The series revolves around SpongeBob SquarePants and his various friends. SpongeBob SquarePants is an energetic and optimistic sea sponge (although his appearance more closely resembles a kitchen sponge) who lives in a submerged pineapple and loves his job as a fry cook at the Krusty Krab.
He has a pet snail, Gary, who meows like a cat. Living two houses down from SpongeBob is his best friend Patrick Star, a dim-witted yet friendly pink starfish who lives under a rock. Despite his mental setbacks, Patrick still sees himself as intelligent.
Squidward Tentacles is SpongeBob's next-door neighbor and co-worker at the Krusty Krab. Squidward is an arrogant and ill-tempered octopus who lives in an Easter Island moai and dislikes his neighbors (especially SpongeBob) for their childlike behavior. He enjoys playing the clarinet and painting self-portraits, but hates his job as a cashier.
