Track Builder is all about experimenting and developing skills that drive problem solving and crank up the competition! This awesome transforming set with three challenges and an epic payoff provides continuous play with no set up or assembly in between the skill-based challenges. Complete the 3 stunts to launch the rocket. First, hit the slam launcher to fly the car through the loop, then hit the rocket to ignite one of the engines that will pop out to let kids know they did it right! The loop collapses automatically into a ramp. Launch a car to jump the monster gap, hitting the rocket to ignite the second engine and release the ramp that preps the rocket for launch! Final countdown- race up the ramp and blast off the cap of the rocket! Challenge Accepted™! Includes one Hot Wheels© vehicle.
