Unlike the FISH!!! in the picture, the FISH!!! in this creek are not oblivious creatures, and you are trying to catch them with your hands rather than with a harpoon.
You attempt to catch FISH!!! in a tributary of the Klamath River, with your bare hands. Of course, you fail. You then starve to death after eating grass out of desperation.
You would have scared the fish away by being too loud, anyway.
