While her face was hidden from the viewers, her red hair was shown and her voice was heard. She appears to be slender and rather tall, with light fair skin similar to Goofy's muzzle where the whiskers extend outward. Not much is known about her, except for the fact that she was nearly as goofy as her husband Goofy and known for her undesirable driving skills (it is possible that she died in a car crash).
According to the television series Goof Troop, she has since passed away, though the circumstances remain unknown. Goofy tells Max that "She's up there with the stars."
Both Glory-Bee and Penny Pooch are candidates for the mysterious Mrs. Geef. Glory-Bee due to her being around longer than Penny and has been known to have dated Goofy. And Penny due to her red hair and nose, which is how Mrs. Geef is described. Neither have been seen recently.
