Karma. Best answer ever.

But are these the only ones? Do they reproduce? Do they die? Do they split themselves into two now and then? Or maybe one hibernates in a trash heap and three come out in spring?

I figured they'd breed like fowl or insects in some bizarre reproductive evolution and randomly shit out pseudo-egg-like lumps to be fertilized, and then out come the little ones to scatter and eat whatever's in sight.
