Nack the Weasel is a fairly obscure character from the video games, only appearing in 2, Triple Trouble and Sonic the Fighters, but he has a pretty large and loyal fan-base, even though he's only been in the comic books for the past decade or so. Nack started off as a Shadow, I sanded off his spines, ears, and muzzle to make room for all of the weasel bits. The hat and tail are scratch built from foil and polymer clay.
