Chocolate, I remember when they first invented chocolate. Sweet, sweet chocolate. I always hated it!
— Mary's mother, "Chocolate with Nuts"

Mary's mother is an extremely old, hard-of-hearing fish who appears in the episodes "Chocolate with Nuts", "Ink Lemonade" and has her first major role in "Biddy Sitting." She lives with her elderly daughter, Mary.


She is ancient compared to just about anyone in Bikini Bottom. She even remembers the time when chocolate was invented. She is shriveled up to the point where she appears to be merely a head and a spine and thus must get around by a wheelchair. She has a severe hearing disability and no physical eyeballs left.


She is often bad-tempered and impatient, often irritating her daughter. Due to having a hearing disability, she has to have people repeat themselves for her a number of times and with a tone of voice as loud as possible. She despises chocolate, though develops an interest in it after being falsely told that rubbing it on oneself causes the user to live forever; from this instance, it is revealed that she wants to be immortal.
