Ben 10 Alien Creation Challenge
Set the time, build an alien; built it fast, or the aliens blast
Create your custom alien before time runs out. Pull a card, start the timer and create your alien before your time is up and all your aliens pop up. Set includes four translucent alien figures as well as eight combo cards for challenging game play. A special alien key unlocks the figures. To keep things tidy, the set also serves as a storage bin for the figures. You can download additional combo cards for more challenging play when you are ready.
