You lose balance once you've grown taller than the trees, and started to wonder when these changes were going to end. However, that was forgotten, when you felt your own body elevate itself to a form that is more suited to be on all fours, when your tail got longer, and your butthole began to form under it.
Next you feel pain in your own neck as you felt it stretch as long as a giraffe's, and your ears started to get pointy. Two sharp horns began to poke from your skull while coming in between your ears, and mane. Two sharp edges came out of your back as the horns were forming, and you felt your own tongue come out feeling long, while some of your teeth started to fall out. The scales on your body cover you, while your teeth get replaced with sharper, and more powerful teeth perfect to bite into anything.
