As fate would have it however. The elder and the two younger, encountered troubles of their own. As it turned out, their truck, which they didn't drive for months at a time, wouldn't start (the 'eco-friendly' gasoline in the gas-tank it turned out did not have a long shelf life). Forcing them to walk. They considered using magic to change shape and simply gallop or fly there, but with the chaotic forces accidentally unleashed by the younger pair, this could lead to some unhealthy consequences. As it was . . . they wouldn't reach their destination by mid-morning, and the Butlers themselves would be long gone, along with a few others who now carried the change, assuming they managed to pick up on the Butlers' trail at all.
Joshua at his desk meanwhile, stayed to his duty until his shift was over. He looked at a picture of himself and his family, the look of a human being a moment confused him, but the more he looked at it, the more the picture itself changed to show the same naked anthromorphic horse that Joshua had become. When time finally came for his shift to end, he didn't even look at his torn up uniform, and headed off to his own bed. He passed by Jim who was the day shift. Jim looked at Joshua in shock and alarm for a moment, wondering if some weird trained circus horse had gotten in, before his confusion and fear dissolved.
"Heeeey Jim."
"Heeey Jooshua." The two slurred at each other as Jim's body instantly began to change, his body becoming too big for his uniform that tore itself apart, leaving his shoes behind to the clop of his hooves, as his hair became a mane and his face and neck lengthened. His tail swished behind him.
The next morning of the desert motel was remarkable 'normal' for the oblivious furry nudist. None of them had put much if any effort into covering themselves, though the mares had put on jewelry, and their purses, and the stallions wore belts that did NOTHING for their modesty but held their keys and wallets. The motel staff wore white collars which had their name tags pinned. Though all of them were thinking with annoyance at the small beds and small doors.
The colt and filly of the family of four happily played in the motel swimming pool under the super vision of their parents.
The Bulters, exhausted from a night of love making, exited their room relaxed and rejuvenated. They saw nothing wrong in the mirror that morning, and when Nathan looked at his driver's license, not only did his picture change, but his height, weight, and other details all changed to match his new form (and the Sex changed from M for Male to S for Stallion).
None of the naked anthro horses gave each other a second look, though all of them felt a strong sense of 'belonging' and 'safety' that was inherent with a herd species. And the Butlers were soon driving off to the nearest dinner. A traveling salesman who stopped at the hotel a while later was shocked at the sight before him, for a moment thinking he had caught sight of an anthro-con, before his expensive suit lay mostly in tatters behind him without a single thought to it, and the newest bipedal horse calmly checked into the hotel, being ever so slightly more polite than he'd have normally been, a sense that it would be like being rude to family.
