With the Hot Wheels Monster Trucks Color Change 1:64, exciting crash action can be reenacted, and each truck can take on two colors. By dipping it in ice-cold water, the original appearance of the color-changing truck magically transforms, and warm water reverses the effect. Kids can repeat the process as often as they like to switch between colors. The wide selection of cool color-changing Monster Trucks promises plenty of fun for collectors. All items are sold separately. Colors and designs may vary.
