SpongeBob SquarePants is the main protagonist and the eponymous character of the Nickelodeon animated comedy of the same name. He was designed by marine biologist and animator Stephen Hillenburg, and is voiced by Tom Kenny. SpongeBob is a childish, eccentric sea sponge who lives in a Pineapple in the underwater city of Bikini Bottom. He works as a fry cook at the Krusty Krab, a job which he is exceptionally skilled at. SpongeBob is very immature and is a constant annoyance to those around him, but he is very good natured.
