(Claps) Nice chapter, its fun to see how they can be kinda used to the treatment and horror of the bad working conditions (for me, anyway xD), though I'd think the skull popping out of nowhere may be a bit surprising. You've also got a reason for your slig being nice, which is good (Most are kinda 'nice for no reason', I'm guilty of that).
Also, its possible that the worker mudokons have no reproductive organs, or underdeveloped ones. They're also unlikely to have boobies, since they likely won't be mammals (they're a eusocial species). Though that rule gets broken by dozens of people, so you can probably get off with that

There's also a post here
