I was reading random articles on wikipedia the other day and this one peaked my interest.
http://en.wikipedia.org/wiki/Shrunken_heads
Is it just me, or does that head in the larger picture look like a Mudokon? Plus the tribal meaning behind the heads and even more interesting are the sewed lips on the mouth. Now I KNOW why Abe's lips were sewed, the whole thing to keep him quiet, but it is my theory of what inspired that part of the design were thre sewed lips on shrunken heads.
So, what do you think?
