Adult professional skaters under five feet tall were found to perform inside the bulky Peanuts' character costumes. The only air in my costume was where my eyes lined up with Charlie Brown's mouth. It's amazing I could skate at all. By the way...when Charlie Brown's head came off, I had a very "bad hair day!" Also...use your imagine to try to figure out how hard it was to skate (and do small jumps, spins, and footwork) on a little stage in the dark in a character costume with no air!
