In Disney/Pixar Cars, Mack is the happy, loyal big rig who never quits! This trailer is equipped to transport champion Lightning McQueen to his next race and transform his entire look! Mack’s massive trailer has an upper level to hold two water tanks, one for warm and one for cold water. To customize the Color Changers Lightning McQueen vehicle from black to red, simply dip him in the warm water! Then change him back to red by dunking him in the cold temp tank! Mack’s lower level is equipped to transport the champ and other Color Changers vehicles to their next big race. Just open up the back of the trailer and drive Lightning McQueen in, then close it up so and hit the road! Color change feature works with all Color Changers vehicles. Includes one Color Changers Lightning McQueen vehicle. Other vehicles sold separately, subject to availability. Colors and decorations may vary.
