I'm talking squishers, shagdaws, grunts, scorpees, steel blocks (because I would imagine steel blocks are the only factory-made mob that Moonchyllus would allow), you know. Would be pretty cool to read about their biological information and stuff in the zoo as well, plus it gives all the mobs more character.
Of course the mobs won't walk in squares. Instead they'll stand there, and you can talk to them like you would NPCs. Heck, there can be some animals that you couldn't fight in the game in there.
Speaking of mobs, I had this idea where Moonchyllus would keep Xantis' forces locked up as live food for carnivores like Scorpees and Grunts.:

Thought it would be cool. But yeah, there's that.
