The Doctor shivered on the floor of the TARDIS, exhausted tears sliding out of his eyes. Is this what death is like? Death, decidedly, stinks. Slowly, The Doctor managed to regain feeling. Slowly, painfully, he forced his eyelids to part, opening until the interior of the TARDIS was plainly visible. So this was the new TARDIS? It looks... ugh, never mind what the TARDIS looks like, the update can be evaluated later. Right now, a splitting headache was to be dealt with. The Doctor groaned a pain-filled groan, and reached up to the console to pull himself up.
"AH!" The Doctor immediately recoiled, pulling his new appendage inward, then, remembering it's appearance, tried to distance himself as far as possible from it. It was a marvel to look at. It was not a hand, but rather, some sort of hoof. It was a strange sensation, being in control of an entirely new body part. The Doctor began to inspect his other hoof. Then his other other hoof. And lastly his other other other hoof. "Now this is surreal." The Doctor propped himself up on all fours, struggling to maintain balance. "I... don't know how to walk." He attempted to try his right hoof first, ultimately falling forward and to the right a bit. Regaining posture, he attempted again this time succeeding in placing one hoof forward in an awkward stance. Next he brought out his left fore hoof, overextending himself and slowly sliding down on to his belly. Mumbling to himself he once again got standing. Right front, right back. Left front, left back. This he continued until he could walk at a level of satisfactory ease, doing a few laps around the new console to prove to himself that he could manage, and to work any kinks in the system.
Having navigated his way to the wardrobe, he examined himself in the mirror. This was just weird. All kinds of it. He noted his features. A chestnut coat, gentle on the eyes. Deep brown hair, no, mane, spiked in a rather stylish fashion. Eyes that were a rather nice shade of blue, and... what is that? He brought his rear center-stage to examine something on his flank. What was it? It appeared to be an hourglass, but why? He shook his head of it, determined that he'd discover it's purpose at a later point in time. He then turned to his wardrobe, "What do equines wear?" He strolled around the room until he decided that it would be unfitting if he wore clothes, it'd be strange. As he was about to leave he noticed something in the bin. A collar, it looked like, perhaps torn from the original shirt. Picking it up between his hooves he lifted it over his head and onto his neck. He laughed at it a little bit and then thought a little deeper. An idea clearly sparking he rushed off and returned with a red tie, fixing it (though with extreme difficulty) around his neck. "There," he spoke to no one in particular "it almost looks sensible." He smiled a smug look of satisfaction and trotted out through the corridors and into the main room once again. Eagerly, he pushed open the loud doors to his travel capsule and basked in the sunlight that flooded his face. With a wide grin across his face, The Doctor stepped out of the TARDIS, and into the village of Ponyville.
