This mod adds parasites. More specifically, it adds leeches. I won't explain how or what they do, but they can be picked up via right click, so maybe try that.
Might add more parasites but who knows.
This mod has nothing to do with Scape and Run: Parasites or anything like that.
P.S. This is only on Curseforge. I will not put this on anything else. Probably.
Not like anyone cares though.
Also made using MCreator.
