Goofy is going to spend the holidays in his mountain shack, when he happens upon a most unusual sight: an old witch hanging miserably from a tree branch. The hag soon explains that she fell from her broom and, in her current state, is unable to perform any magic to free herself. Goofy, naively trusting as always, decides to help « thuh poor lady ». Free and magical once more, Grimhilde, in a rare show of kindness, decides to thank her unexpected savior by granting him a wish. Goofy decides that he does wish his shack were bigger on the inside… The wish is granted, but things don't go as planned.
