SpongeBob SquarePants (born July 14, 1986) is the main protagonist and eponymous character of the Nickelodeon animated comedy series of the same name. He was designed by former marine biologist and animator Stephen Hillenburg, and is voiced by Tom Kenny. He first appears in the series' pilot episode "Help Wanted."
SpongeBob is a childish, joyful, eccentric sea sponge who lives in a pineapple on 124 Conch Street with his pet snail Gary and pet scallop Shelley in the underwater city of Bikini Bottom. He works as a fry cook at the Krusty Krab, a job in which he is exceptionally skilled. He attends Mrs. Puff's Boating School, though has yet to receive a driver's license due to his inability to drive a boatmobile. SpongeBob lacks a lot of knowledge and is a constant annoyance to those around him, but he is very good-natured.
He appears in all of the episodes in the series, except for "The Algae's Always Greener," in which his alternate-universe counterpart appears instead. He was soon to be Nickelodeon's main mascot.
