These lean, green, speed machines are gassed up and ready to go! Build a LEGO Creator 31074 Rocket Rally Car with a powerful rocket engine, and activate boost mode to blast past every other car on the street. Next, rebuild into a powerful Jet Truck that really packs a punch! The turbo engine will propel you down city streets until it’s time for another rebuild. The Quad Bike is next, with big wheels for rocky terrain, and an impressive engine that ensures you’ll win any race you enter.
