Doctor Mac Wheelie wants to paint a dump truck. This is a very useful and necessary machine, which is designed for the transportation of heavy loads. Doctor Mac Wheelie will paint the body of the dump truck bright orange and the cab blue. The fuel tank with the exhaust pipe and the piston that lifts the dump truck body will be gray. Almost done! Once the job is completely finished, the dump truck will go to the construction site to unload sand to build the house.
