There's a reason for all those Tillinghast Field warning stickers. Fail to pay attention and you could find something like this gnawing on your flesh.
A quick and dirty shot of a critter I was working on over the weekend. The skin is latex over a silicone core and the teeth are epoxy resin. The gooey, chunky slime is cornstarch and water that was heated to boiling in the microwave and then cooled. Yes, it's essentially gravy. Heh.
