The character-driven cartoon chronicles the nautical and often nonsensical adventures of SpongeBob, an incurably optimistic and earnest sea sponge, and his underwater friends. Dwelling a few fathoms beneath the tropical isle of Bikini Atoll in the sub-surface city of Bikini Bottom, SpongeBob lives in a two-story pineapple. Instead of taking the logical approach to everyday challenges, SpongeBob approaches life in a wayward and unconventional way. Whether searching for the ultimate spatula to perfect his burger flipping technique at the Krusty Krab or just hanging out with his best friend Patrick (an amiable starfish), SpongeBob's good intentions and overzealous approach to life usually create chaos in his underwater world.

The series stars Gary Coleman and Todd Bridges as Arnold and Willis Jackson, two African American boys from Harlem who are taken in by a rich white Park Avenue businessman named Phillip Drummond and his daughter Kimberly, for whom their deceased mother previously worked. During the first season and first half of the second season, Charlotte Rae also starred as the Drummonds' housekeeper, Mrs. Garrett.

SpongeBob and friends spend the summer catching jellyfish, building camp-fires, and swimming in Lake Yuckymuck at Camp Coral, located in the Kelp Forest.
