As Steven watched the fur covering up his face except for his wet, twitching nose, he tried to understand the longer, clearer hairs that were sprouting underneath it.
"Whiskers? And a doggy nose and ears? My whole face will be like a dog's when this is over!"
But right at that moment, as if to make sure he knew he had underestimated the extent of his change, a very funny feeling traveled up from the end of his spine. It was like his tailbone popped and loosened underneath him! But if that wasn't weird enough, it started to swell. He could feel a meaty lump starting to form on his bottom. After it formed, it kept growing, not much wider, but noticeable longer. But what really blew his mind was that it started to move! He could feel it probing around in different directions until it got too long and started painfully poking into the back of his pants.
"Ouch! What is that? I haven't broken something have I? Oof! I've got to make room for ..."
He wiggled just slightly out of his pants, he got them down far enough that whatever-it-was popped out and kept growing. He tried to twist around to see it, but it was pretty far behind him, and it was twisting itself around as well.
"A tail?!" he said when he finally saw it. It was still growing longer, it was already long enough that he could see it flailing in and out of view from behind him. It was still hairless so far, but it was unmistakably the stiff and pointed tail of a domestic canine. He waited until the uncomfortable feelings of growth stopped. Then he perked his ears and leaned toward it, hoping for a closer look. Unfortunately, it was hard to resist just wagging it around like a dog does. He sort of circled himself around one way, then another, watching it swing in and out of view from either angle. He turned all the way around and looked backward into the mirror, but his tail was so long he could feel it tapping the mirror!
"This is ridiculous," he thought, so he gave up on just looking it over from a far. He started actively trying to reach it. But he had trouble timing his movements enough to catch it! He reached around one way, then another, and then the same way again. It looked like he was spinning in circles!
"Hah, hah! This really is too much!" he laughed, causing his tail to wag harder. By the time he finally caught it, he was laughing so hard that he dropped it and had to start the game again. By the time he finally got a proper hold on his new tail, it had already sprouted the same short fur he had on his face, except that the last half of his tail fur was white. Needing to give this strange object a decent once-over, he said down on the bathroom floor and held it with both hands. It felt uncomfortable to forcibly grip it like this, so he finally just let it go and thumped it against the tile floor behind him.
"So this is really my tail now," he thought. "How can I go to school with dog ears and a tail? Maybe if I turn all the way into a doggy I won't have to go?"
That was the first time Steven realized he might completely turn into a dog. If he did, would his name be Rover like the dice said?
