This is a movie about a mechanic whose car breaks down. He makes friends with this Aunt and her niece, who turns out to be a boy, while he works on his car. I remember the Aunt tying the boy up to a piano and pounding on it very loudly. The boy also tries to hide a frog in his closet but gets caught and the aunt takes an egg and tells the boy that this will be his frog if he tries it again and she squishes the egg between her fingers.
