Nice Mickey Mouse Kiki Ippatsu toy that's fun to have around at parties! This set comes with a Mickey Mouse figure, a barrel, and 24 plastic keys in four different colors (red, yellow, gray, and white - 6 keys per color). To begin playing, insert the Mickey Mouse figure into the hole at the top of the barrel, twist the barrel around while holding the Mickey Mouse figure (this is to randomize the correct hole), insert a key into any of the holes on the sides of the barrel until Mickey Mouse pops out of the barrel. The winner/loser (depending on what sort of games you're playing) is the one who pops Mickey Mouse out of the barrel first. No batteries required.
