The rotating motor has power that is transferred to the legs via crank plates to make the Turtle crawl. Each pair of legs (front and rear) are molded as one piece and front leg plate is attached with a ball joint that serves as a fulcrum to realistically imitate turtle crawling. Legs and body on which the gearbox is mounted employ transparent-colored parts, giving the turtle a funky look. Reverse switch is also transparent, giving you a peek at the turtle's internal mechanisms. Assembly is very simple with use of screws and snap-lock parts.
