Horatio Thelonious Ignacious Crustaceous Sebastian is a red Jamaican crab and major character in Disney's 1989 animated film The Little Mermaid. He is the "distinguished" court composer for King Triton, and is regularly tasked with watching over his youngest daughter, Princess Ariel.

He is voiced by Samuel E. Wright.


The Little Mermaid: Ariel's Beginning

Sebastian is the heir of King Triton. He and King Triton keep an eye out to ban any musician from Atlantica. Though he agrees with King Triton, Sebastian usually is seen playing music in the Catfish Club Band. He and the band members are arrested by the king's guards in jail. Being arrested, he and the band members start a prison riot and escape to bring music back to Atlantica. He and Ariel's friends stand up against Marina Del Rey and the music of Athena's song has brought her back to life. Sebastian later listens to King Triton's misunderstanding and becomes the royal court composer.

The Little Mermaid

After the prequel, Sebastian is presented along with his assistant King Triton. He is forced to keep a watch on Ariel. Sebastian has heard about Ariel falling in love with Prince Eric. Later, he convinces Ariel that the human world is too dangerous for her, so it is better to go under the sea. After King Triton destroys Ariel's treasures, Sebastian plays another signature song about Eric and Ariel falling in love as humans. He dislikes marine animals which are cooked, so he avoids Chef Louis. During the wedding, Sebastian and the other animals disrupt the wedding of Vanessa and Eric. Sebastian is later seen during the wedding of Prince Eric and Ariel.

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 (much to Sebastian's chagrin). Sebastian disapproves of Melody's obsession over the sea, knowing the dangers that lie within them (namely the witch Morgana, who seeks to unleash her wrath upon Melody and her family), but the headstrong princess fails to listen, finding herself completely captivited by the world of the ocean.

One evening, during a ball, Sebastian accidentally finds himself in the ballroom, amongst the crowd of royals, and more importantly, the psychotic Chef Louis, who tries to murder the crab out of spite. Sebastian manages to escape, but unintentionally embarrasses Melody in the process, reinforcing her fear of being an outcast amongst her fellow royals. Later that night, Sebastian tries to cheer up the child, but it results in her leaving into the sea. Sebastian quickly informs Ariel and Eric, and a search breaks through. King Triton is informed of this and, after turning Ariel back into a mermaid, the team takes the search into the waters. Eventually, the family finds themselves battling Morgana at the sea witch's lair. She soon meets her defeat at the hands of Melody, and with her out of the way, peace can be restored between land and sea.
