The Hot Wheels Action Spiral Speed Crash Track Set offers thrilling excitement with a 29-inch high track, three crash zones, and a motorized booster that keeps the car in motion. Drive the included Hot Wheels vehicle to the booster and watch it zoom down the spiral continuously. To increase the challenge, add more cars until an inevitable crash occurs in one of the crash zones. Up to six cars can be stored on top of the battery box and the booster. Additional cars are sold separately. Colors and decorations may vary.
