SpongeBob SquarePants 

SpongeBob is a childish and joyful sea sponge who lives in a pineapple with his pet snail Gary in the underwater city of Bikini Bottom. He works as a fry cook at the Krusty Krab, a job which he is exceptionally skilled at and enjoys thoroughly. He attends Mrs. Puff's Boating School, and his greatest dream in life is to receive his boating license. Unfortunately, he tenses up whenever he has to drive a boatmobile, and he drives recklessly. SpongeBob is very good-natured and loves to hang out with his best friend Patrick. His teacher is Mrs. Puff and his boss is Mr. Krabs.

Patrick Star 

Patrick is SpongeBob's best friend as well as one of his two neighbors. He is a naive and overweight pink sea star. He lives under a rock in the underwater city of Bikini Bottom. SpongeBob and Squidward are his two neighbors, and, when viewed on the front side, are to the right of his residence. He and SpongeBob both like to bother Squidward; though they do it unknowingly and have good intentions. He is the son of Herb Cecil and Margie Bunny Star and the brother of Sam Star and adoptive brother of Squidina Star.

Squidward J. Q. Tentacles 

Squidward is SpongeBob's very grumpy neighbor and coworker who lives in an Easter Island head. He is an arrogant artist and musician, and his favorite hobbies are painting self-portraits and playing the clarinet. Even though Squidward's name contains the word squid, he is an octopus and not a squid. He is a very cynical, selfish and a stick-in-the-mud individual. He works as the cashier at the Krusty Krab, a job he hates. Squidward is frequently annoyed by SpongeBob's loud and cheerful behavior, but he sometimes sticks up for SpongeBob and sees him as a friend on occasion.

Eugene Harold Krabs

Mr. Krabs is a red crab who lives in an anchor with his daughter, Pearl, who is a young whale. He is the owner and founder of the Krusty Krab restaurant as well as the employer of both SpongeBob and Squidward. Mr. Krabs' most prominent trait is his greediness and obsession with money, meaning he's also obsessed with wealth, to the point where he occasionally treats money and wealth better than his daughter and employees. Mr. Krabs' only business competition comes from the Chum Bucket, a failing restaurant run by Sheldon Plankton and his wife Karen. Plankton and Karen are constantly scheming to steal the Krabby Patty secret formula that makes the Krusty Krab so successful.

Sandra Jennifer Olivia Sandy Cheeks 

Sandy is an American squirrel from the surface who wears a diving suit and lives in an air-filled glass treedome to survive underwater. She is a thrill seeker who loves extreme sports and karate. Having come from the state of Texas, she has a Southern drawl and a love for rodeos. She works as a scientist and built both her treedome and air suit herself. She is also a member of the Gal Pals along with Karen, Mrs. Puff, and Pearl.

Mrs. Poppy Puff 

Mrs. Puff is SpongeBob's teacher at Boating School, where she teaches students how to drive boats like underwater cars. She is a pufferfish who wears a sailor uniform. Teaching and driving are her passions in life. She is talented at both, having successfully taught every student other than SpongeBob how to drive. She and SpongeBob are always on an endless quest to get him a driver's license, but due to his reckless boating skills, they never succeed. Her boating school is the only one in the ocean and is very popular. Mrs. Puff's school is attached to a submerged lighthouse and surrounded by a stunt-driving course.

Sheldon J. Plankton 

Plankton is a planktonic copepod who runs the Chum Bucket restaurant alongside Karen, a waterproof computer who is his sidekick and wife. The Chum Bucket is highly unpopular in Bikini Bottom because it serves chum, a type of bait made from fish meat. Plankton despises his rival, Mr. Krabs, for running a successful restaurant because his own business rarely gets any customers. His main goal is to steal Krabs' secret formula for Krabby Patties and running Mr. Krabs out of business. Karen gives him a variety of plans to steal it, but their efforts always end up failing in the process.

Karen Plankton 

Karen is a waterproof supercomputer who lives in the Chum Bucket laboratory. She is Plankton's wife and sidekick who supplies him with evil plans to steal the Krabby Patty formula. As a computer, Karen is the smartest resident of Bikini Bottom and has a clever, analytical personality. She has two main forms: a big monitor on the wall or a portable wheeled computer. Along with her role as co-owner of the Chum Bucket, she works as the chef and cashier. She rarely has to fulfill these jobs due to the restaurant's unpopularity.

Pearl Krabs 

Pearl is a teen whale who lives in a hollow anchor with her father Mr. Krabs. When Pearl grows up, Mr. Krabs wants her to continue the family business by inheriting the Krusty Krab and becoming its owner.

Garold Gary Wilson Jr. 

Garry is a domesticated house pet with similar mannerisms to the real-world cat, most notably his meow sound, as snails are the underwater equivalent to cats in the show, he also has the abilities of dogs from fetching to doing tricks. It has been suggested that SpongeBob has had Gary ever since he was a young boy.
