The zoomans live in an idyllic little paradise (at the very least we don’t see much of it). They even seen to enjoy the choosening, so aren’t fazed by the one downside to their utopia (well, two if you count the lack of fry bits).
Even after Heartbreaker Greg dropped the big bomb on them (in just about the least-gentle way he possibly could), they’ll probably bounce back with the help of the Famethyst—the shipping must flow.
Will we see them again? It’s hard to imagine so many unique character designs being thrown out, but what will become of the zoomans?
