Po practiced his kung fu skills in the Training Hall with orders given by Shifu to make it across the obstacle course in ten seconds unscathed. Po was jumped in a sneak attack by Monkey, who was about to beat Po in their score-keeping, when Tigress suddenly interrupted them with a loud sneeze, to which she promptly fell into the obstacle course and caused the three of them to fly out onto the other side. Po and Monkey then joked around with the "sneezy trick", making light of Tigress's cold-like symptoms. She openly denied having a cold, and it was discerned by Shifu that she actually had River Fever. Po then convinced the Masters not to worry, stating that he once had River Fever as a kid and it went away the very next day. However, Tigress never had river fever as a cub. Unfortunately to Po's shock, Crane revealed that getting River Fever as an adult was fatal and that the only cure was tea made from the sacred sun orchid, located in the Valley of the Scorpion. In addition, the flower must be consumed before sundown or else Tigress would die. Monkey and Po set off to retrieve it while Tigress was reluctantly placed in a sick ward with sick children and Mr. Ping as entertainment, much to Tigress' dismay.
Upon entering the valley, Scorpion trapped Monkey unexpectedly and stung him with her elixir-enhanced, mind-controlling stinger, ordering him to set out to destroy Po. Po managed to escape Monkey's attempts to destroy him, not realizing that he was being manipulated, and took it as a friendly session of sneak attack training. However, Po soon realized the truth and eventually became cornered by Monkey, and hung on to a cliff, about to fall to his death. But thanks to the "poison of friendship", Monkey overcame the mind control and they both set out to fight Scorpion. They eventually defeated her (thanks to Po's unexpected sneak attack he had learned from Shifu), retrieved the sun orchid, and then quickly rushed back to the Valley of Peace, arriving at the Training Hall just before sundown. With no time to make the tea from the sun orchid Tigress consumed the orchid and nothing was happening. Everyone looked down sadly, believing she was dead. But she then jumped up and was immediately cured, and Po and Monkey continued to joke and try to outdo each other, with Monkey declaring a point as he tricked Po into putting peppers in his eyes.
While walking through the village street, Master Shifu explained to Po, Tigress and Mantis the importance of making sure that Princess Mei Li gets to the Qidan Clan safely. Po became excited after hearing the princess was only a kid, commenting that the mission will be easy. However, when Princess Mei Li finally arrived, she was shown as stubborn and spoiled. When Po attempted to introduce himself to her, she prodded him with her staff and caused it to break. She immediately blamed Po, but when he claimed that she had broken it, she demanded that he be executed by beheading. The execution was called off after Shifu respectfully explained that he was the Dragon Warrior. Po placed a bet with Tigress and Mantis that he could get the princess to like him by the time they arrive at Qidan, wagering against a foot massage. Both masters happily agreed. Po immediately began his first attempt by making a puppet for the princess. But she instead used it as a temporary replacement for her staff, hitting Po and the others over the head with it. The gang soon left the Valley to head for Qidan, but not before secretly being spotted by a gang of crocodile bandits.
Mei Li complained throughout the entire journey. She eventually began throwing fire poppers at Tigress, Po and Mantis, much to her amusement and to their discomfort. Whilst taking a break to eat and rest, Po tried performing juggling tricks on stilts, to which the princess simply knocked him off. Po later dressed up as a clown in another attempt, but before he could perform, Tigress sensed something and commanded the group to stop. The princess was annoyed at Tigress for this, but her servants then noticed the crocodile bandits surrounding them.
Po, Tigress and Mantis worked together to fight off the bandits. Princess Mei Li, on the other hand, was oddly unaware of the danger they were in and constantly interfered with the Kung Fu trio's fighting by demanding rice balls stuffed with lots of bean paste. Though Po, Tigress and Mantis succeeded in protecting the princess and her servants, the bandits had escaped with the group's valuables, including the food. Selfishly, Mei Li used the last of the water to clean her dusty crown and started blaming Tigress and Mantis for the loss of her valuables. Though the two accepted this, Po, finally having enough of this, defend his friends and calls the princess mean, bossy, and selfish. He stated that no one liked her and that the bandits wouldn't have taken the valuables if she hadn't interfered during the fight in the first place. At that point, the princess's anger faded and soon ran off crying, and Po feels very guilty for saying such harsh words, though Mantis comforts him that he was being honest in general. Tigress then declares for the whole group to camp out for the night.
That night, Mei Li sat away from the group. Po, feeling guilty for his earlier actions, sat next to her and told her about a story of a panda who just wanted to make the princess happy. Afterwards, the princess went over to Po and handed him the fixed puppet she had broken earlier, apologizing for her previous behavior. She stated that she never had any real friends before. Po then offered to be her friend, to which she accepted and the two happily sat down to play a game of mahjong.
The next morning, the two were seen laughing together as Po carried Mei Li around, holding his ears and steering him as he ran aimlessly around. The travelers soon arrived at the Qidan clan's territory. As Mei Li went ahead to approach the Qidan king, one of her servants relayed to Po, Tigress, and Mantis that she is to become a sacrificial slave to the Qidan king in exchange for peace, as the king receives many princesses during the ages and none of them have lasted for long as they've endured too much painful labor working for him. Realizing that Mei Li will suffer the same fate, Po and the others quickly followed her inside.
The clan's king immediately demanded to see the princess. In a desperate attempt to spare Mei Li of what will come to her, Po pushed Tigress forward and stated that she was the princess. Though Tigress hesitantly went along with it, the king then demanded that she sing the "Ceremonial Princess Dancing Song". After Tigress gave a poor performance, the king became angry and once again demanded to be handed the princess. Po, Tigress and Mantis refuse and soon fought the warriors, but Mei Li gave herself up. In a bid to save her, Po then offered the king a deal: If he won a fight against any of the king's warriors, the princess would be free to go; but if he lost, the king would claim him, Tigress, Mantis, and the princess. The king initially refuses, but after learning that Po is the Dragon Warrior, he accepted and placed himself up for battle, proclaiming himself as the legendary warrior Temutai.
Po's kicks and punches had no effect on the buffalo and he was tossed around constantly. During a brief interval, Mantis stated that he couldn't beat him Panda Style, and after some encouragement from Mei Li, he claimed Princess Style. Getting on top of Temutai's head, Po grabbed the warrior king's ears and guided him into rocks and walls before running him into the clan's old stone podium where they would keep the princess servant chained. Temutai admitted defeat and kept to Po's deal: He let the princess go, vowed to keep his promise of peace, and as a bonus also catered to the group with fried rice balls.
The princess, Po, Tigress and Mantis left the Qidan clan's village and began their journey home. Along the way, they stumbled upon the Croc Bandits, who were arguing about the material they stole. However the three warriors are flying in to attack them.
In the barracks' kitchen, Po and the Furious Five were eating, while Mantis was sulking about his girlfriend dumping him. To cheer him up, Po made some of his famous sticky dumplings, consisting of bean paste dumplings, honey, (extra) sticky plum sauce, and Po's secret ingredient (which, as Crane noted, was actually "what they patch walls with"). Even though Mantis accepted the offer, he ended up getting stuck on the dumpling itself. Shifu soon walked in and declared that it was time to train. The Five immediately followed behind while Po went back for his dumplings first.
After a training session in the Training Hall, Shifu dismissed the Five and assigned Po to clean the entire Hall by sundown as punishment for eating in the Hall. But before cleaning, Po decided to do some actual training first. However, the stickiness from his dumplings was all over his hands, thus getting him stuck on one of the swinging clubs. Po's struggle to free himself only resulted in the clubs' chains breaking and falling from the ceiling. While dodging the clubs, Po dived into the Jade Tortoise of Wisdom, sending his bowl of dumpling flying into the air and landing in the gears of the Training Hall's machinery. The dumplings caused the gears to jam and the Hall fell apart, much to Po's horror. He desperately (to no avail) tried to fix it before Shifu found out, but then he noticed a sign on the wall that indicated the marks of Shifu and Taotie. Realizing Taotie helped make the Training Hall, Po set out to find him.
Upon finding Taotie's house, Po fell prey to several booby traps, one of which was a dart that knocked him out into sleep. When he woke, he saw a teenage warthog (Bian Zao) in front of him. Po asked for Taotie, and the warthog called for his dad. Taotie appeared and started hitting Po with a staff. Po explained that he was the Dragon Warrior and that he needed Taotie's help. Thinking someone may find out about this, he made up a lie by saying Shifu had asked for Taotie to fix the Training Hall. Taotie was furious that the Training Hall was broken, but agreed to come and help, promising that Shifu would not be told.
After knocking Po out with another dart from his traps, Taotie then revealed to Bian Zao that he and Shifu were only former friends. They had trained together many years ago at the Jade Palace, but Taotie was never as good as Shifu. To improve their fighting skills, he and Shifu built the Training Hall together, but it only helped Shifu improve greatly and still left Taotie as a clumsy student. Taotie tried to make up for his weak spots by using his mechanical skills to create a giant wooden warrior, but when he showed it to Oogway and Shifu, they were horrified and told him his machine "sullied the purity of kung fu". Taotie was dismissed from the palace and had been hungry for revenge ever since.
Po snuck Taotie and Bian Zao into the palace by carrying them in a crate. When he saw the Training Hall ruined, Taotie was clearly heartbroken and angry. He calmed down long enough to trick Po into bringing him the Jade Orb of Infinite Power, which he planned to use to get his revenge. Po retrieved the orb and quickly returned to Taotie, who then instructed Po to keep everyone out of the Training Hall. With some difficulty, Po succeeded in doing so. However, Shifu and the Five grew suspicious of Po's behavior and confronted him about it. While Po desperately tried to cover it up, the wall of the Training Hall suddenly burst and they were all thrown back. Taotie and Bian Zao emerged in a giant wooden warrior made up of the Training Hall's equipment, powered by the Jade Orb.
Shifu recognized Taotie and was shocked, demanding to know how he got into the palace. Taotie gloated in telling them that Po had led them in, to which Po quickly tried to explain the situation with the dumplings and how he thought Shifu and Taotie were friends. However, Shifu corrected him by saying Taotie's heart had turned dark and they ceased to be friends. Furious with Po, Shifu dismissed the panda in helping them stop Taotie. Po ran off, ashamed. Shifu then ordered the Five to attack. The quintet quickly disabled some of the weapons on Taotie's machine. However, Taotie gained the upper hand when he finally captured the Five in traps and tossed them aside, leaving only Shifu to fight Taotie. Shifu was able to fend off most of Taotie's attacks, but in one moment was caught off-guard and Taotie captured him. He taunted Shifu, saying machinery was more powerful than kung fu, but Shifu refused to give up and declared that "machinery will never be more powerful because it has no heart." Taotie gave one last taunt before pulling a lever to finish Shifu off.
It just then that Po showed up with a wok on his head and a bowl of sticky dumplings in his hands much to Shifu and Taotie's surprise. Taotie attacked, but Po's technique proved to be successful as he used his sticky dumplings to glue the machine parts together and rescue Shifu. When he ran out of dumplings, Po managed to hold of Taotie's attacks long enough for the machine to malfunction and break down. Instead of fighting, Taotie used his spinning contraption as an umbrella to escape with Bian Zao. However, the blades suddenly stopped working and the two fell to the ground hard before fleeing.
Po apologized for his mistake, but Shifu only congratulated Po on saving him and the Five. Shifu went on to say he had one more job for the Dragon Warrior, and then promptly held up a broom for Po. Po groaned, but went on to clean. That night, Po and Mantis shared a bowl of sticky dumplings. Mantis seemed to be much happier, and Po comforted Mantis about his girlfriend dumping him. However, Mantis reveals that they got back together again.
As Po daydreams where he imagined him and Tigress as heroic partners on an important mission to retrieve a special statue. Tigress suddenly broke it off, annoyed about him daydreaming out loud. The mission in Po's daydream had been true: Po and Tigress were assigned to bring back a statue of Master Oogway to Shifu after having it recently cleaned. Po tried to make conversation with Tigress along the way, which only made her more and more angry. While urging him to stop, they accidentally drop the statue off from its caravan. They tried to keep it from falling, but were then caught by surprise when the Croc Bandits suddenly chain their hands together. They all engaged in a fight, but quickly found it difficult to do so with their hands chained together. The bandits push them towards a ledge, and in a desperate attempt to escape, Po jumped off the ledge, dragging Tigress with him.
They both made it to the ground safely, but Tigress was furious for losing the statue, as well as the ruby the bandits wanted. A proud Po then showed her the ruby he had snatched while the bandits were fighting. Knowing the bandits will soon be after them, Tigress began to run dragging Po behind her. Back at the statue, Fung was surprised to see the ruby gone. At first, he thought it was a joke, but then became angry to hear that Po took it. Furious about this, he ordered the other bandits to go and get it back.
While Po continued to try and talk to Tigress, she was desperately trying to find a way to get the chains off. Po had an idea, but it ended up backfiring and hurting Tigress. Before they could try something else, the bandits found them and began to chase them. The two ducked behind a rock to lose them, but were found only moments later. The two ran for cover on a hill and escaped into a walled-off garden, to which Tigress quickly blocked the entrance. Seeing a large bell in the middle of the courtyard, Tigress gets an idea on how to cut the chain. Po nervously stands under the bell while Tigress dropped the bell on top of him. Disappointed to see the chain was still not cut, she released a very shaken and a slightly deaf Po. He began yelling which caused them to be discovered once more. Before the bandits could break into the garden, Tigress quickly thought of an escape: She took the chain and swung Po around, using Po's weight to gain momentum and break through the wall. The two escaped and Fung became even more furious.
Back in the forest, the two found shelter by a tree. Tigress noted her hunger, which still made her angry at Po for having eaten her lunch earlier. Po tried to make it up to her by climbing the tree to retrieve an apple, but he slips and falls, pulling Tigress along. When on the ground, she was about to yell at Po again when she suddenly saw that she was holding an apple. Humbly, she thanked Po. The two eventually build a campfire and Tigress started crafting a wooden key while Po ate some honey from a tree. The two were getting along until Po asked her if she had wanted to be the Dragon Warrior. She admitted that she did, and Po comments that he knows she thinks Oogway made the wrong choice, to which Tigress doesn't reply. When Po placed wood into the fire (accidentally included Tigress' wooden key), she finally lost it and said she thinks Oogway did make a wrong choice. Insulted, Po walked away. He then realized along the way that he had slipped out of the chains with the honey and starts running back. But meanwhile, Tigress was sulking by the fire and felt something tugging the chain. She thought it was Po, but suddenly she was yanked and dragged away by the Croc Bandits. Po returned and was horrified to see Tigress was missing.
Tigress was tied up and confronted by Fung, demanding to have the ruby back. Tigress refused and kicked Fung when he got too close. Fung became annoyed by this and had a large machine rolled out from the forest. When the machine rolled out the wrong way and Fung tried instructing his bandits to fix it, Po located them and threw rocks at the bandits as a distraction. They spread out in alarm, and Po immediately ran out an untied Tigress. While escaping with the statue, the bandits surrounded them. They all engaged in a fight, but they were overwhelmed by the number of bandits. By Po's suggestion of a plan involving them working together, Tigress chained them together again and they worked together to fight off the bandits. While they fought, Fung had seized possession of the statue and the ruby and started driving away on the machine. Po and Tigress chased after him, eventually catching up to him and working together again to break his machine and stop Fung's escape.
The two smiled at each other afterwards and congratulated each other. Tigress told him Oogway had made the right choice and respectfully bowed to him. Po was touched by her words. The two carried the statue away into the distance while Po started the same conversation they had at the beginning of the episode.
In the barracks, Po is excited: he was finally going to learn new techniques from the sacred scrolls. Unfortunately, his excitement is cut short when he sees that the first scroll only talks about how to make tea. Po tries to skip ahead, but Master Shifu stops him, explaining the importance of reading the scrolls in the proper order. Shifu sends Po to the Hall of Heroes to study. Meanwhile, Taotie plots his revenge after his recent defeat. His anger is flared even more when he receives mail from the Jade Palace: a bill for the destruction of the Training Hall.
Back at the palace, Po feigns excitement over learning tea, but soon gives up and opens a different scroll. In it, he discovers the Fluttering Finger Mindslip, a technique that, if done correctly, erases one's short term memory. Po tries the technique and accidentally performs it on Viper, who freezes as she is affected. When she unfreezes, Viper tries to tell Po something, but cannot remember and leaves. Po tries it again on Crane when the avian tells him it's his turn to sweep the barracks, and the technique proves successful. Po, excited over his new skill, began to abuse the power by using it whenever he was going to get in trouble by the Furious Five.
Everything seems fine until lunch, when the Five suddenly attack Po. As he defends himself, Po realizes that they have no memory of him and still believe that the Dragon Warrior has not been chosen. In a desperate attempt to stop them from attacking at once, Po performs the Fluttering Finger Mindslip technique on each of them and sneaks off. He then finds out that he fully erased their memories by mistake and rushes off to fix it. Unfortunately, Po has lost the scroll he learned the technique from. Shifu comes by as Po searches, and Po is forced to admit what had happened. When Shifu got angry, Po reflexively abused the Mindslip again; he told Shifu what happened again, but also added on that Shifu had already punished him. Shifu leads Po down to the Cave of Mysteries, where they can hopefully can find an antidote.
Meanwhile, the Five have wandered off and arrive in the Sacred Hall of Warriors. All they know is that they have good fighting skills and decide they're dangerous bakers. Taotie spots them, and then he and Bian Zao pilot a giant bamboo bird machine over to the Five, with the intent to ambush them. By then, the bird crashes. Taotie angrily confronts the Five about the bill, but finds that they have no recollection of who he or they are.
During this, Po and Shifu have arrived at the Cave of Mysteries, which holds scrolls 51-10,000. Luckily, they find the scroll they need on the first try and discover the remedy for the Mindslip: covering the head with clay from the Alabaster Pot of Remembrance. However, the pot can only be found at the end of the Corridor of Unbelievable Agony, which Po must travel down. Shifu leaves him to do so while he goes to find the Five.
Taotie was still confused why the Five didn't know him, but when they ask if they knew who they were, he uses it to his advantage. Taotie told the Five that he was their kung fu master, gave them ridiculous names, and told them Shifu and Po (whom Taotie called "Shifu's-An-Idiot" and "Po-Chews-With-His-Mouth-Open") were their mortal enemies. Shifu bursts in suddenly, and Taotie orders the Five to attack him. The Five obey, fighting Shifu upon Taotie's orders. Shifu tries to get them to come to their senses without hurting them, but to no avail.
In the Cave of Mysteries, Po only skims over the scroll before blinding running into the Corridor of Unbelievable agony. The corridor's traps are set off as Po is slapped, burned, and shot with darts. He gets to the pot, but finds out that he forgot about the key to unlock the cage. He runs back through the traps, grabs the key, and runs back, only to find that there was a second key to turn off the corridor's defenses.
Back in the Sacred Hall, Shifu deflects and tosses aside the Five as they continue to attack him. Taotie gloats over his supposed victory, until Po arrives with the Alabaster Pot of Remembrance. Taotie orders the Five to attack Po, and they obey, but with Shifu's help, Po manages to get clay from the pot on the Five's heads without hurting them, helping them regain their memories. Taotie flees with Bian Zao in their bamboo bird, vowing that he will return for revenge and that he wouldn't pay the bill.
That night, Po explains what had happened and what he had learned from the experience. He then promises to never use the Fluttering Finger Mindslip or be lazy again. To prove it, he uses the technique on himself. But his memory is erased too far back, as he acts as though he just met the Five.
In the Noodle Shop after Monkey had played a joke on Po with his "joy luck buzzer" which he intended for Tigress, the panda left after being called "gullible" and came into a nearby of the Bamboo Forest, where he accidentally fell in a deep hole. All his attempts to pull himself out of the hole were useless. However, Fung arrived and pulled him out with a rope. Once out Po suspiciously thought that the Croc bandit wanted to rob him, but the latter said he just wanted to help, and the two departed from each other.
Later, Po returned to the Jade Palace and met Tigress and Monkey. He told them about his encounter with Fung, after which they let him know how they wouldn't have been so sympathetic with the outlaw. Shortly after, Fung arrived at the Palace and sought help from Po, without the others knowing, and begged him to help in the search of his brother, kidnapped by Jong.
Po eventually accepted, and they began their search from the bamboo forest. After they walked for a while, they found Jong's territory and, while they were irrupting through the guards' station in the border of the area, Fung was immediately very reluctant to fight, letting Po fight for him. After the latter had finished fighting, he discussed with Fung about why he let him do all the fighting. The crocodile, with the excuse of being the leader of the expedition, convinced Po that he was under pressure due to his role.
Later they reached the fortress of Jong, they burs into the cell where Po thought Fung's kidnapped brother was held. The latter grabbed a box, saying that his brother would have fitted inside it, and fled. Once out, they escaped from the prison. However, what Po didn't know was that Fung had tricked him, and they hadn't gone to save his brother, but to kidnap Jong's son, whom Fung planned to use to blackmail his father. Once returned to the Jade Palace, Po was approached by some of Jong's guards, who arrested him for the crime of kidnapping.
Po was brought back to Jong's fortress and chained in the prison. There he explained to Jong himself about what had happened and that Fung had fooled him. Jong was unconvinced, and was about to torture the panda with a weapon when Fung arrived to rescue Po. He explained that he had organized the kidnapping, not Po, and he gave Jong his son back. However, Jong merely wanted both him and Po to pay for the incident, and attempted to have them captured. Po and Fung managed to escape from the dungeon and then from the palace.
After they had run a great distance, Po told Fung that he had to bring him in jail for the kidnapping. The crocodile, though outraged at first, acted out that he would comply before Po fell in the same pit from before. Fung then said his farewell and ran off, this time leaving Po trapped.
Po and the Furious Five's yoga lesson was interrupted when Zeng brought Mantis an urgent message. After Master Shifu removed the tiny scroll from it's encasing and handed it to Mantis, he was shocked to read that his ex-fiance Hao Ming needs him to urgently return to their hometown. Po and the Five insisted on coming with them (especially Po, who was surprised and excited to learn that Mantis had almost been married), but Mantis unexpectedly became nervous and refused, giving the excuse that his hometown did not like tigers, snakes, monkeys or cranes. Once Mantis had departed, Shifu ordered Po to follow him, just in case he needed backup. For the next couple of days, Po quietly followed Mantis on his journey, but was eventually caught. Though Mantis was angry at being followed, he was nervous and reluctant to have Po visit his hometown, and tried to persuade him to go back home. However, they had already arrived at the gates to the village. Horrified, Mantis confessed to Po that long ago, Hao had jilted him and left him broken-hearted, so Mantis decided to get back at her. Before he could explain exactly what he had done, the villagers suddenly rushed out in excitement towards the two friends, intending to greet the Dragon Warrior. Thinking that Mantis had told them that he was coming, Po gladly welcomed the villagers... but received a shock when they greeted Mantis instead and carried them into their village.
During the villagers' celebration, Po snuck into the village square and confronted Mantis, demanding an explanation. Mantis confessed that in order to make Hao regret jilting him, he told everyone that he was the Dragon Warrior. Mantis promised to confess the truth once the celebrations were over, but Po, deciding to support his friend, instead suggested that Mantis keep up the facade in order to rub Hao's nose in it. Po proceeded to disguised himself as Mantis's crippled sidekick, complete with an eye patch, crutch, and a habit of making weird noises and slamming his head on the table.
During a celebratory dinner, Hao and Mantis reunited at last. While Mantis remained cold, Hao attempted to seduce him, revealing that she had summoned Mantis back to his village in order to get back with him. Po was soon asked how he had come to be Mantis's sidekick. Thinking quickly, he conjured up a story about being a former dirt farmer who was saved by Mantis from a rock monster. One eye closed forever from witnessing such 'awesomeness' (hence the eye patch) and Po begged Mantis to let him be his sidekick. Mantis decided to let him tag along. Much to Po's dismay, Mantis soon gave in to Hao's seductions, and once again became her boyfriend. However, at that moment Hao's very recently ex-boyfriend Dosu burst in. Angered that Mantis had "stolen" his girlfriend, Dosu and his whistling sidekick Sai So challenged Mantis and Po to a duel at noon.
The next morning, Mantis woke up in his and Po's room literally crazy with love, but Po quickly reminded him of their fight at noon. However, Mantis had already made plans with Hao to meet her parents, but promised to be at the fight. Before leaving, he made it clear that Po was not to fight them, otherwise the ruse may be discovered. When noon arrived, Po stood in the village square facing Dosu and Sai So... while Mantis was a no-show. Angered, Dosu and his sidekick brutally beat Po before informing him that the duel was rescheduled for two o'clock. When Mantis returned to their room later that day, he found a beaten and displeased Po. Po informed him about the new duel, but Mantis had once again made plans with Hao beforehand, but again promised to be at the fight at two. However, when the time came, Mantis once again didn't turn up and Po again received a beating. The same thing happened at six, and continued up until nine, when Po returned to their room badly beaten and now genuinely needing his crutch. Tired of Mantis's broken promises, Po declared that Mantis was a disgrace to the Dragon Warrior name and that tomorrow he would be returning to the Jade Palace. In a desperate attempt to convince Po to stay, Mantis revealed that he and Hao were getting married. A thoroughly shocked Po was opposed to this, stating that Mantis was needed at the palace. Mantis, still blinded by love, demanded to know why Po wouldn't support Mantis at this important event. Po retorted that all he had done was support him, but since Hao came along all Mantis has done was let Po down. Po then departed the village.
The next morning, Po was traveling through the forest, muttering about his ordeal. Annoyed that he had been unable to fight Dosu and Sai So, he proceeded to display his remarkable kung fu skills, felling several trees with one toss of his crutch. However, Po quickly spotted Dosu and Sai So staring at him in shock, having seen the whole thing. Despite Po's attempts to cover himself, Dosu figured out that Mantis was a fraud. He and Sai So rushed back to the village to reveal the truth to Hao Ming and give Mantis a severe beating. Po followed in an attempt to stop them.
Mantis and Hao's wedding was in progress when Dosu, Sai So and Po made it back to the village, and a scuffle ensued between the three as Po desperately tried to stop Dosu from revealing the truth. Po soon found himself being beaten up once again as Mantis and Hao exchanged vows. Hao revealed that ever since she learned that Mantis was the Dragon Warrior, she knew that she had always wanted to be "Mrs. Dragon Warrior". Mantis, seeing his friend in trouble and realizing that Hao only loved him for his faux title, left Hao at the altar and came to Po's aid. He and Dosu finally faced each other in combat, with Mantis victorious. However, Dosu was able to reveal the truth to Hao. Po attempted to maintain the facade of being an injured sidekick, but Mantis stopped him and revealed the truth himself to the entire village. The villagers were shocked, and and outraged Hao called off the wedding. Mantis couldn't care less, and Po informed Dosu that Hao was once again available, but Hao was less that happy to take him back. Mantis then proceeded (with extreme difficulty) to carry a still injured Po out of the village.
In the barracks kitchen, Po was seen trying to get his hand out of a pot it was stuck in. Then Shifu came in asking for the Furious Five, but with all of them out and busy, Shifu walked away with a distraught face. Po asked if something was wrong, then Shifu told Po about the Sacred War Hammer of Lei Lang, and about Tong Fo and the Five's dangerous battle with him. They defeated Tong Fo and kept the war hammer safe, but Shifu also mentioned that he just found out it was a fake, and he needed one of the Five to go undercover and retrieve its location from Tong Fo in jail by using a shift stone to change appearance. Po said he could do it without the Five, but Shifu insisted on waiting for them, since he said Po lacked subtlety, finesse, and cunning. Po got angry and took a shift stone when Shifu left to prove a point to him.
Po disguised himself as Sheng, a fugitive goat criminal, and turned himself in to the guards at Chorh-Gom Prison. He kept asking for Tong Fo while being escorted to his cell (much to the annoyance of the rhino guards escorting him), but after he was thrown into his cell, he shortly met Tong Fo. "Po/Sheng" (referring to his disguised form) commented on how big his eyes are, and Tong Fo merely stated that he just has a small skull. Po/Sheng tried to make small conversation with him only to be pinned to the wall by Fung and Gahri, claiming that Po/Sheng was not a good criminal and lacked finesse, subtlety, and cunning. Po/Sheng then admitted that he was the Dragon Warrior disguised as Sheng and threatened that if he's hurt, the Five will come after him.
This sounding so utterly ridiculous, Tong Fo dismissed it and settled down. After Tong Fo told Po/Sheng afterwards about where he hid the Warhammer (which he specified as Camelback Mountain), he went into the backroom to change back, only to be confronted by Fung and his gang again. They commented how they were the only "bootlickers" for Tong Fo, and began to attack him. Po/Sheng dropped the shift stone while he fought the crocs, and Tong Fo watched and was astonished, remembering how Po/Sheng said to his face that he was disguised as the Dragon Warrior. After Po/Sheng defeated the crocs, he locked Po/Sheng in the cell and used the shift stone to disguise himself as a rhino guard. Panic surged through the prison when the guards found out, but Tong Fo posed as a rhino guard and simply walked out the prison doors. Po/Sheng tried telling the guards about the situation, but ended up not believing him. He stole the keys from one of them and obtained the aid of the croc bandits.
After escaping, Po/Sheng went after Tong Fo and the rhino guards posted up a "Wanted" sign in the village. Tigress and Monkey were returning from their assignment and found the poster, commenting on how evil the picture of Sheng looked. Po/Sheng found Tong Fo, but was stopped by Tigress and Monkey. They began attacking him thinking he really was Sheng, but Po/Sheng tried to prove it was him and eventually succeeded. Afterwards, Tong Fo retrieved the hammer, only to be distracted by the crocs and engaged in a "hot potato" battle. Po defeated Tong Fo by jumping off with the hammer and throwing him off. The hammer fell in the hands of a small croc, who was actually Shifu with the other shift stone. He explained that he went after Po after he found out he took the shift stone so he could prevent Po from messing up. However, he then apologized, saying that without Po, they wouldn't have safely retrieved it. Po then accidentally tossed the hammer, which on impact destroyed part of the Camelback Mountain.
While the Furious Five were eating breakfast, Po stumbled in with an arrow through his head. As the Five gather round him in concern, Po revealed that he was wearing a trick arrow, much to their annoyance. He remarked that Tang the Toy Vendor had just came through town, and he bought as many joke items and toys as he could, among them a fake sword and a large kite. However, he had trouble unfolding the kite, and after much hardship and pain trying to get the kite to fly in the bamboo forests, it finally unfolded, and the wind was strong enough to carry Po himself into the air.
Grabbing onto his kite like a hang-glider, Po viewed the Valley of Peace from above. Suddenly, he noticed a commotion going on in the Jade Palace and descended to investigate. He found that the Qidan Clan had stormed the palace and was fighting the Five. Po took on Temutai and his warriors single-handedly. He then started spinning around, and unleashed a blast of green energy from his palm that expelled Temutai from the palace, sending him crashing into a mountainside (the buffalo announcing that their fight was a draw). Shifu, who had just returned and having witnessed this, asked Po when and where he had learned the Thundering Wind Hammer, one of the Seven Impossible Moves. Po answered that he thought he made it up, but Shifu recalled that there was one other who had mastered it. After seeing this move, the Five all refrained from physical contact with Po, even for a high-five.
Po expressed confusion and asked Shifu what was going on. Shifu showed him a painting of a previous incarnation of the Furious Five, which he was part of. Po noted an X painted over a female owl, who Shifu identified as Fenghuang, who had been the strongest of the Five, and who eventually turned evil. Therefore, when Po demonstrated the Wind Hammer, it was a sign that he, like all of the past most powerful warriors of the palace, would turn evil too.
Po anxiously went to Monkey's room to ask him if he really believed he would turn evil. Monkey explained that Fenghuang was specially tutored by Oogway until she became the most powerful of the Five. However, her pride and strength had corrupted her, and she challenged Oogway to a fight to determine who would be the master of the Jade Palace. Though Oogway had crafted an inescapable, owl-shaped cage, Fenghuang realized that she could not defeat Oogway after engaging him in a long battle, and fled into the Northern Mountains. Po only feared more of becoming just like Fenghuang. Trying to reassure his friend, Monkey stumbled, revealing a panda-shaped cage he had made. Po walked away, depressed.
Over the next few days, Po worried more and more, considering every small mistake he made was making him evil. Though Shifu tried to persuade him otherwise, Po wasn't convinced, and tossed away a scroll, causing the palace's dragon statue to crash and destroy the Moon Pool. After this, Po ultimately decided to leave the Valley so that he wouldn't hurt anyone once he turned completely evil. He said his farewell to the Five, his father, and left.
Po wandered far and wide until he reached the Northern Mountains. He was surprised when he saw Fenghuang, and accidentally fell over the mountainside. Fenghuang saved him and carried him to her cave. She could tell that he was from the Jade Palace from the hint of sandalwood incense that she disliked. When he admitted that he left the Valley so he wouldn't turn evil like her, the owl became curious, asking about Oogway. Po confessed that the tortoise was gone, news that excited Fenghuang. With Oogway out of the picture, she claimed that nothing could stop her from conquering the Valley of Peace. She then tried to entice Po to join her, but he refused, and the two briefly fought before Fenghuang left him in her lair, promising that he would join her, sooner than he thought. Realizing he had to stop Fenghuang, Po then came up with a plan to use Fenghuang's molted feathers to create a hang-glider to soar back to the Jade Palace.
At the Jade Palace, Shifu confronted Fenghuang, and much to her chagrin, had lit some sandalwood incense. Fenghuang then took on the red panda, as was able to best both him and the Furious Five. Before she could deliver the killing blow to Shifu, Po arrived, crashing in on his hang-glider, and he fought her. Fenghuang questioned his motivations, asking if he would really fight for friends who had wanted him gone. This caused Po to hesitate, but he resumed fighting, and used the Wind Hammer in their battle, only for Fenghuang to demonstrate how to deflect it. When she repeated the move back at him, Po copied her and deflected it. Recognizing the panda was a quick learner, Fenghuang again attempted to spur him on to the path of evil by showing him how to carve through solid jade and the Mongolian Fireball, and Po then seemed swayed by the promise of power. Shifu called for Po to not listen, but the panda moved to finish him off with a sword, resulting in Shifu rolling away and remaining still.
As Fenghuang gloated over their victory, however, Po sneaked up on her with the owl-shaped cage, suddenly trapping the owl. He then revealed that he had stabbed Shifu with a fake sword. As Fenghuang was shipped off to Chorh-Gom Prison, declaring promises of revenge, Mr. Ping welcomed back his son, glad that he hadn't turn evil. Po then figured that he had no reason to be concerned about becoming evil anymore, as it had only happened to the strongest of the Furious Five (telling Shifu to keep an eye on Tigress while she was within earshot). As the panda walked off, gobbling down a pot of noodles, Monkey asked Shifu if he should dispose of the Po-shaped cage. Shifu declined, saying better safe than sorry, but advised Monkey to reshape the middle of it.
After training outside the Training Hall, Po followed Shifu into a room where he wanted him to dust some artifacts. After being being impressed by some artifacts, he was drawn towards the Mystical Mirror of Yin and Yang. Shifu told him that it was a replica and the original one was kept in a sealed closet nearby, then he told him not to open it and left. Po couldn't stand the temptation and disobeyed Shifu's orders, as he gazed into the Mystical Mirror of Yin and Yang and separated his bad part from himself, but Po didn't notice that he had split into two Po's. He then heard Shifu calling him, immediately closed the closet and left the room.
Shortly after, his bad "ego", aesthetically identical to him, went out from the mirror and began to wander. Meanwhile the good part of Po went to Tigress, Monkey and Mantis, who were having lunch. He was very kind with his friends by giving each one of them a pair of grass slippers, that he had made, and offering to wash dishes. Subsequently Good Po and the others went to defend the Valley against Fung and his croc bandits. During the counterattack Tigress and Monkey noticed that Po was behaving strangely, as they didn't know what they thought was Po was actually only his good part.
Crane in the meantime, remained in the Valley along with Viper and Mantis, returning to the Jade Palace where he met Bad Po and, naturally thinking he was the usual Po, said to him that Shifu wanted to see him and the Furious Five in the Training Hall. But Bad Po responded with an insult.Shortly after, Crane, on his way to the Training Hall, bumped into Good Po. Crane thought he was the same Po whom he had previously encountered and, annoyed by the previous insult, beat him, not knowing that there was two Po's.
Later, Bad Po went to the Valley, frightening and insulting all the citizens who he met; consequently when Good Po decided to walk around there he was shunned and mistreated by everyone due to all the crimes Bad Po done to the population, but without understanding why they were doing so, because he didn't know about his bad part.
Finally the two selves met and Bad Po persuaded the other one, taking advantage of his gullible nature, to cooperate with him. Bad Po imprisoned Good Po in one of the Ancient Locking Stocks, located in the same room of the Mystical Mirror, and then he left.
Bad Po in the Training Hall with Shifu and the Furious Five, continued to behave arrogantly and disrespectfully with all of them. Then Shifu, while meditating alone in the Hall of Warriors, was able to understand that Po had looked into the Mystical Mirror of Yin and Yang, and had split into two parts, but at that moment Bad Po, who had snuck behind him, captured and locked him in the locking stock next to Good Po.
While they were detained Shifu told Po’s good part that if he would remain separated from his other side until sunset, then the split would have been permanent and Bad Po would be unstoppable.
Meanwhile, Bad Po coalesced with Fung and the croc bandits planning to invade the Valley, but at that moment Shifu and Good Po were already free. Indeed they had never been imprisoned, because the stock wasn't locked, so he had stayed there only because Bad Po told him to. Once Good Po freed Shifu they advised the Five of the incident and organized a plan with them.
When Bad Po entered in the Jade Palace, the Furious Five tried to get him to look into the Mystical Mirror, Bad Po overheard that if this mirror would break then he would stay there forever, eventually the Five managed to get him to look into the mirror, but Bad Po was able to break it before it could take its full affect.They were using the fake mirror and Good Po had the real one. As Bad Po broke the fake artifact, he didn't noticed Good Po with the real one behind him. When Bad Po turned around he faced the real mirror and the two Po's merged, turning into the normal Po.
