My Guess is he spawns close to the Bird house in SK, then, paths North thru Paw, all the way to the NK Bridge, then runs back down the wall to the shadowmen - I also believe the low level Mobs such as lions and wolves are PH for him.
So, if you want to see him , kill all the lions and crap you see around the Bird tower closest to the hermit and towards the KFC house from there.
I have seen an killed him about three times in that area. At the time, we where medding by the bird tower , and lions kept jumping us, thus we had to kill them.
