Le Pinch was one of the most complex wind-ups to bring to life. Moving like and inchworm across a flat surface, designing his two separate halves to relate to one another was no easy task. In time, we managed to sync up Le Pinch's movements and even get him to climb over small obstacles. Simply place your hand palm down on a flat surface and Le Pinch will inch his way over your fingers. This is a piece of wind-up toy mastery.
