Cardboard Boxes, Yellow and Blue Spray Paint, Plastic Bucket from WalMart and Tuna Can is all you need for this Lego Boy Halloween costume. The hardest part of this costume was getting the head right with the plastic bucket. I used Pringle cans to give the head a curved shape near the neck. Model spray paint was needed to get the paint to stick to the plastic bucket.
My son loved the costume and everyone at school thought it was the best!
