Zero and Stanley continue up the mountain, getting closer and closer to Big Thumb. They see weeds growing in the area, and there are gnats biting at their skin. Blech.
Suddenly, Zero doubles over in pain and vomits up the sploosh. Then, trooper that he is, he gives Stanley a thumbs-up and they keep walking.
Stanley realizes that the presence of weeds and bugs means that there must be water nearby. Zero smiles happily at this idea and then passes out.
