I'm a little dump truck strong and stout. (arm motions showing strength)
Hauling stuff around is what I'm about. (motion: carrying things)
When I get all filled up the workers shout: (cup hands by mouth as if shouting).
Dump me over and pour me out. (Tip to one side, or with arms outstretched and fingers interlaced, bend forward)
