Also, I suggest ( in my theory ) that you start out with Applejack or Fluttershy. With Applejack, you'll only grow hooves. With Fluttershy, you'll grow wings, which appears to feel awkward. With Applejack, you won't be as hyperactive as Pinkie Pie, so you don't romp around and make a ruckus, and you won't feel awkward growing anything else but hooves. With Fluttershy, you'll feel wings grow, but you won't try to fly unless you have to.
