My son wanted to have a costume that was unique so we decided to make his costume. He wanted to be a video game so we picked the Claw Machine and we got started. This was a lot of fun to make, we used a large box for the costume covered with vinyl and poster board. The windows are made from plexiglass from the local hardware store, then we used a old video game controller in a small box on the front and zip tied it to the large box.
We added battery powered lights on the inside and put a foam claw hanging down from a chain. It has arm holes and straps made from black duct tape to help make it more comfortable to wear. It has an opening on top for air and for when he had an itch. After we added some stuffed animals we were done. We used a lot of hot glue, black tape and time but he loved it so it was worth it.
