You were fishing in the Everglades of Florida. Today you were out on a community project to hunt invasive Burmese pythons.
You spotted one of those dang wrigglers in the water and steered your boat over to it. This was a particularly huge one, probably the largest you've ever seen. Suddenly, a massive shape lunges out of the water and grabs the snake, before diving back down in the swampy water. You take out your gun, unsure of whether or not to shoot.
