I'd just like to say, before I close out the CREEPY #20 week, that I have my eye on a couple of cheap CREEPY #20s in their "brown state" that I think I can get for about $15 total, shipped.  I plan to experiment with exposing them to sunlight and to a UV light source (sunlamp) and see if they turn green over the course of a few weeks (or less) or not. I will edit/update this post with the results of my experiment(s), if I actually go through with them and if I discover anything interesting,
