Never underestimate how far these things can jump! I flew with my argy around the Redwood during a metal run and I spotted one of these a good distance away on a tree. Figured I'd give it a wide berth and go around it via the swamp. I'm smack in the middle of the swamp as high as the Redwood treeline and the next thing I know this thing jumps me off my argy and pinned me to the swamp floor and murders me and my argy who was on aggro. In my death throws I saw that it was at level 95. Like an OP homing missile they are when they leveled up. Now I use the coastline as my flight path to metal runs on the peaks.
