In first few moments you try to deflect the choice of the barber, but you soon accept it, since you really dont know anything about being a horse and this could give you some interesting insight. Barber informed you that if you want, he can change you back in a month. To which you replied with "We will see about that.", as you admired muscles on the body of the stallion you were transforming into.
It didn't take long before your transformation was accomplished. After your lush mane formed on your, now, fully horse body, the barbershop dissipated, and you ended up on four legs outside a weathered barn. You can feel something on your back - it is the teenager you wanted to become at first. Even though he is quite big, he is but a pebble for my massive body.
The body you gained feels amazing but lacks ability to view some colors, although your sight is 20/20. In addition to that you gained better sound and smell catching capabilities. Since you just became a horse, this body is still strange to you. But as the boy dismounts, you feel content with your current situation.
The boy is your master - you recognize his smell, and know you have been his for several years, ever since you were a foal. The barn is where you live. Something else seems strange, though. You can't quite place what the difference is.
The boy moves around and opens the barn door. "That's enough for today. Go on in to your stall, boy. I'll bring you some oats."
Oats?! A quick shake of your head makes the boy think you have ear infection, but he soon realises that your reaction ensued as soon as he mentioned oats. It seemed odd to him since you never said anything about oats until now. He doesnt bother with that though, since oats are tasteful and nutritional food.
You seem a bit disgruntled, but that mood soon disappears as soon as you realise how tasty the oats are for you, as a horse.
