“The title character was introduced in the show’s theme song: ‘Absorbent and yellow and porous is he!’ Resembling an ordinary kitchen sponge wearing shorts and a necktie, SpongeBob had big eyes, two teeth and oversize pair of shoes. He lived in a pineapple under the sea at Bikini Bottom, with his pet snail, Gary, and was beamingly proud of his job making Krabbie Patties at the Krusty Krab eatery.”
