Bear stores the chunks in a safe place, then starts making his shelter along the riverbank. This is by far the coolest makeshift shelter I've seen so far, even cooler than when he gutted a camel. IT'S A FREAKING HAMMOCK. I think the camera crew is envious for once, because Bear's hammock beats the hell out of their lame-ass tents. He makes it entirely out of vines and bark and manliness, and it looks like the most comfortable thing in the world.
