SpongeBob SquarePants is the main character in the American anime SpongeBob SquarePants. He lives in a city called Bikini Bottom at the bottom of the Pacific Ocean and is a yellow rectangular sponge whose body is made up like a cleaning sponge. His arms, legs and lower body limbs can grow again without restriction after being broken, and when torn into pieces he can reproduce many miniature doppelgangers, and has holes in his body that can shoot high-pressure water guns, and can use his body to trap huge objects inside him.
