Mrs. SquarePants (nee Bubblebottom) (born October 23, 1959) (age 51) is Harold's wife, SpongeBob's mother, daughter-in-law of Grandpa and Grandma SquarePants, sister-in-law of Captain Blue and Sherm, and the aunt of Larry, Todd, Blackjack, and Stanley. She gave birth to Spongebob in 1986 when she was 27 years old.
She has black hair and is dressed in a purple matchbox dress with matching sleeveless pantalets and has a pearl foot.
She debuted in "Home Sweet Pineapple". After Nematoads ate SpongeBob's home, she and her husband came to pick him up. Patrick Star later tried to stop them from taking his friend away. When SpongeBob gets his house back, she and the others 9except Squidward) cheer for this.
Claire and her husband later appeared in "Culture Shock" to watch her son perform in the talent show.
In "No Free Rides" She gives SpongeBob a boatmobile as he "passed" his driving exam.
