Chubbs' school held an environmentally-friendly day, where they asked the parents to create costumes for the kids, using recycled material. And Chubbs went as a very loose interpretation as the Tin Man. I used a paper bag for his hat, and cardboard boxes for his armour over the arms and legs. Unfortunately, the tin foil that I covered the suit with, is not a recycled material :(
He loved his suit so much, that he stayed in character and went around walking robotically all the time in school, and also kept his costume on almost the whole time, until he had to go for his gym session.
