They're more like really really shiny furries. If this bugs people, I'm really sorry, but once I get started shading like that it's hard to stop. At first the squirrel was gonna just have a shiny dress, but then I got a wee bit carried away. Anyway, it was fun. Oh, and the colors were just a little too bright so I made it look like an old photograph that just happens to be in pristine condition.
