Living two houses away from SpongeBob is his best friend Patrick Star, a dim-witted yet friendly pink starfish who resides under a rock. Despite his mental setbacks, Patrick sees himself as intelligent. Squidward Tentacles, SpongeBob's next-door neighbor and co-worker at the Krusty Krab, is an arrogant, ill-tempered octopus who lives in an Easter Island moai. He enjoys playing the clarinet and painting self-portraits but hates his job as a cashier. He dislikes living between SpongeBob and Patrick because of their childish nature. The owner of the Krusty Krab is a miserly red crab named Mr. Krabs who talks like a sailor and runs his restaurant as if it was a pirate ship. He is a single parent with one teenage daughter, a sperm whale named Pearl, to whom he wants to bequeath his riches. Pearl does not want to continue the family business and would rather spend her time listening to pop music or working at the local shopping mall. Another of SpongeBob's friends is Sandy Cheeks, a thrill-seeking and athletic squirrel from Texas, who wears an air-filled diving suit to breathe underwater. She lives in an oak tree entrapped in a clear glass dome locked by an airtight, hand-turned seal and is an expert in karate, as well as a scientist.
