SpongeBob SquarePants is the protagonist of the series. SpongeBob is a rather childish sponge who enjoys blowing bubbles and catching jellyfish. His best friend is the lovable Patrick Star.
He works as a fry cook at the Krusty Krab, where he is known for preparing the most delicious Krabby Patties under the sea. He is the most attentive and obsessive student at Mrs. Puff's Boating School, but his nerves always get the best of him when he tries to drive a boat. He fails every driving test he takes! SpongeBob lives in a pineapple with his pet snail Gary. His next-door neighbor is a grumpy octopus named Squidward Tentacles.
SpongeBob's favorite hobby is blowing bubbles. He uses a special technique to blow bubbles in different shapes. He also loves jellyfishing, a popular sport in Bikini Bottom that involves catching jellyfish with nets and then letting them go. He also loves to make friends with everyone he meets. Aside from Patrick, he is good friends with Sandy and Pearl. He has even tried to befriend the evil villains Plankton and Karen, but they hate him.
