A yellow anthropomorphic sea sponge who physically resembles an artificial, rectangular, kitchen-type cleaning sponge clad in brown short-pants, a white shirt, and a red tie. He lives in a pineapple house and is employed as a fry cook at a fast food restaurant called the Krusty Krab. SpongeBob's hobbies include practicing karate with Sandy, as well as jellyfishing, blowing bubbles, playing games with his best friend, a starfish named Patrick Star, and unintentionally irritating his other neighbor, Squidward Tentacles. He attends Mrs. Puff's Boating School but has never passed.
