Kponyungo masks are used by male Poro members at funerals wearing baggy, mud-dyed costumes. The Poros portray powerful spirits escorting the deceased to the other world, thus protecting the community from supernatural danger. The main features of these masks are the eyes, large mouth, and ferocious teeth of a crocodile; the snout of a hyena; the twisted horns of a ram; and the slender, arcing horns of an antelope.
