"I know! My favorite animal is a dragon! I've always wanted to be one!"
Just then, you double over on all fours in pain. You then see that you have green scales covering your body.
"What the.." you start to say. Your hands and feet turn into paws, fingers becoming four claws, toes becoming three. Your legs reverse themselves as you started growing bigger and bigger. A tail rips through your pants as your clothes are reduced to shreds. Spikes run down from your head to your back, which lenghens. You neck elongates, face pushing out into a muzzle. Fangs rip through your gums as your old teeth fall out. Your eyes change color to crimson. Suddenly, two bat-like wings rip through your back! Finally, two sharp-looking horns pushed out of your skull. Your voice becomes roars, and your human mind fades away and is replaced by a dragon's.
You stare in shock at yourself. You've become a large green dragon!
"Thisss issss cool!" You say. Filled with exhiliration, you fly up to the sky, blow a jet of fire into the air, and meet the other dragons.
"I'm going to stay this way FORRREVERRR! Drrragons are immorrrtal, anyways, so I'll live forrreverrr! Awesome!"
You fly down to the valley where the other dragons are. They welcome you into their clan.
You begin your life as a dragon.
