The Hot Wheels Monster Trucks Arena Smashers Color Shifters 5-Alarm Rescue toy offers impressive action with color changes. The set includes the Color Shifters HW 5-Alarm car, which can be driven into an ice tank to trigger the first color change. Then, the goal is to hit a flame wall behind a stand. When the car collides in the right position, the 5-Alarm crashes into the stand, while the two included cars end up in hot water, causing another color change in the 5-Alarm. The rotating mechanism allows excess water to be removed before repeating the challenge.
