I turned my twins into Legos for Halloween! I made these out of a cardboard box, plastic cups, paint, and glue of course. These were very easy costumes to make. Get your box, glue your cups on both sides evenly across from each other to make them look like legos. Cut your holes for the head and arms to go through and then paint the box and cups whatever color Lego you would like! You could make the boxes longer to cover more of their bodies for a rectangular shape instead of a square. Have fun with it! This was one of the best Halloween costumes besides the refrigerator and the Minecraft Steve that I made for my other children!
