Mrs. Johnson is Oobi's elderly neighbor and one of Grampu's closest friends. She is one of the few left-handed puppets on the show. Her first name is unknown. It is implied that she is or was once married, though she is never shown with a husband. Her house is known for having the most spectacular Halloween display in Oobi's neighborhood every year, since she routinely decorates her doorway with all kinds of interesting ornaments.
