SpongeBob SquarePants (born July 14, 1986) is the main protagonist and the eponymous character of the Nickelodeon animated comedy series of the same name. He was designed by marine biologist and animator Stephen Hillenburg, and is voiced by Tom Kenny. SpongeBob's a childish, joyful, 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 lacks a lot of knowledge and is a constant annoyance to those around him (especially Squidward Tentacles), but he is very good natured. He appears in all of the episodes in the series. He was soon Nickelodeon's main mascot.
