This guy is just a puppet prop that we used in our skit, but I'm very happy with him and since he was technically a character in himself, I'm making a Costume entry for him!
His hat was made by Pancake Mix, but the rest of him was made by me. He's comprised of upholstery foam covered in panty hose which was painted with acrylics to get that rough look, with craft foam for the teeth and a halved styrofoam ball for his eyes. There is a small wire inside his bottom lip to shape the mouth, and the jaw is worked by a strip of elastic under his chin rather than by the puppeteer's hand inside his head.
He was used in "What Have You Done?" at Anime Matsuri, which won Best in Show!
