The colour changing effect blows everyone away with this Hot Wheels Monster Trucks Arena Smashers Color Shifters 5 Alarm Rescue playset. Kids drive the included Color Shifters HW 5 Alarm into the removable semi-truck's tank of ice-cold water to trigger the first colour change before aiming for the wall of flames behind the bleachers. When they hit the crash point, 5 Alarm crashes into the grandstand: the two included destructible cars and the monster truck fall into the very warm water and already change colour again. A turn on the turntable ensures that excess water flies away. And off they go into the next round. Deviations in colour and design reserved.
