Place this 3" tall robot character on a smooth, flat, horizontal surface (window, file cabinet, wall, door, computer monitor, etc.), press firmly so it sticks and watch him crawl his way down! His articulated arms and legs will be moving the whole way. Good old fashion gravity does all the work, no batteries required. Comes with the cute stock face shown and your imprint on the chest. CPSIA compliant. Great giveaway at trade shows and fairs, use him as a gravity lesson in science class and then give out to the students, sell in a school or museum bookstore or souvenir shop, terrific as a party favor and much more.
