Knuckle Headz combine the fun of a fast and furious pull back race car with the crazy action of a demolition derby for all out racing mayhem! Knuckle Headz feature a crazy driver who is ready to lose their head to win the race! Pull the car back along any hard, flat surface and let go to see your car fly across the room. Then get ready for the Poppin' Action - a square hit to the front of the car and the driver's head will fly into the sky! See how straight you can point the car so it will hit its target or point one car right at the other to see who will lose their head!
