List of characters

Grandma SquarePants is the paternal grandmother of SpongeBob SquarePants and the mother of Harold, Sherm, and Blue. Her first appearance is in the episode "Grandma's Kisses."


She is a dark orange sponge and wears a light green and pink dress and light blue glasses, and has light purple hair and pink lips. She enjoys making gingerbread men, chocolate chip cookies, and homemade sweaters with metaphorical love in every stitch. She also is very affectionate and likes to give a lot of kisses (shown in "Grandma's Kisses.")


She is shown to be a very kind and sweet grandmother to SpongeBob. She once treated SpongeBob like a baby ("Grandma's Kisses") but later learns that he wanted to be treated like an adult.


She may have been born to SpongeBob's Great Grandmother.

When she was an adult, she married the sponge who is now known as Grandpa SquarePants.

They had Harold, Sherm, Blue, and one other son and one daughter, one other son and two daughters, two other sons and one daughter, or three other sons.

She now lives alone in her home. Once in while, she is visited by her family members, usually SpongeBob.

At some point, she met Patrick Star, most likely when SpongeBob and Patrick were children.

She has also been to the Krusty Krab, SpongeBob's job, at least once.[1]

She is so old that she can't even remember how old she is.

At some point in her life, she gained a driver's license and a car.

At some point, she either invented or obtained a family recipe for Snickerdoodles.[2]


  • She acts like a mother to just about everyone she knows.
  • In the game, Employee of the Month, she constantly mistakes SpongeBob for Patrick, even when SpongeBob corrects her.
