As you look over your mostly jackass body, you attempt to say "ugh, this sucks." The only thing that escapes your lips is the ragged bray of a jackass. It suddenly dawns on you what you are quickly becoming. Should the changes become complete, they could very well be permanent. You'll never be able to drive a car ever again. Or to play video games. Or ride rollercoaster. To love, to eat pizza, to communicate; or to generally live a free life as a human.
This quickly frightens you out of your revery. You again make the attempt to speak. Once again, the only thing that comes out of your mouth is a typical bray of a jackass; stronger this time. You can't speak at all!
You attempt to get up, and you come to yet another realization: You cannot stand, except on all fours! "Screw it! I've got to get out of here!" you think (attempting yet again to speak.) "Hee-haaw! Heeee-hhaww hee-haw!" you actually state!
You get up on all fours, and as you do, suddenly your stomach begins to expand, and in-rush of air comes through your nose and your mouth. As more and more air enters your lungs, you have a long, high-pitched "HHHHEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE" followed 30 seconds later with a deep baritone "HHAAAAAAAAAAAAAAAAAAAAAAAWWWWWWWWWWWW." Suddenly, breathing is no longer difficult. It seems your lungs have grown into the lungs belonging to a donkey. Your stomach has become that of a slightly overweight donkey. It seems your internal organs have completed their transformation. You look at yourself in the mirror, and see you face and your neck mostly intact, but the rest of you is all animal. And an overweight one at that.
"Great. After dedicating myself to a lifelong pursuit of healthy living habits; eating and spending time in the gym; with my six-pack abs, this is what I am going to be? An ugly, nasty, overweight beast of burden?"
"NO WAY!" you attempt to say, and once again, you can only bray. Which actually sends you into another panic. Heart racing, getting hot, as your large hairy body begins to produce the sweat (and the stench that comes with it) of a large barnyard animal, you can now take in the scent of your own body.
You decide to ignore that for now, and use this new-found rush of adrenaline to attempt to kick open that door. You attempt to take one good swipe at the door with your right leg. However, not being used to such a body as this (and without the instincts to use it,) you end up barely touching it, and begin to fall back onto your right side again.
Landing with a loud "thud" on your side, suddenly you feel pain throughout your body, and you become even hotter. This time, you can feel your neck stretching outward, and you feel a familiar tugging at your ears. They are actually becoming even TALLER.
However, the stretching of your neck distracts your attention, and begin choking. But rather than cough, all you can do is bray a long series of "Haawws," getting deeper and deeper with each growth-spurt throughout your body.
With a moment of mental clarity, you think: "Jeez, how much larger am I going to get?"
Looking up from your pron position on the floor, you notice the room seems slightly smaller. Looking over at your sides, you can now see your belly really protruding out, and your legs appear even further away.
Suddenly, you get a massive headache. The only thing you can do at this point, is to close your eyes. You attempt to moan, and once again, you can only bray like the jackass you are still becoming. The headache is so massive, it feels as though your head is swelling. Which, in reality, it really is. Your face is pushing out, and your forehead is sloping. Your nostrils flareout, and become very large. Your teeth square off, becoming large yellow blocks. Your tongue thickens, becoming slimier. With great globs of saliva. Your lips thicken, and become black. All the while, white hairs around your nose and mouth poke out, as it fades to gray hair covering the rest of your face. Finally, your mane grows in, complete with a black swash of hair on your black, forming a cross.
Now what?
