Freaky toy idea

A toy that's shaped kind of like a rake (but very small) and without the handle. You wind it up and as it unwinds, a helix or other shape inside that's connected to all the inner prong ends that spins causes the outer ends to move in a pattern that makes the toy 'crawl' forward... very quickly. No wheels, just rake-like prongs in front and a smooth curve on back to slide on the floor.
