SpongeBob is a sea sponge, but he resembles a kitchen sponge. He has large blue eyes, many holes appearing all around his body and a mouth with prominent front buck teeth. He typically wears a white shirt with a red tie and brown square trousers, hence his family name "SquarePants".
SpongeBob is a fry cook at the Krusty Krab restaurant, at which he has won employee of the month many times (374 as mentioned in The SpongeBob SquarePants Movie). He attends Mrs. Puff's Boating School, analogous to a driving school, but cannot pass the boating test until "Gone". SpongeBob lives with his pet snail Gary in a large "pineapple-house" on 124 Conch Street in fictional Bikini Bottom, which is located beneath the real tropical isle of Bikini Atoll. His neighbors are Squidward, who is a squid and SpongeBob's co-worker at the Krusty Krab, and Patrick, a starfish who is SpongeBob's best friend.
SpongeBob is an optimistic and energetic character, but also very naive. His hobbies include jelly-fishing (similar to bird watching and butterfly catching) and blowing bubbles with Patrick. He is unaware of how Squidward is annoyed by him.
Appearance in UltimaEditSpongebob plays a major role in the Ultima universe. It was first discovered that Spongebob was apparently the leader of the Society. How he became leader is currently unknown, though it is said to be revealed in the upcomming story, Ultima: The Origin of the Society, which is a part of the Universal Takeover Saga.
In Ultima: the Crossing of Universes, Spongebob makes his first appearence as the other cartoon characters introduce Nick to him (much to Spongebobs glee). Throughout The Crossing of Universes, Spongebob has accompanied Nick on his many adventures and has become the official wielder of the Ultimastaff. By the end of the third story arc, Spongebob relinquishes his leadership role and passes it down to Nick.
