Your child can build Monster Mutt, one of the most popular monster trucks in Monster Jam. The K'NEX Monster Jam Monster Mutt Building Set comes with over 30 parts, including a buildable body shell that works within the K'NEX system. There is also a working suspension, big, chunky, tires, and a K'NEXman driver. Authentic logos and graphics recreate the look of Monster Mutt. Once built, the truck represents a 1:43 scale. Your child can even use the box as a ramp. Step-by-step building instructions are also included with the K'NEX building set.
