Choo Choo Train Costume

This is my 3.5 year old son John. He told us he wanted to be a TRAIN for Halloween. So Sunday before Halloween my husband made him a train. Using a diaper box as the support he built the train form around it with foam board. He used spray paint, duct tape, metal tape, glue gun, and cotton balls/fiber fill. Elastic is going across his shoulders for support and a metal hook is on the back to hold his trick or treat pumpkin.
