The title character is a sea sponge named SpongeBob. He has two neighbors: a pink starfish named Patrick and an arrogant octopus named Squidward. He works for a miserly crab named Mr. Krabs, who lives in an anchor with his whale daughter Pearl. SpongeBob attends a boat-driving school where he is taught by a pufferfish named Mrs. Puff. He often visits Sandy, a squirrel from Texas who lives in an air-filled dome. The villains of the show are a copepod named Plankton and his waterproof computer wife, Karen, who want to run Mr. Krabs out of business. SpongeBob also has a pet snail, Gary, who meows and acts like a cat.
