About Sebastian
He is a red Jamaican crab and was announced as being the "royal court composer", and conducts a concert that King Triton's seven daughters are supposed to perform. 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. Feeling guilty for having "betrayed" Ariel, Sebastian 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. Sebastian was born in Jamaica and went to Music Academy in Trinidad prior to joining King Triton's staff as his assistant. According to Disney's Sebastian 1, Arthur Fiddler Crab was his teacher.
