This is the 500-piece LEGO® set that sparks a child’s creativity and engineering skills with seven gear-driven mini builds that whirl, flap, dance, and more. Easy pictorial instructions make it easy for even first-time builders to construct a rotating windmill, a hand crank pipe organ, a pond with swimming fish, and a pirouetting ballerina to a push-along helicopter with spinning rotors, a bird who flaps his wings while perched on a tree branch, and an apple with a pop-up worm. As kids gain confidence and experience, they can snap together the bricks and gears into kinetic creations of their own design. Ages 5 and up.
