Grandma SquarePants is the paternal grandmother of SpongeBob SquarePants and the mother of Harold, Sherm, and Blue. Her first appearance was in the episode "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 was born to two unknown parents.

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

Together, they may have bought the home that is now known as Grandma SquarePants' House, but this has not been confirmed.

They had at least 6 children: Harold, Sherm, Blue, and 3 unknown sons.

Sometime before 2000 [citation needed], her husband died, making her a widow.

After his death, she replaced their bed or removed his bed and replaced it with just one single-person bed.

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 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]
