You look to the fairy, who still has that impossibly smug grin on her face, and you take a decision. A sudden decision, perhaps more than rash, but you know it's for the best. Just looking at the fairy's face confirms it. She's the portrayal of smugness. Meanness incarnate. Pleading with her to change you back will achieve nothing. She will use her magic to humiliate you again and again. You will end up in an even worse fix than you are now. That's for sure. No doubt about it. Better try your luck elsewhere. Certainly not ALL denizens of this enchanted woods are as mean and nasty as this awful fairy. There should be at least one to be nicer and help you out. Fairies must not be the only ones to perform magic in this place. So with one look of pure hatred towards the fairy, you turn around and run away. At full gallop. You leave this stupid fairy behind you, and for good, you hope. And your muscle memories allow you to go fast, very fast, barely knocking over things like stumps, fallen logs or boulders. You dart around the trees as if you had done this all your life. Ferns and bushes brush past your flanks, legs and hooves as you are intent upon putting as much distance between the fairy and yourself. So you run, and run, and run, still at full gallop, until you are exhausted and out of breath. You've halted in a clearing, near a slow river. You were so concentrated upon your flight that you didn't really look around your surroundings. Now you do and indeed the place sounds quite restful, with its birds chirping and the animals frolicking. The violets, daisies and soft grass are very pretty and indeed quite... appetising. They must crunch under the teeth and the flavor must explode in the mouth like... You shake your head, appalled. No! What are those thoughts?!!? Are you starting to think like a horse? To want to act like one? Hell, no! You don't intend to stay like that! No matter how pretty your coat is or silky your mane and tail or... You look down at yourself and notice that your crotch is missing the impressive privates of a horse. Damn... Looks like you are still a female... One more thing to remedy to... At least being a male unicorn, you would have had the pleasure of having an enormous penis and of seeing it coming out of its sheath and proudly erect. You sigh. Yes, this place is pretty but you are on the lookout for a creature able to perform magic and at the moment, there is none...
That's one a noise startles you.
