I had an idea, and this is it.

So, the disassembly drones are corvids now, and the worker drones are small animals. Go figure.

No more sneak peek >:3

I unknowingly made the two wd's that end up murdering other wd's predators of small animals.

Ermines are a type of weasel, and opossums eat rats, mice, and basically anything that's smaller than a rat.
