All of a sudden, I doubled over on all fours in pain. I saw scales appear all over my body. Where did they come from? My feet and hands turned into paws. My five fingers became four deadly claws, my toes became three. My legs and arms became powerful muscles. My body grew in length and height, and a tail pushed out of my tail bone. My neck elongated as my face pushed out into a muzzle, teeth growing into fangs, horns growing from my head, ears becoming fans. Wings grew from my back. My eyes changed from blue to a wicked looking crimson. My human mind vanished as it was replaced by a dragon's. The transformation stopped.
"What hass happened to me? I'm overflowing with powerrr!" I looked down at my body and realized I've become a huge green dragon! Amazing!
I flew out of the house, breathing fire. This was awesome! I've always wanted to be a dragon; now I got my chance! I roared in triumph!
