SpongeBob, a cheerful sea sponge, lives in a pineapple in the undersea town of Bikini Bottom and proudly flips burgers at the Krusty Krab. His best friend is Patrick, a dim starfish; his neighbour and co-worker Squidward, an octopus, can barely stand him; and his boss, Mr. Krabs, guards the secret burger recipe from a tiny rival, Plankton.
