He's absorbent and yellow and porous and lives in a pineapple under the sea! He gets up to lots of nautical nonsense! His best friend is a starfish named Patrick, he has a pet snail named Gary, his grumpy neighbor is Squidward the octopus, and he works for Mr. Krabs at the Krusty Krab (wherein I'm pretty sure there are a lot of nefarous things going into those krabby patties but we don't need to talk about that. Suffice it to say, his restaurant looks like a crab trap, and his daughter is a whale, not a crab, and I'm pretty sure he's one of the only -- if not the only -- crab in the entire show).
