Thanks Lampion, you always seem to find all the things the rest of us overlook.
I found a pic that interested me. It's one of those shrines that Abe chants to to change a normal mudokon into a 'Tomahawker':
Above the shrine is a painting or engravement of a symbol for a Tomahawker, this lets the player know what the shrine changes mudokons into. Unfortunately no more of these symbols are available to us at this time. There is a LED sign giving instructions next to the shrine in red letters, which I thought was unusual considering they're in native territory. The counter (green number) must have some relevance to the shrine or Abe's amount of spooce. In this picture the counter reads "5" but in another pic that shows it after Abe has begun chanting, it has changed to 0. I think this counter shows the amount of spooce Abe has. I believe the amount of spooce for transformation is different depending what the shrine changes mudokons into. Changing a mudokon into a Tomahawker must therefore require '5 spooce' which is probably stated on this, or another, LED sign.
Just thought I'd share these observations with you all. Would anyone else like to share their opinions or other comments?
