Captain Blue SquarePants is a retired police captain and is one of the sons of Grandma and Grandpa SquarePants, he is the uncle of Stanley, BlackJack, SpongeBob, and Todd, and brother of Sherm and Harold. His only appearance is in the episode "BlackJack." During the episode, SpongeBob said he needed some help from a crime fighter like Blue to save his parents from Blackjack, but Captain Blue told SpongeBob that he was retired from being a police captain.


Captain Blue is shaped like a sea sponge while SpongeBob is shaped like a kitchen Sponge. Blue has holes all over his body and is light orange in color. Blue has a few yellow teeth left, wears a blue cap, and has a gray beard, and wears brown pants. He may have somewhat impaired hearing or just couldn’t hear what SpongeBob was saying over the loud things he was doing.


Captain Blue is very lazy, but it is probably because he is retired. He enjoys drinking Clam Tomato Chowder Juice, listening to country music on his old record player, and talking on a CB radio.


He was born to Grandma and Grandpa SquarePants.

When he was an adult, he became a police captain for the Bikini Bottom Police Department.

He later retired from this job.

He has no known/confirmed wife or children.

He lives next door to his nephew, BlackJack SquarePants.

At some point in his life, he gained a driver's license and a car.
