The Fast-Slow Stegosaurus Toy

This little wind up toy Stegosaurus has one unusual feature about it. Normally you wind these toys up and set them going, and they shoot of across the table, and that is it.

This one has an extra feature. As you set it going, it first trots along quite slowly, and then it suddenly switches to high speed motion, then it slows down again. I adds a bit of unpredictability to the motion, and somehow makes the toy ever so slightly more life like!
