And yet another person falls to "hoggyism"...
1. I wouldn't recommend it. If you use crushed english walnut shells, that sould dry the place up a bit, while also having a burrow-able suface.
2. I've seen standard albinos and a high-green for $100 (but that's really cheap), and "oddballs" (unusual for a Hogger's pattern) for $60. You want to see a pastel? Well if you visit my profile page, you're looking at one! (the picture on the right).
P.S. Go for "Hoggerism"!
