He is one of the main characters in The Little Mermaid (film), it's sequel, It's Prequel film and TV Series. 


Sebastian the Crab, a sidekick for The Little Mermaids main character Ariel, is a character developed solely for the film, and is not derived from the original Hans Christian Andersen story. According to the Disney website, official novelization and Disney-sanctioned reference material, Sebastian is a crab.

Sebastian was conceived as a musical character for The Little Mermaid, and performs 2 songs ("Under the Sea" and "Kiss the Girl") that went on to become hits for Disney and were nominated for "Best Original Song" at the 1990 Academy Awards. Voice actor Samuel E. Wright's singing style and the compositions by Howard Ashman and Alan Menken for the Sebastian character lean heavily to calypso and reggae influences.


Sebastian is the king's royal court composer and holds a rather passionate love for music. While usually carefree, Sebastian is often seen to be very grumpy and worrisome. This is mostly due to Ariel's stubbornness who he is found with regularly. He is also prone to having panic attacks and fearing King Triton will murder him if he slips up on a task. Like the other sea inhabitants, Sebastian holds a great fear of the sea king King Triton. Despite the fear, he still shows great respect and they are obviously on good terms friendship wise. When scared, Sebastian's voice tends to become humorously higher in pitch. He can be sensitive at times about his size and the fact that his tiny arms prevents him from swimming as fast as Ariel and Flounder. This makes it difficult to tag along on adventures which is why he'll just grab onto Flounder's tail fin. Despite his size, the enemies of the kingdom, notably Ursula, still find Sebastian to be a big enough threat to foil their plans. Being part of the royal family, Sebastian is fairly intelligent and knows mostly all secrets of the sea, even more so than King Triton.

The Little Mermaid (film)

When the film opens, Sebastian is announced as being the "royal court composer", and conducts a concert that King Triton's seven daughters are supposed to perform in. Ariel, the youngest daughter, fails to show up for the concert, and later Sebastian joins King Triton in scolding her, blaming her for his humiliation. King Triton, worried about Ariel, tasks Sebastian with following Ariel and keeping her out of trouble.

Sebastian tries to do the job given to him, and is horrified when Ariel saves the life of and falls in love with a human. Sebastian accidentally lets this information slip to King Triton, who confronts Ariel and furiously destroys her grotto filled with her personal treasures. Feeling guilty for having "betrayed" Ariel, as well as being appalled with Triton's actions, Sebastian willingly follows Ariel when she visits Ursula  the sea witch for help, and later becomes an adviser in her quest to win Prince Eric's affections.

In the film, Sebastian starts out in a parental, supervisory role over Ariel, and over time becomes her close friend.

The Little Mermaid 2 : Return To The Sea

Sebastian is tasked by King Triton to watch over Ariel's daughter, Princess Melody, repeating his role from the original film. As he is hiding in a pink ribbon, Melody grabs it by tying it up in a bow accidentally gagging him when she is getting prepared for the party. He becomes a close friend of hers and he often tries to clam her down when she proves to be angered and frustrated. Sebastian is the first to learn about Melody's disappearance and joins Ariel and the now grown-up teenage Flounder to find her. During the final battle, Sebastian battles Clock and Dagger and after peace is restored he celebrates alongside the others as land and sea can now finally live in peace and harmony.

The Little Mermaid 3 : Ariel's Beginning

In the 2008 prequel, Sebastian is King Triton's attache, and is initially shown as being a strict enforcer of the sea king's rules. All music has been banned from Atlantica, but it is later revealed that Sebastian has been secretly performing music as the leader of The Catfish Club Band, which performs in an underground club. Technically this makes Sebastian the first character in The Little Mermaid universe to break a major law of Triton's.

When the underground club is revealed to Triton, Sebastian is placed in jail with the rest of his band. Thanks to Ariel, they manage to escape. As part of a premeditated plan, Sebastian leads them far away from Atlantica to a specific spot where Ariel finds her mother's discarded music box. Sebastian wants music to return to Atlantica, and he returns with Ariel to convince Triton to change his mind. When the film ends, music is restored to Atlantica, and Sebastian becomes the "royal court composer", setting up his role in the opening of the original film.

According to this film, Sebastian is the eldest of Ariel's friends, having been present since she was a small child all the way to her own parenthood in The Little Mermaid II: Return to the Sea.
