Grandma Tucker is Craig's grandmother who has had only one appearance so far, which was in "Pandemic 2: The Startling", and even then it was just in a still picture and with no dialogue. She gave Craig a check for a hundred dollars. It is unknown if she is Mrs. Tucker's mother or Mr. Tucker's mother.
Grandma Tucker has long gray hair as well as various facial wrinkles. She wears a light purple sweater, white shirt, and light brown pants.
- Technically speaking, it is because of her that Craig was asked to join the Peruvian flute band with Eric, Stan, Kyle, and Kenny, since it was her that gave Craig $100, so it was basically thanks to her that the ancient prophecy was fulfilled.
