The Hot Wheels Monster Trucks Color Reveal trucks pack awesome surprises! Inside each barrel drum is one 1:64 scale Hot Wheels Color Shifters Monster Truck that's covered in special Color Reveal coating and a clip-on water tank. For the initial reveal, fill the drum with water and swirl the truck around in it until the water changes color, then pull it out to reveal the Monster Truck and its deco! Want to change its appearance again? Fill the drum with icy cold water and dunk it in to watch the colors magically change! Change it back by dunking it in warm water! Use the clip-on water tank to spray oncoming Color Shifters trucks with deco-changing water for an epic water battle. Kids will want the entire collection. Each sold separately, subject to availability. Colors and decorations may vary. Inside the Hot Wheels Monster Trucks Color Reveal barrel drum is an awesome Monster Truck with a surprise deco just waiting to be discovered. Which truck is hiding inside? Use the reusable barrel packaging as a dunk tank, fill it with water, and swirl the truck in it. Watch as the water changes color and a new deco is revealed! More color-changing surprises await when kids dunk their truck into icy cold water to magically reveal yet another deco and design instantly change it back with warm water. Repeat this over and over again to change between the 2 looks! Use the clip-on water tank to spray other Hot Wheels Monster Trucks Color Shifters with temperature-appropriate water to change-up their decos, adding a sweet bonus water battle to the crashing and smashing fun!
