Pop the Weasel, on the other hand, is made out of toughened rubber. His frail little body has to withstand a lifetime of door stopping. Inside the mold of the body, is a water-filled sack containing a goggly, bloodshot eye. The eye pops out, whenever he's squished under a door. And unlike real roadkill it's something you'll want to take home and cuddle. We've tried to make Pop and the rest of his roadkill chums as close to the real things as possible.
