Rabbits, oddly are the same as cats or dogs, I might alter that. Parasprites have a litter size of 10 to 20, but it's not possible to change the frequency. They only yield skulls, though, so pretty much the only use for them is to get one male and 48 females, stuff all the offspring in a cage and set it to explode on a diomedian siege. Not that I'm going to try that, 720 parasprite all at once isn't going to do my computer any good.
I honestly hadn't given much thought to the headless kamikaze horses. I suppose if I give them bomb hooves I'll have an excuse to make them pegasi, or just do that in addition.
Clear glass or obsidian glasses is a nice idea. What I'd probably do is make them like a mask, and have one new item for each colour of lens, that way the frame material can be dynamic, ☼whip vine cookie pair of sunglasses☼ or whatever. I'm sure someone was working on various bits of clothing like monocles and such a while back, I wonder what happened to that.
