Oh Great... Plagued Magnataur!

Tinky and I came out here stalking some old magnataur. Apparently those caves up there are where they go to die. Of course, we had no idea that they were going to get plagued when they went in there. We can't have plagued things just roaming about; it's not healthy. Say, why don't you put down a number of those things while I figure out what our next step should be?
