  • Unlike many other recurring characters, a lot of her personal life is unknown. She was born in the late 1980s, and her grandmother once told her about the old subway systems that existed across the world before Monotrains were invented. (The Complete Book of Thunderbirds, Vault Of Death)
  • It's rumoured Grandma's first name is Cecilia.
  • The Grandma puppet was provided with a "normal", "smiler", "frowner" and "blinker" head.
