Characters Present

Featured

SpongeBob SquarePants - An incredibly optimistic square sponge who lives in a pineapple under the sea, he is the lead character of the show. He works at the Krusty Krab with his neighbor Squidward.

His interests are bubble blowing, jellyfishing, playing super heroes, and "doing things" with Patrick. He is very pliable and rubbery, and is capable of stretching, inflating, multiplying, or even breaking apart. He is a terrible driver and goes crazy behind the wheel of a boat (the car of Bikini Bottom). Voiced by Tom Kenny.
Squidward Tentacles - A misanthropic octopus (Stephen Hillenburg insists Squidward is an octopus and not a squid) that lives in an Easter Island moai between the domiciles of SpongeBob and Patrick. Although loved by the other characters, Squidward is pessimistic, antisocial, and curmudgeonly. He is an artist who paints and plays the clarinet horribly. Voiced by Rodger Bumpass.
