Super easy toddler bulldozer halloween costume! Diaper box painted yellow, flaps are cut and painted to form bucket. Dollar tree gift boxes painted black for wheels, black bulletin board boarder for track. Black cardboard for grill and inside bucket. And two stick on touch lights from dollar tree for headlights. Black ribbon for straps (cross in the back to keep from slipping off shoulders). CAT decals and done! We had a smoke stack from a paper towel roll but it kept coming off.
