In chapter 2, You'll find some totems near the huts and also symbols on the top front side of the hut. these are marked in your journal and can be view anytime by pressing
. You'll eventually end up in a hut where a pillar with totem faces(Puzzle) on it and also a torn paper on the table beside the pillar. I've added some images for the totem puzzle and torn page. can't add the image directly from Xbox live to TA (some sort of glitch happened on my end I guess) so added it through Imgur. check the link for images.
Note: After I completed the puzzle, the Mouth part of the totem is moved a little bit. I tried to take a screenshot with a cross angle to show alignment.
