Thinking ahead, Nathan carried the Chronivac to the garage and placed the device on his dad's work bench. He'd seen pictures of reindeer, and they looked big. He figured he would need some room to move once he changed.
After he clicked the ENTER button to initiate the transformation, he noticed dense hair sprouting on his arms. The hair continued to spread over his entire body, eventually becoming a thick, uniform pelt of brown and gray fur. A shaggy white fringe of fur extended from his neck.
Pressure increased on his spine, forcing him to assume a stooped stance that eventually led to the traditional four-legged mobility of the typical large quadruped. He shook his head and felt the weight of his massive antlers, which raked the concrete wall of the garage. He didn't like the enclosed space and his reindeer instincts began to assert their unease at the situation.
"This is weird," he attempted to say, instead producing a low bellow that bounced off the garage walls.
Once the change finished, Nathan took a few unsteady steps across the concrete floor of the garage. It felt strange, and he also detected a strange noise. In addition to the clatter of his hooves, his feet made a loud clicking noise due to a tendon slipping over the foot bone. He felt strong and massive while at the same time his instincts kept him timid and tentative in the unfamiliar terrain of the garage.
His nostrils flared and he smelled harsh chemical scents that further disturbed his reindeer sensibilities. He had no means of determining exact details, but as a male reindeer he stood and weighed almost 400 pounds and stood a little over three feet at the shoulder.
One distracting discovery centered around the fact that his human intelligence found itself warring with the powerful instincts of the male reindeer. In a moment when the cervine instincts won out, Nathan felt his large penis release a torrent of reindeer piss on the concrete floor. When he looked at the puddle he had produced, he noticed something else. His vision registered the urine differently from the surroundings.
"Wow! Am I seeing in the ultraviolet?" The geek-inside-the-teenager wondered.
He found the old Christmas chestnut about Rudolph playing and re-playing in his brain as he enjoyed the sensation of an extremely different body.
Before he accomplished much else, though, he wondered about getting back. He moved his way to the work bench. How the hell was he supposed to operate the device now?
