It was exactly midnight. You were out camping in Yellowstone National Park with some friends, near the strange shack in the woods that had been there for centuries. You were all investigating the missing animal situation, though you had to take a break because you all were exhausted.

From the shadows, you saw two glowing eyes staring right at the fire in contempt. Whatever was there hated your presence and quite frankly wanted you to know it. The thing, whatever it was, scurried through the undergrowth, snatching one of your friends' sleeping bags and fleeing before you could spot its full form.
