Scratch, saying that he was a big star, leaving Sonic confused. This time, Scratch tries to destroy the factory, but Sonic drags him to safety as the robots shoot at them. Sonic and Tails manage to use Scratch's delusions and his knowledge of Robotnik to their advantage. Once Sonic, Scratch, and Henrietta arrive near Robotnik's fortress, Grounder tries to lure the trio into a trap by setting up a chili dog vending machine that turns into a rocket when activated. Fortunately, Sonic safely brings the two back to the fortress unscathed, while the rocket crashes into Grounder. Once they infiltrate his fortress, they find the remote that controls the robots in Robotnik's lab coat pocket, but Robotnik arrives and orders Grounder to capture Henrietta. He then threatens to kill her if they don't give him the remote.
Scratch then jumps on Robotnik's leg to distract him while Sonic saved Henrietta. Robotnik flings Scratch off of his leg, slamming him against the wall and restoring his full memory. Using the remote control, Sonic sets the robots in reverse, then destroys the remote to prevent overriding the command. As Sonic and Henrietta escape, Robotnik advises to escape the fortress before destruction, but not without "turning Scratch into a toaster oven" first. Later, back at the farm, Farmer Peck thanked Sonic for reversing the robots and returning the farm back to normal, although he is quite upset about Henrietta being heartbroken by Scratch. So, Sonic makes a phone call and the real Edgar Eagle arrives to spend time with Henrietta. Afterwards, Sonic gets the idea that he should have his own TV show one day just like Edgar Eagle.
After destroying some angry Buzz Bombers, Sonic reads about a town called McGuffin has declared tomorrow to be "Sonic Appreciation Day" in the newspaper. Sonic and Tails head for the town. The dog who works the news stand makes a mysterious phone call telling someone that Sonic is on his way and he has his sneakers with him.
At McGuffin, Sonic and Tails meet Harry the Hucker who sells Sonic merchandise. As a courtesy he gives Sonic a free blue Sonic book mark. Scratch and Grounder attack driving the Monster Robot Sonic tracking Device. Sonic uses a "Sonic Day" banner to tie up its legs and send it smashing to the ground. Sonic then hears cries for help on top of a near by building. A Squirrel named Sonnette is on the edge of a building and she falls. Sonic catches her and she is very excited, introducing herself as his biggest fan and consumer of all Harry's cheesy Sonic Merchandise. She also confesses that she jumped off the roof just to meet Sonic. Thinking she's crazy, Sonic drops her on the ground and leaves. Sonnette gets angry and swears she'll get even with him.
While checking into a hotel, Sonic and Tails are approached by a bell boy named Hodgepodge, who is old friends with Sonic. Sonic challenges him to a race just like old times. They race on a track built for Sonic's speed demonstration on Sonic Day. Hodgepodge is very fast, but still can't keep up with Sonic. Hodgepodge tells Tails how he used to be the fastest until Sonic came along and he used to be jealous. He playfully kicks Sonic while Coconuts, in an Italian old man disguise, spies on him. Sonic runs away and Coconuts says Sonic will soon be checking out forever.
Meanwhile, at Dr. Robotnik's fortress, Robotnik loses at cards to a card playing Robot. In anger, Robotnik takes out a laser gun and shoots the robot multiple times until it is dead and he kicks it into a pile of other dead robots. Scratch and Grounder come and tell Robotnik they were defeated and about "Sonic Appreciation Day". Robotnik gives them his new Robo-Roller, a vehicle that can flatten an entire city. He gives the Badniks an order to squish Sonic and his fans into a squishy paste.
While Sonic and Tails are asleep in the hotel, a tube comes through the door and it sprays green gas all over the room. Sonic wakes up to find his Sneakers are gone. Sonic shows Tails that when he runs, his feet burn up when he runs without his hi-tops. Tails assures him that they'll solve the mystery of who took them and get his shoes back. While looking for clues, Tails finds Coconuts sleeping in the closet. They tie him up and threaten to take him apart. Coconuts tells them that he hid in the closet so he could get them in their sleep, but when the hose sprayed its gas in the room, he fell asleep.
Tails assumes Hodgepodge stole the hi-tops. They go outside and Tails jumps on Hodgepodge, shaking him and accusing him of stealing the shoes. Sonic gets Tails off him and says he believes he is innocent. Hodgepodge tells them that he heard Robotnik and his Badniks are going to attack the town.
Sonic sees Sonnete and accuses her of sneaking in his room last night. She confesses that she did sneak in and she stole a chili dog wrapper and a red Sonic bookmark. Sonic has the mystery figured out, but it is too late. Scratch and Grounder attack the town in the Robo-Roller. Sonic tricks them into driving on the speed demonstration ramps. The trick backfires at first when Coconuts tells Scratch and Grounder they're being tricked, but Sonette shuts him up by covering him with bubble gum. Sure enough, Sonic's plan works and the Robo-Roller falls off the ramps and is destroyed. Sonic then places the flattened badniks in a giant envelope and puts it in the mailbox, calling it "junk mail".
Sonic gets a dog policeman to arrest Harry the Hucker. Sonic finds his shoes in Harry's souvenir stand and proceeds in telling Tails how he knew it was him. Sonic says Harry must have dropped the red bookmark and when he went to pick it up, he grabbed Sonic's blue one instead. Harry explains that he wanted to cut up the sneakers and sell the pieces as souvenirs. Fido takes Harry away. Sonic mails a talking t-shirt of himself to Robotnik saying he is now a member of the Sonic fan club, annoying him. Robotnik yells "I hate that hedgehog!"
As Sonic is out running, he sees a strike of lightning open up an interdimensional portal. A small black glob type creature comes through the portal and follows Sonic to a place where Tails is preparing Chili Dogs for lunch. Tails likes the creature and decides to name him Goobster and keeps him as a pet. Goobster eats all their Chili Dogs.
Scratch and Grounder attack in fighter planes and Goobster helps Sonic to defeat them. Goobster gets hungry so Sonic offers him steak and a sandwich, but Goobster only wants Chili Dogs. Goobster becomes large and starts sucking up everything in sight. Sonic gives him his retirement chili dogs and Goobster calms down.
Dr. Robotnik is angry that Scratch and Grounder failed once again. Scratch and Grounder say it was because of Goobster. Robotnik tells them to kidnap Goobster to lure Sonic and Tails into a trap.
Sonic figures out that Goobster is from another dimension, but before he can do anything about it, Goobster is captured by Scratch and Grounder.
In Dr. Robotnik's fortress, Goobster starts to eat everything in sight. Robotnik decides to use Goobster to get rid of Sonic and take over Mobius. When Sonic and Tails arrive, Goobster is hooked up to an electric machine that shocks him and makes him start sucking up everything. He quickly sucks up Sonic and Tails, but then burps them back out. Sonic frees Goobster and the three escape.
It begins to rain and Sonic takes them back to where he first saw the interdimensional portal open. They wait for lightning to strike again, but Robotnik and his Badniks attack. Sonic uses Grounder as a conductor and lightning strikes, opening the portal. Goobster goes through the portal where he is happily reunited with his parents. Tails is sad to see him leave, but Sonic cheers him up by saying he can get a new pet.
Dr. Robotnik has invented Club Robotnik, a luxury escape that captures its guests and makes them into his slaves.
Sonic and Tails find themselves in Scrap Valley where they meet Wallace A. Ditso and Torch who introduce them to their society of mechanically challenged robots. Ditso tells Sonic of a project that Robotnik is working on and Sonic goes to investigate.
Sonic and Tails spot Robotnik's blimp, so Sonic goes in disguised as a pizza delivery boy. He pulls a trap door that makes Scratch and Grounder fall out of the blimp. Robotnik gets Sonic in a trap. After the commercial break, Scratch and Grounder are somehow back on the blimp guarding Sonic as Robotnik reveals his plans to flood Scrap Valley and create Robotnik Lagoon. Robotnik and Scratch leave with Grounder guarding Sonic. Robotnik mentions he will use Sonic as target practice with his new Hedgehog Harpoon. Sonic tricks Grounder into releasing him. Sonic tells Scratch and Robotnik that he's escaped. The three villains chase Sonic up on top of the blimp. Robotnik fires his Hedgehog Harpoon and pops the blimp.
Sonic returns to Scrap Valley where he tells the robots about Robotnik's plan. They are suddenly attacked by a giant Crab Compactor that eats their buildings and excretes them out as little cubes. Outraged, the rejected robots agree to assemble with Sonic and Tails to take down Dr. Robotnik. They all go through the resort and sabotage everything from the pipes to the food.
At the opening of the resort, Robotnik is giving a speech, dedicating the place to himself. The audience drown him out with laughter as Sonic and Ditso project pictures on the large screen of Robotnik as a pig and Robotnik naked in the shower. Even Scratch and Grounder laugh. Scratch unplugs the screens, but Sonic replaces Robotnik's microphone with his own voice insulting him. Robotnik jumps to the cutting of the ribbon, but because of all the sabotage, the ribbon was the only thing holding the resort together. Once it is cut the entire place collapses and Robotnik yells, "I hate that Hedgehog! I hate him, I hate him! How am I supposed to turn Mobians into slaves if he keeps ruining my plans?" Sonic reveals to Robotnik that he was on TV as he said that and all the Mobians in the audience turn on Robotnik and hit him with fruit.
For the sake of revenge, Robotnik pulls the lever to flood Scrap Valley, but because of the sabotage the water comes up from under Robotnik and sends him up in the air.
Ditso declares that they can use what's left of Club Robotnik to rebuild Scrap Valley.
Doctor Robotnik builds Pseudo Sonic, a mechanical lookalike of his real counterpart in order to spoil the famous hedgehog's image and get Sonic in jail. The robot is piloted by a lab rat named Lawrence who is forced to commit crimes to save his parents. Pseudo-Sonic quickly manages to ruin Sonic's good reputation while the real Sonic is standing in the same spot watching TV. When racing against each other, Sonic and Lawrence accidentally fall in a patch of poison flowers in Poison Flower Valley and really get itchy and soon swell up. Tails helps them get out of the patch and takes Sonic and Lawrence to the hospital, and Sonic falls asleep. Tails decides that Sonic being out of commission for 'a day or two' is too late for Lawrence's parents and sets out to save them. Tails uses the robot to bother Robotnik on the way.
Meanwhile, Scratch and Grounder believe that Pseudo-Sonic is the real Sonic, but Robotnik manages to set them straight. Meanwhile Sonic knows that Tails has gone and gets out of bed. Tails sees Sonic and Sonic tells Tails his plan! However, Sonic and Tails get Lawrence's parents out of Robotnik's laboratory, and Pseudo-Sonic is destroyed, with Robotnik thus ending up in the Mobius General Hospital. Grounder tells Robotnik that at least he still has them. Robotnik responds by beating Scratch and Grounder up. The episode ends with Robotnik screaming, "I HATE THAT HEDGEHOG!" One of the "H"s then falls into the hospital.
In his fortress, Dr. Robotnik is downloading a genius program that is supposed to improve his intelligence. Meanwhile, Scratch and Grounder are setting a trap for Sonic the Hedgehog, which fails as usual. Eventually, they head back, where Robotnik is still searching for more brain power, attempting to download other computer programs. However, this results in a computer virus infecting his computer, which Sonic and Tails' friend Hacker created when copying the genius program onto a microchip. Hacker is almost captured but is saved by Sonic.
Later, Grounder's head loses various bits and pieces. During his search for the pieces, he accidentally grabs the Genius Chip, and when he places it in his head, he becomes a genius. Sonic tries to get the chip back, but ends up getting zapped by a ray that Grounder reveals has turned him to stone. Grounder then starts treating Robotnik like a prisoner, and Scratch like a slave.
Eventually, Hacker and Tails manage to reverse the ray that zapped Sonic. They discover that he was not turned to stone, but rather encased in stone and Sonic breaks free. Scratch tries to help Grounder take care of Sonic, but Grounder's head falls off, allowing Robotnik to remove the chip while Sonic switches the chip with another. This in turn makes Robotnik stupid. Robotnik then hands the prize to Grounder and Scratch as the lightning rod zaps them while Sonic, Tails, and Hacker escape from the explosion. Robotnik feels he's better off without the chips and yells "I HATE THAT HEDGEHOG!".
While Doctor Robotnik completing a machine and proclaiming that he should be given an award for supreme excellency. Scratch asks him if he got that award the week before. Robotnik tells Scratch to think of a better one. He introduces the machine as the "Super Supreme Stopper Zapper". Scratch and Grounder say, "It looks super!", then Robotnik yells at them. He tests the machine on Scratch who changes to stone. Grounder has some fun with him, fiddling around with his parts and tickling his nose. Robotnik unfreezes Scratch (who sneezes because of Grounder tickling his nose), jumps around holding his head (because Grounder hit him on the head) and dripping water (because Grounder squirted him with water). He wonders what happened and Grounder tells him that it was a bad dream. Robotnik literally throws them into the machine, telling them to fetch Sonic by suppertime. They fly out the building through the wall, and Scratch calls Grounder dumb.
Outside, Grounder and Scratch set a trap that includes a sign with a Chili dog on it. Sonic the Hedgehog runs by with Tails, who is on his skateboard. They stop at the sign and Sonic inquires that he has to check it out. Grounder prepares to launch the rock, but an Elvis bird lands on it and begins to dance. Grounder lets go of the slingshot and chases it away, whilst the rock is launched with Grounder on it. Tails and Sonic jump to avoid it, while Grounder crashes into a bigger rock and explodes. Upon smashing into the rock, The Super Supreme Stopper-Zapper starts to fire. Tails warns Sonic to watch out, where Sonic turns and dodges just in time. As the Zapper continues to shoot, Sonic grabs Tails and they fly off. They dodge all the beams and leave the scene. Scratch and Grounder emerge, cursing Sonic. Grounder's phone rings, and the two Badniks answer it, where Robotnik appears on the line. They say that they almost had Sonic, and Robotnik explodes with anger. Scratch inquires that they will do another plan his way. Robotnik threatens to melt them down if they don't catch Sonic.
Meanwhile, Sonic and Tails begin to hunger, until Tails spots a sign saying "All you can eat Chili Dogs". Tails is excited, but Sonic says its a trap. Tails gets disappointed, but Sonic tells him that he wants the danger, and they head off to the apparent cookout.
Meanwhile, Grounder (who is wearing an "I love Robotnik" apron) listens to Scratch as he explains his plan to zap Sonic. Grounder doesn't understand, to a point where Scratch yells at him that he's as dumb as a rock. Grounder asks, "Metamorphic, Igneous, or Sedimentary?". Scratch names him a made-up rock, and smacks him with it.
Sonic and Tails approach, where the hedgehog orders Tails to stay put. Tails tells him to be careful, but Sonic retorts, and says that he's too fast for them. They high five, and Sonic rushes off. He disguises himself as a chili dog inspector to check the level of chili in their chili dogs, while Scratch and Grounder fall for it. Sonic tells Grounder that his chili isn't hot enough and he will have to close them up. Grounder protests, so Sonic gives him a tin of "Very Hot Chili" that Grounder pours in. He dips a chili dog in and gives it to Sonic. However, Sonic tells him that he's the cook, so he should taste it first. Grounder eats it, and his cheeks inflate and explode with from spiciness. He begins to blow up, while Sonic grabs two normal chili dogs and runs off. Grounder blasts off like a rocket, flies high into the sky, falls back down, and crashes into the ground, leaving a Grounder-shaped hole. He jumps out and rolls away, chased by Scratch on the Super Supreme Stopper-Zapper. It begins to shoot again, so Grounder yells at him to shut it off, to which Scratch says, "I can't! It's stuck!". It continues to shoot at Grounder.
Sonic returns to Tails and gives him a chili dog. Just as Tails is about to eat it, he gives a shout and points behind Sonic. The Zapper is coming right towards them. Sonic and Tails both fly away without the skateboard. Tails pulls free and goes after it, leading Sonic to run after him. Tails grabs his skateboard, and Sonic pushes him away just as the Zapper shoots him, changing him to stone. Tails runs back and tries to save him, but Sonic simply falls over. Tails starts to cry, where Grounder gloats over him, until Scratch joins him. Tails tries to push Sonic away, but Scratch grabs him and tosses him away. The two Badniks fight over who will get their credit. They then begin to do tug-of-war with him. Tails gets to the Zapper, and grabs their attention. Grounder tries to escape, promptly being blasted and changes to stone, but then (due to a mistake of Tails') changes back. Scratch and Grounder chase Tails, who tries to blast them, though he keeps missing. Tails hops on his skateboard, drives over, and picks up Sonic, to the anger of the Badniks. Grounder's phone rings again, and they answer Robotnik again, rather slowly. However, too scared to speak of their mistake, they pass the phone to each other without saying anything into it, to a point where Robotnik is infuriated.
Tails, while panting, has pushed Sonic the whole way to the top of a hill. He turns and looks down the hill, and sees that the Badniks are still chasing him. He pushes over a pile of logs that roll down the hill and chase the two Badniks. They get squished while Tails escapes with the still-frozen Sonic.
Robotnik appears and floats over Tails. Using a megaphone, he demands Tails to give him Sonic, which Tails ignores. He jumps through a vent, in which Robotnik attempts to follow through. However, due to his obesity, he is unable to do so.
Inside, Tails pushes Sonic on the skateboard around Robotnik's fortress, still being chased by the Badniks. He runs into a dead end down an alley, which the Badniks run right past. Tails spots a door and pulls it open, running through and closing it without the Badniks noticing. Inside, Tails wheels Sonic to an office. He stares sadly at Sonic, and attempts to wake him. It doesn't work, and Tails says that he will do anything to wake him up again. Sonic only falls down, and Tails walks towards the door, peeking outside. He looks out, only to see the Badniks right there; Tails slams the door shut again, leading Scratch and Grounder to crash into the door. They push against the door, but Tails holds fast, refusing to give up. Tails runs over to Sonic, and the Badniks go quiet, returning in a tank attempting to bust the door down. The whole place shakes, and Tails pulls Sonic over to a wardrobe to hide in, until he gets an idea. The Badniks crash down the door and a few machines as well, flying out and hitting the opposite wall. Tails comes over dressed as a police officer.
It fools both, but Scratch sees through it after noticing the apparent officers' two tails. Grounder objects to Scratch picking up an officer, and the two argue, giving Tails time to escape. The fox hides again, giving the two Badniks a plan to trap him. Tails follows Grounder around until he has a plan of his own. Grounder creates a chili-dog trap and hides with Scratch. Tails gets the trap to backfire on them while he steals the chili dog they used as bait and escapes. Seeing as his foot is stuck in the trap, Scratch orders Grounder to chase Tails. Grounder does so, but is trapped as well. They lie there for a few moments, until they try and grab Tails again, who activates the second part of his trap. The two Badniks get dumped on a stationary conveyer belt. They refuse to give up just as Grounder's phone rings. They once again inform Robotnik that they still haven't caught Sonic, but will freeze Tails with the Zapper.
Tails fetches Sonic on the skateboard and gets another idea. He polishes up a mirror laying around, where Scratch and Grounder arrive with the Zapper and shoot at a reflection of Tails. The beam hits Sonic, and he changes back, confused of what had happened. Scratch and Grounder are amazed that Sonic's out of the petrification. The hedgehog speeds about too fast for the Badniks to zap him. Sonic bends the Zapper lens to point at itself, because as soon as the Badniks use it, it changes itself to stone. Grounder hits it, making it explode and sending the two flying. Robotnik comes storming in at that moment, where the Badniks land on him. Tails activates a claw that picks up all three of them. He releases them over a crate of Quick-Drying Cement that gets wet from the fire sprinklers due to the Badniks' short circuiting form the cement's dust. They plunge into the cement, and start to splash all around. Sonic and Tails leave the fortress as Robotnik screams, "I HATE THAT HEDGEHOG!" Sonic tells Tails that he's proud of him for his actions and they high-five.
Dr. Robotnik introduces the "Ultra Freeze-O-Matic", announcing his plan to freeze every citizen on Mobius and install "Servitude Chips" into the frozen citizens, causing them to completely and unquestionably obey Robotnik, with a test run on Scratch and Grounder proving successful. Meanwhile, at Mount Splatterhorn Sonic and Tails are getting some rest and relaxation when a blizzard suddenly hits the area. Dr. Robotnik discovers that Sonic is at Mount Splatterhorn and demands Scratch and Grounder to capture him. After a lengthy ski chase, Scratch and Grounder fall a considerable height and suffer a blow to their heads, causing their Servitude Chips to malfunction. Sonic takes this opportunity to fool Scratch and Grounder into believing that he is their master as to learn Robotnik's current plan. Sonic then commands the two robots to take him to the Freeze-O-Matic to make a few "adjustments". Robotnik learns of this, believes that Scratch and Grounder have turned traitor, and decides to bury them all with the Ultra Freeze-O-Matic's "Avalanche Activator".
Sonic is able to use the fire from the friction his speed is creating to convert the falling snow into water, allowing him and the group to continue their mission. Meanwhile, Robotnik whips out his "Servitude Chip Remote Regenerator" and uses it to return the robots to his control. Scratch and Grounder, now under Robotnik's command, trick Sonic into crossing a thin ice bridge and capture Tails after the bridge breaks. Scratch and Grounder return to Robotnik's bunker with Tails, on which Robotnik tests the "Servitude Patch", a Servitude Chip designed to work on living, breathing creatures rather than robots. Tails, now under Scratch and Grounder's control, lures Sonic into the clutches of the two robots, but Sonic easily tricks Scratch and Grounder into commanding Tails to remove his own Servitude Chip, and escapes himself. Robotnik decides to dispose of Sonic himself, using numerous weapons built into the Ultra Freeze-O-Matic. Sonic soon disposes of Robotnik, tossing him into Lake Splatterhorn and using the Freeze-O-Matic's "Frozen Concentrate" feature to freeze the lake. Mount Splatterhorn mysteriously thaws during this time.
