Nathan's mind kept being solely focused on the Chronivac held by Bobby. He decided to charge head on, and foolishly gripped his leg in order to climb it, without caring about any other consequences than having to be condemned to a life stuck in a animal husk.
Bobby went from admirative of the machine to downright startled by his pet : even though he was his master, rabbits could easily turn against their owners for various reasons, and he did not want to take any risks with that.
Jumping on his bed and holding his scratched leggings, he watched as the rabbit desperately attempted to climb the mattress. But it proved to be hard for Nathan, due to the distance between it and the floor being too high for him.
Not willing to spend an unpleasant moment with such an enraged animal, and curiosity still getting the best of him, Bobby simply scrolled through the options before pressing the device on the go. Again, emissions hit Nathan, who fell on the floor.
Bobby watched, fascinated, as the rabbit grew far more larger than before. As he reached half the height of the teen, he took on a more yellowish tone, his fur brightening and intensifying in thickness.
Nathan, seeing his whole body changing again, got up and tried to hop and snatch the Chronivac, but clumsily fell when his legs no longer supported him, painlessly contorting and reshaping into bigger hind legs, ones of a canine. He looked at his hind paws as they morphed the same way, along with his pelvis and genitals.
He grew unsettled, having seen his transformation being realised halfway, having felt his puffed cotton-tail exploding into a endlessly longer and bushier one, having witnessed his front legs and paws submitting to the same curse than the rest. The only that had remained intact (for a rabbit, that is) was his head, oddly out of place with his body of a dog. But soon enough, the rest of it followed rather quickly.
As his neck got engulfed in light yellow fur, his muzzle pointed more and more inwards, herbivorian teeth sharpening to a meat-exclusive diet, snout catching more and more scents and tongue sloshing out in preparation of future drool.
Nathan felt dizzy as his skull crunched a bit, flattening, as much as his eyes squished and changed for an almond type and color. His ears were last, and while they did not flop nor disappeared much, they remained perked up and grew big.
Nathan's mind, who went through the whole process and had a hard time remaining itself in spite of the consecutive changes, finally gave up and receeded to a much doggish display and mode of thinking. He was no longer a rabbit or a mouse, even less a human, but rather a happily barking Shiba Inu, lovingly staring at his owner Bobby, in awe of what the device had accomplished in a few seconds.
