It’s difficult to find any in-depth information about the Chimbu tribe from Papua New Guinea, a tribe that paints their entire bodies in the semblance of a skeleton.

They are from the Western Highlands of Papua New Guinea, the Simbu or Chimbu region, and apparently their extensive and beautiful body paint originated as a way to intimidate their enemies.
And I can imagine that watching a mass of tribal zombies coming to get you would be intimidating.
Simbu is a province with limited natural resources and very rugged mountainous terrain. The economic progress of the province has been slower than some other highlands provinces.
