Mary's Mother is an old, weak and dried up woman. She appears in Chocolate With Nuts when SpongeBob and Patrick sell chocolate to her. She and Mary also go on a date with SpongeBob and Patrick at the end of the episode. She can barely hear and can get very angry when she cannot hear anything. She is at least old enough to remember when chocolate was invented. Mary's Mother has a possibility to be dead by now. She never made another appearance after the episode Chocolate With Nuts.
A brownish color. Very old and dried up. No legs or arms, just a spine and head. Her head is kind of a resemblance to a skull.
- She was voiced by Tom Kenny.
