I have found some very intersting information about people known as Keraki Papuans. The link is worth exploring more by clicking on Keraki at the top of the page. To cut if short the first beings {Gainjin} returned the the sky all except Bugal the snake and Warger the crocodile who still haunt the bush today. So I am starting to form the idea that it is indeed a snake. With very little contact untill 1920-39s it looks very much like it should, if it is that.
