The Supreme Machine Rocket Bots put the meta in metamorphosis. They go from car to robot based on their position! With all 4 wheels planted on the ground, they naturally take to the form of a car, and when they are set back onto their trunk/feet, they turn into a robot (the secret ingredient is gravity). This T-Rex Attack Launch Track propels the Rocket Bot thru the mouth of a robot T-Rex with the push of a button. The spring-loaded launcher is easy to pull back, but strong enough to send the Rocket Bot from zero to fun real quick. The track is simple to assemble, and it includes an array of signs for the journey. The end of the track slopes upwards for mad air. No batteries required!
