As the tingling sensation works its way throughout your body, upwards from your feet, you notice that your toes begin fusing together and hardening. You find your heels pushing upward and straightening into your legs. You realize you are growing hooves, but not the solid hooves of a horse. No, you are growing the hooves of a pig.
Soon you notice your body expanding in certain areas and shrinking in others. You start to lose your balance and fall forward. As you try to pick yourself up, you notice that your fingers are also fusing into hooves and your body hair is being replaced by coarse bristles. You feel a strange sensation in your lower back as a curly tail grows out of it.
After several minutes of painless shifting you come to realize that you are a pig. Your have a long snout and pointy ears that flop over. You walk around a bit to adjust to your new form waiting and wondering when you will be taken out to the sty to wallow in the mud for the rest of your stay.
