Sebastian is a character in Disneys 1989 animated feature film The Little Mermaid. He is a red, Jamaican-accented crab who serves as King Tritons court composer and is one of the main protagonists in the movie. Sebastians full name is Horatio Thelonious Ignacious Crustaceous Sebastian. Although some of Sebastians features resemble a lobster, he is definitely a crab, as is stated in The Little Mermaid itself a few times.
