SpongeBob's Core Friend Group
SpongeBob SquarePants' closest friend is Patrick Star, a pink starfish who lives under a rock next door to SpongeBob's pineapple house at 124 Conch Street in the fictional underwater city of Bikini Bottom. Patrick is described as SpongeBob's best friend and neighbor, and their dynamic is central to the show's humor and storylines. The series, created by marine science educator and animator Stephen Hillenburg, first premiered on Nickelodeon in 1999 and has since become one of the longest-running animated series on television. You can find the official show overview on the Nickelodeon website here.
The main cast of the show includes Tom Kenny as SpongeBob and Bill Fagerbakke as Patrick, with the series often listing the core friend group as SpongeBob, Patrick, Squidward Tentacles, Sandy Cheeks, and Mr. Krabs. Sandy is a squirrel from Texas who lives in an underwater dome and is a scientist and karate expert, while Squidward Tentacles is SpongeBob's grumpy neighbor and co-worker at the Krusty Krab. Mr. Krabs is the owner of the Krusty Krab restaurant where SpongeBob works as a fry cook. The show's official character guide on the Nickelodeon site provides the full list here.
