Snap the pieces together to start your creations... if you can imagine it, you can make it! Design your mansion however you want, and try other things, too! Arrange all of the fun accessories, along with the stickers, or add your own accessories and artwork! Then bring your creations to life with the circuits and motors -- the garage door opens and closes, the elevator goes up and down, and the pool rotates! Requires 4 AAA batteries, not included.
