Horatio Thelonious Ignacious Crustaceous Sebastian Crab is a red crab and the tritagonist in Disney's 1989 animated film The Little Mermaid, its 2008 prequel film, its 1992-94 television series and its 2000 sequel in the sage. Sebastian is a sidekick for Ariel.

He has been voiced by Samuel E. Wright, Kevin Michael Richardson and Philip Lawrence.


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.


The Little Mermaid

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 her 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 Prince Eric. 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: The Series

Sebastian appears in every episode of the prequel television series, which follows the adventures of Ariel when she is still a mermaid. In the series, Sebastian's occupation is King Triton's assistant, adviser and confidant. Sebastian is shown as being a good friend of Ariel and Flounder, as well as Urchin, a new character unique to the television series. He is sometimes strict and often critical of Ariel's adventurous ways, but often ends up going on her adventures with her.

In one adventure, in the episode "Island of Fear", he accompanies Ariel as she tries to find the source of a pollutant that is sickening the fish. He befriends a human boy named Daniel, and helps the boy to escape from the evil scientist the boy is forced to work for. This makes it one of the few times in the series that a character directly interacts with a human.

Throughout the series, Sebastian's character is further developed via dialogue and entire episodes dedicated to him. In the series, Sebastian is said to have come from a large Jamaican family. In "King Crab" his parents visit him, and it is revealed that he had lied and told them he was the King of Atlantica. In the episode "Tail of Two Crabs", Sebastian has a rivalry with another crab named Zeus, and they both try to one-up the other. According to dialogue in this episode, Sebastian was born in Jamaica and went to Music Academy in Trinidad prior to joining King Triton's staff as his assistant. "Tank You for Dat, Ariel" reveals that he is some what insecure regarding his size.

The Little Mermaid II: 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 calm 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 adult Flounder to find her. During the final battle, Sebastian battles Cloak 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: 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 oldest 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. There is also evidence in the second film, by the time Melody is 12 years old, Sebastian has already become an elderly crab in terms of age.

House of Mouse

Sebastian was featured as a recurring guest in House of Mouse. He is usually seen with Ariel.

In the beginning of the episode "Big Bad Wolf Daddy", Sebastian was served alive as Ariel's dinner. This was the only time in the series where Sebastian was treated this way, unlike Flounder, whom was frequently treated this way in the series.

One of his most notable appearances is in the episode "The Mouse Who Came to Dinner" where Mortimer Mouse acts as if he's the critic (when the real critic was Lumiere) and demands Goofy to make him shellfish for dinner. Goofy claims they're all out and uses Sebastian as a substitute. Sebastian and Goofy end up in a comical chase for the rest of the episode until Mortimer's charade was exposed.

In "Max's Embarrassing Date" Sebastian begins to perform "Kiss the Girl" for Max and Roxanne, but is stopped when Max loses his temper, because he didn't want all of this attention. He only wanted privacy.

In the beginning of the episode "House of Magic" Mickey Mouse told a joke about him having trouble coming into the club, humiliating the crab.


He also made a brief appearance in Aladdin. When the Genie, whilst trying to find the right recipe for turning Aladdin into a prince, is looking at the Royal Recipes book, he pulls out Sebastian (clamped to his finger) and flicks him off. For a few seconds during his appearance, "Under the Sea" can be heard.

Sebastian briefly appeared in the movie version of "Dalmatian Vacation", the series finale to 101 Dalmatians: The Series, in which he pinches a puppy's tail. However, the song sequence containing this cameo was often cut from televised broadcasts of the episode.

Sebastian makes a cameo in the Darkwing Duck comic book. He can be seen on the last page of issue #7, hiding from the revived Paddywhack.

Sebastian and Flounder currently star in commercial bumpers for the Disney Junior Channel and the Disney Junior block on the Disney Channel. These short showcase Sebastian and Flounder engaging in activities, accompanied by a song from an off-screen singer.

Kingdom Hearts

Sebastian appears in the popular video game series alongside other major characters from the film in the world of Atlantica. Here, the crab is voiced by Kevin Michael Richardson.

In the original Kingdom Hearts, Sebastian is tasked with keeping Ariel under tight supervision, as King Triton believes her fascination with the worlds outside Atlantica have gotten out of hand. After Ursula uses this dream to seize control over the ocean, Sebastian accompanies Ariel with Sora, Donald and Goofy on their mission to defeat Ursula, restoring peace once her death comes into fruition.

Sebastian would appear in the official sequel, Kingdom Hearts II, where Ariel becomes infatuated with the human world, prompting the king to have Sebastian join Ariel in his orchestra for an upcoming concert. Sebastian does so, but getting Ariel's mind off the surface proves to be difficult, resulting in the king finding out Sebastian's efforts to follow orders have failed, much to the crab's dismay. Like in the film, Ariel goes to Ursula for assistance, leading into her human transformation, her romance with Eric, and finally having her father realise the human world isn't as bad as it seems.

Sebastian also plays a minor role in Kingdom Hearts: Chain of Memories.
