Being clear-white and somewhat attached to a white piece of paper, the plastic rodent thingy can be hard to find. This is actually a chunk out of a plastic tub that we were using to transport stuff for a concession stand that we were running for a little league association (well, we were actually doing it for us...). By the end of the second season, it was pretty well beat up and cracked and a big chunk of it fell out (at which point we retired the tub). One of the students, grabbed the chunk, decided it looked like a small animal, and filled in the details with a sharpie (he even signed it). Then he hung it up on the wall...it has no formal name, so we call it the plastic rodent thingy.
