He was still concussed when he went to find water.
That was two days ago.
He's tried retracing his steps, zig-zagging and just looking for any place he recognised. The speed of the days don't help. Everything changes so quickly, and now he's running low on power. At least he's still got some of that bizarre delicious fruit.

He ended up looking like a knight. He even looks like he could be riding a horse.
