That's a pleiospilos! They're called split rock plants just the way Lithops sometimes are, and they are related. I have two of them. "Not to water" is the thing to do right now, it's growing its new leaves and it is just like lithops in that it absorbs the old ones, so it doesn't need any water while it's doing so.

Edit: Oooo, never seen one pupping like that. I had thought they would divide the heads the way lithops do, but that sure looks like some kind of pup. That's all sorts of awesome! Good luck with it.
