The series revolves around Spongebob and his aquatic friends. SpongeBob SquarePants is an energetic and optimistic yellow sea sponge who lives in a submerged pineapple. SpongeBob has a childlike enthusiasm for life, which carries over to his job as a fry cook at a fast food restaurant called the Krusty Krab. One of his life's greatest goals is to obtain a boat-driving license from Mrs. Puff's Boating School, but he never succeeds. His favorite pastimes include "jellyfishing", which involves catching jellyfish with a net in a manner similar to butterfly catching, and blowing soap bubbles into elaborate shapes. He has a pet sea snail with a pink shell and a blue body named Gary, who meows like a cat.
