- ―SpongeBob SquarePants
SpongeBob SquarePants (born July 14, 1986; age 31) 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 is 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 that he is exceptionally skilled. 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 (except the Season 3 episode "The Algae's Always Greener", where his alternate universe counterpart appeared instead), and he was soon to be Nickelodeon's main mascot.
SpongeBob has made a few appearances in both Cletus Comics and Sibling Rivalries, though these mostly consist of scenes with SpongeBob being seen on the TV. He has, however, made physical appearances in early comics of CC as gags, then disappeared from the series and was not mentioned again. He was shown on TV in the SR comics "Love is What Makes the World Go 'Round" and "Portrait of a Football Player". He also appeared in an easter egg cameo in "ApRiL fOoLs DaY: wIsCoNsIn StYlE!", where he and Patrick Star appear in their "surprised" form from The SpongeBob SquarePants Movie after hearing Claude Tena "talk" for the first time.
SpongeBob actually appears and is referenced more starting from Season 6 of Sibling Rivalries onward:
- Armando Vasquez paints a picture of the character in "Get Rec'd!"
- The siblings try to watch the show in "Attack of the BeastDroid" only to be met with a commercial break
- In "Wisconsin's Greatest Hero", Derrick compares his brain to SpongeBob stating that he is ready to absorb knowledge like a sponge
- Packie is seen to be watching the SB episode "Krab Borg" in the Season 7 comic "Brothers For Life"
- A kid appears wearing a SpongeBob Halloween costume in "Night of the Living Warriors"
