You wake up slowly, aware of some confusing things. You are outside lying on the ground, except your head is on a furry, oddly shaped, and very smelly pillow. Someone is stroking your head gently, and making curious grunting sounds. You feel wonderful and very strange at the same time. Then you open your eyes and see the fearsome face of a Bigfoot staring down at you!
With a roar of fear, you twist away and scramble up to your feet. Your huge, hairy feet. At the end of huge, furred legs. The monster is sitting on the ground, watching you calmly. You realize it was stroking your face with your head in its lap. Reaching up, you feel your own protruding face and fangs, and understand that you are a Bigfoot, too.
An attempt to speak comes out as a grunt. You try again, but find that your vocal chords do not work like a human's. The other Bigfoot rises slowly, its face unreadable. It is also male, pretty impressively so, and the same height as you are. In fact - you look down at your huge, furred body and then back at the other Bigfoot. The two of you appear to be identical. You remember the footprints in the grass, the ones you stupidly followed. This must be someone who got changed as well. But how? And how can you get changed back?
The other Bigfoot reaches out and takes your hand, then tugs you towards a break in the trees. You let him lead you to a small, still pond. It only takes a moment to realize why you are there. He moves tot he edge of the pond and looks down. You do the same, and see his identical twin brother reflected back. Whatever power, or magic, you encountered seems to have made you into the same creature. You wonder who it was? Who HE was. You are both monsters now.
You are amazed at how calmly you are taking this. Being a Bigfoot should be terrifying, but though you are aware of being different than before, this body feels good, almost normal. Something is happening in your head, you realize. That is a little scary - you do not want to lose who you are, but you don't seem to have any control.
Then a sound from the forest makes yo both look up. Someone or something is coming!
