One of the reasons SpongeBob SquarePants has been successful is because the show's characters are so eccentric and endearing. Here's a list of the main characters from SpongeBob SquarePants.
SpongeBob SquarePants
Nickelodeon
SpongeBob SquarePants is optimistic and upbeat all the time. He lives in a pineapple next to Squidward and Patrick. SpongeBob works as a fry cook at the Krusty Krab. He wakes every morning to the sound of a fog horn alarm clock. His favorite pasttime is jellyfishing.
Patrick Star
Nickelodeon
Patrick may not be the brightest starfish in the sea, but he's still SpongeBob's best friend. Patrick lives under a rock next to Squidward and SpongeBob. He's pink, he likes to eat and he likes to go jellyfishing with SpongeBob. Not too many people know, he can play his belly like a drum.
Squidward Tentacles
Nickelodeon
Squidward is SpongeBob's cynical and sarcastic neighbor. He plays the clarinet and boasts to be an exceptional artist, which you can see when you enter his house, covered in self-portraits. Squidward works the cash register at the Krusty Krab. Once, he moved away but found he missed the spontaneity of living next to SpongeBob (though he'd never say it out loud).
Mr. Krabs
Nickelodeon
Mr. Krabs owns and operates the Krusty Krab restaurant, home of the Krabby Patty. He's a sailor who worships money. His daughter Pearl, a whale, lives with him in their anchor-shaped home. He's notoriously cheap and frequently cracks the whip on SpongeBob and Squidward, once even keeping his restaurant open 24 hours, every day, in order to compete with his arch nemesis, Plankton.
Plankton
Nickelodeon
Plankton is an evil, tiny enemy who owns a failing restaurant called the Chum Bucket. He tirelessly tries to steal the recipe for Krabby Patties. He seeks to rule all of Bikini Bottom. His schemes have included disguising himself as Mr. Krabs, befriending SpongeBob and switching lives with Mr. Krabs.
Gary
Nickelodeon
Gary is SpongeBob's pet snail, who meows like a cat. He sleeps on newspaper next to SpongeBob's bed. It's been shown more than once that Gary is an intellectual, knowing how to tie his shoes and dreaming about browsing a library. Once, Gary ran away when SpongeBob forgot to feed him for days. But he returned when he realized he was in danger and SpongeBob missed him.
Sandy Cheeks
Nickelodeon
Sandy is a squirrel from Texas. She is also a good friend of SpongeBob's. She lives in a bubble dome and wears an astronaut suit out into the water, so she can breathe. She is an expert at karate, an inventor and hibernates on schedule. Plus, she taught SpongeBob all about Christmas
Flying Dutchman
Nickelodeon
The Flying Dutchman is a ghost feared by Bikini Bottom residents. He's had run-ins with SpongeBob, Patrick and Mr. Krabs, sometimes involving his ghost ship and some socks.
