A 2008 cosplay group I organized and made most of the costumes for, based off the Channel101.com "Twigger's Holiday" web series.
The Purple hat on Twigger (Orange Shirt in the back), is a Tarzan TERK stuffed animal, with it's head ripped off. Daniel made a great Twigger.
The Mookie Brother is my real brother Kurt, sporting a custom tailored blonde wig. My hairstylist was kinda embarrassed to style the wig with it on my, but she did a fantastic job nonetheless.
Melanie did a bang up job created and being "Michelle". Everyone just loved her. The hair and the glasses, how could you not?
The Josh costume (Blue guy in front) was made using Blue medical foam mattresses, cut and hotglued to a long sleeve shirt and sweat pants. The head is made from cardboard, and covered in bright colored EZ-Foam/craft-foam and outlined in black magic marker. 12 hours of speed gluing foam is not a way to enjoy a convention. Make sure you finish your costumes before the convnetion starts.
