The poison worm is mostly done. It's covered with ooze and leaves ooze trails, which I've never seen before, so I don't know if that will cause any problems. I expect not, though: The ooze is weak enough as a poison that even barefoot dwarves shouldn't be too bothered by walking over it, and indoor cleaning works pretty well now. You'll probably still want to make sure that these guys are kept in a closed pen, though, so you don't have ten billion cleaning jobs all the time.
I actually think the effect is pretty neat, and if it goes over well I might make a few color morphs of them with different types and strengths of poison.
The poison can be reduced from ooze to gel, but the gel can't be denatured yet, and the mod doesn't include a way to apply the poison to enemies - I need to read up on what others have done in that vein. I also haven't given them poisonous meat yet.
