Beloved characters in Spongebob Squarepants. ;)

SpongeBob SquarePants  is an extremely energetic and optimistic sea sponge (although his appearance more closely resembles a kitchen sponge) who lives in a pineapple under the sea with his pet snail 

Gary, who meows like a cat. Although Gary only actually speaks in a few episodes, (mainly in "Sleepy Time" in Spongebob's dream world, where Gary is portrayed as a librarian with an English accent) the characters have shown an ability to understand him. Living two houses down from SpongeBob is his best friend

 Patrick Star, a dim-witted yet friendly pink seastar who lives under a rock. Living between the two is 

Squidward Tentacles, an arrogant and egotistical squid (although, often, people believe he is an octopus, yet, "squid" is in his name...) who lives in an Easter Island moai and dislikes his neighbors (especially SpongeBob) for their child-like behavior. He enjoys playing the clarinet and painting self-portraits.

Another close friend of SpongeBob's is 

Sandy Cheeks, a squirrel from Texas. Sandy is an expert atkarate and lives in an underwater tree dome. When not inside her tree dome, she wears an astronaut-like suit because she cannot breathe in water. SpongeBob and Squidward's employer is former officer cadet for the Bikini Bottom Navy force and war veteran 

Eugene Krabs, a miserly crab obsessed with money, who is the owner of the Krusty Krab restaurant. Mr. Krabs has a whale daughter, named 

Pearl. who is a teenage cheerleader. The reason why Mr. Krabs' daughter is a whale is unknown. Mr. Krabs’ archenemy is 

Sheldon Plankton, a small green copepod who owns a low-rank fast-food restaurant called the Chum Bucket across the street from the Krusty Krab. Plankton spends most of his time planning to steal the recipe for Mr. Krabs's popular Krabby Patty burgers to obtain success, though his schemes always end in failure.
