In The Super Mario Bros. Movie, the grandfather is shown living with Mario and Luigi's mother, requiring her help to feed him. He wears an old-fashioned green hat and a plaid reddish-brown and green shirt. He appears with Uncle Arthur and Uncle Tony during dinner, laughing at Mario and Luigi about their Super Mario Bros. Plumbing commercial, though he has no interest in the conversation. Being old and toothless, he uses crutches to walk and needs to be helped when eating.
