Strange giant rabbit creatures are after a schoolgirl. Well, actually, they’re only after her clothes. Avoid the bunny monsters and collect all the treasures to find the exit to the next stage. Every hit causes the girl to lose clothing until she is caught and the bunnies make off with her panties. There are some power-ups that freeze the bunnies, restore lost clothes, and make you invincible for a short time. The sound is ear-rape, though there is an option to turn it off.
