My husband had this costume planned for several years, long before we had a child. The inspiration was a computer game he played in high school. When we found out we were having a baby, he got to work. Ryan sketched out the rough designs probably two months before Geraint was born. With so much baby stuff coming in the mail, we had plenty of boxes for him to work with, so he just had to buy a few things to make it.
The frame is cardboard wrapped around PVC pipe and held in place with zip ties. It’s a flexible form with Velcro keeping the limbs attached at the joints. The visual details are made of foam board.
