Great idea for a little girl! Minnie Mouse Mobile (Minnie Bow-bile) transformed a Cozy Coupe! The ears were cut from 3/4" scrap rubber. They were screwed into the car on the underside of the roof. The bow is constructed from a piece of plexi glass that was painted. This was attached to the ears with a high adhesion waterproof glue.
Great idea. Mr. Freeze has frozen Batman and Robin...the kids will save them by squirting them with water guns! (Great birthday party game, whether it's a summer or winter party. Princesses, superheroes...pretty much anything.)
