Wheeeee!
You plop down on your butt and start sliding down the cave passage. It's a long way down! You come screaming out of the narrow slide into a larger chamber. Luckily your high-friction method of descent was enough to keep things under control. You gain +1 butt blister! You stand and realize you aren't alone in this new cavern. There's a huge spider! Or, a spider-lady? Her bottom half is a fucking enormous spider, but her top half looks like a normal enough person.
