Your gaze goes between the bowls and the plaque several times trying to figure out which of these bowls you should eat from. It's clearly some sort of riddle meant to give you a hint on how to proceed, but try as you might you can't determine the answer. After what must be another few minutes before you grab the first bowl of oats, almost at random. You stick your hand in the bowl and shove a mouthful of the dry oats into your mouth and, with some effort, force yourself to chew and swallow them. As soon as you do the bowl drops from your hands as the walls and door before you fades away leaving nothing but blue sky and green green grass.
Your heart races and your hands clench into fists. You feel and see your face stretch forward. You nose broadens and flattens out and you can see brown hairs growing on from your skin as your face alters its shape. You try to cry out, but your mouth no longer seems fit to make human noises. As you neck thickens and a black mane stretches from your skull down to your shoulders you end up making frightened whinnying noises. You try to unclench your fingers, but they've fused together and become a horse's hooves. The top half of your body becomes to heavy to hold up, especially as your arms lengthen. You fall forward on what now are your two front legs. You give your head a shake, almost instinctively. You feel your back straighten as your back legs change into the digitigrade stance. You shake your skin, a skill you didn't have before, shortly after your entire body is covered in horse hair. The last change comes as a black horse's tail falls free from your tailbone.
Strangely, a thought enters your mind Mares eat oats... you think. It's part of an old song you once knew, but now those are the only words you remember. You close your round, brown eyes for a moment and when you open them again you're no longer alone, and no longer in the strange dream-like world. You're, in fact, in a field with a number of other horses. One of whom you're sure will eventually mate with you and give you a foal.
