So I've been spending 2 hours a night trying to get this guy to spawn. Most often, I used the kill the dwarf skelly before it despawns method - no pop. So I just clear camp, clear camp, clear camp, clear camp, clear camp, clear camp POP. His PH is the putrid skelly right in front of the tree, next to the downed staging thing. I didn't kill the dwarf skelly or it's PH (the sitting putrid skelly) once. Just my recent 2 cp.
