The Vaporeon dashed into an alleyway and stopped to catch his breath. Why had he thought that sneaking into a human city was a good idea? Sure, he’d always been rather curious about what happened in them, but he was a wild Pokémon and had no interest in changing that anytime soon. But unfortunately for him, he’d encountered a trainer who was particularly fond of Vaporeon, had a large supply of Pokéballs, and simply would not quit.

Luckily, the average Vaporeon was significantly faster than the average human and the two of them were no exception to that rule. Even so, he was tired, and didn’t know how much running he had left in him, whereas the trainer seemed to have positively boundless energy. Still, this seemed to be a fairly good place to hide and catch his breath for now.

As long as he was here, he figured he may as well look around the alleyway. This was one of the things he was curious about, after all. And indeed, he’d never seen anything quite like this alleyway before, having been raised among trees, lakes, caves, and such. But in particular, one thing in the alleyway stood out: A small pink sphere.

He approached it to get a closer look. It was smooth and shiny, yet clearly not a gem or the like. And whereas the alleyway had a very interesting scent, this strange orb definitely had a much more pleasant one, far sweeter than he’d ever smelled before. Driven by both that and simple curiosity, he couldn’t help himself. He opened his mouth and licked the orb. Then, having confirmation that it tasted just as good as it smelled, he put it in his mouth and gently bit down, testing to see if it would be soft enough to chew.

Despite the hard outer shell, this stuff was quite soft it turned out! And even more tasty once one started chewing. And so, he continued chewing this strange new food, wondering how he could perhaps find more of it. Were they commonly found in alleyways like this? Or would he have to sneak in somewhere to get more? Even despite the risks, he simply had to find out!

But that would have to wait. He heard footsteps approaching fast. The trainer, no doubt! Thinking quickly, he decided to use Acid Armor, his form melting down and becoming, to the untrained eye, indistinguishable from a normal puddle of water. Surely this would work as a disguise! But in his haste, there was one thing he failed to notice: His body wasn’t the only thing that turned to liquid. Somehow, the gum had also melted with him.

Soon, the trainer came into view. It was difficult to see as a puddle, but he could tell the trainer was there. The trainer had stopped for some reason. Perhaps to catch her breath? He waited patiently, thinking the trainer would leave. However, instead of leaving, the trainer slowly approached, seemingly trying to sneak up to him. It was at that point that the Vaporeon realized how poorly thought-out his disguise was. If this trainer was so fond of Vaporeon, it made perfect sense that she’d know about Acid Armor! Not only that, but it hadn’t rained for weeks! There’d be no reason for a puddle to be there in the alleyway naturally, which left only one logical conclusion...

However, the Vaporeon wasn’t ready to give up yet. He wasn’t able to hide from the trainer, but perhaps he could scare her off. And so, he rose up again, his body reshaping back into a solid Vaporeon form, before unleashing a Water Gun at the trainer’s feet as a warning shot. However, unlike the clear blue water he’d expected to come out, for some reason the water came out pink. Nonetheless, he did not hesitate to turn tail and flee after firing off a Water Gun attack. He could ponder why the water came out pink later, but for now, escape was top priority.

The trainer, undeterred, tried to give chase, but noticed that it was significantly harder to lift her feet up than normal. Perplexed, she looked down, noticing the pink hue of the water there. What had that Vaporeon spit at her? Nonetheless, she would not give up so easily. She lifted up her foot, the pink water stretching as it tried to keep her in place, but after a few seconds it snapped, releasing her foot. A few difficult steps later, she was out of the pink goop. However, even despite that, she still found it fairly difficult to take further steps. Looking down again, she discovered the cause: The bottom of her shoe had turned pink, stretchy, and sticky. It was no less sticky than the puddle, though in this case it looked just like bubblegum. Were her shoes somehow turning to gum?

She had no idea how this was happening, but she had a feeling that taking her shoes off would be a good idea. But unfortunately, when she tried slipping her foot out of her shoe, she found herself unable. The inside of the shoes remained quite thoroughly stuck to her feet. In fact, her feet seemed to be quickly getting more and more stuck. And, more alarmingly, it didn’t even feel like her feet were stuck to her shoes anymore. Rather, it felt like her feet and her shoes were one and the same. She could no longer feel the point where her feet ended and her shoes began. She tried wiggling her toes, but she couldn’t. In fact, it didn’t even feel like she had toes to wiggle anymore.

However, the feeling of having no toes did not last long. As her shoes transformed, they gradually lost their shape. Soon, they didn’t look much like shoes at all, but simply blobs of gum encasing her feet. But then came an even stranger development, as the ends of her gum shoes separated, forming into three toes at the end of each shoe. And when she tried wiggling her toes again, those three new toes were what she saw and felt wiggle, even if they were sticking to each-other a fair bit as they did so. It was at that point that she realized what was happening, as impossible as it seemed: Her shoes had melded into her, as her feet had transformed into gum feet. Or perhaps... gum paws, by the looks of it?

With some difficulty, she lifted up one of the paws, getting a closer look. It was definitely a paw, complete with a cute little claw at the end of each toe. But as she looked at the new paw, she noticed that the changed hadn’t stopped yet. The gummification was spreading up her ankles, now!

Indeed, it was quite alarming, but what could she do. Cry out for help? Run away? Even if someone heard her, what could they do, other than perhaps fall prey to the same strange transformation? And she could hardly run away from a transformation. After all, she’d already freed herself from the puddle that had caused it, yet her changes were still continuing, nearly up to her knees now.

But just as the changes overtook her knees, she noticed something: Was it her, or was she getting shorter? Indeed, she was getting smaller, slowly but surely! Both the transformed and non-transformed parts were shrinking in unison. But how small would she get by the end of it? And how was any of this happening? How was it even possible?

Soon, as the trash cans were nearly as tall as her eyes, the gum reached her waist. By this point, her now-gum legs had reshaped themselves, looking much more like a quadrupedal Pokémon’s legs than any human’s legs, gum or otherwise. Her jeans, of course, were no more, absorbed just as her shoes had been. And once her waist transformed, she was finding it difficult to keep her balance. For the sake of comfort, she allowed herself to go on all fours. Then, she felt something growing from above her hind.

Looking back, she saw something growing there, short and thin at first, but quickly growing longer and thicker. As it did so, the tail seemed to be developing something resembling one long fin along its length. And at the end developed what appeared to be the ending of a mermaid’s tail. Or perhaps... could it be... a Vaporeon’s tail?

It was! As improbable as it seemed, this looked and felt far too real to be a dream. Giving a new tail a quick, elegant wave, she realized that she was achieving a lifelong dream: Much as she’d always wanted to own a Vaporeon, even stronger was the desire to become a Vaporeon herself! Sure, she’d never have expected to become a Vaporeon made of gum, but she was prepared to take the good along with the bad.

Except... thinking on it further, could she really call this unexpected development bad? As the gummification spread up her waist and to her chest, the fins continued on from her tail, along her back. And the more of her that transformed, the more she noticed that the ordinary aches and pains that came with being a human, and likely with being a Pokémon, were no more. They were replaced with a feeling of all-encompassing softness and comfort. She also noticed that, as a consequence of no longer needing to wear clothing, she could feel the afternoon cool air much more clearly, which was quite soothing. And although her newfound stickiness hindered her movement, she had to admit that feeling her body stretch and compress so easily was a very novel feeling indeed.

With some difficulty, she turned herself around to look again at the pink puddle. Sure, it clearly was no ordinary water, but it would still show her reflection well enough as her transformation continued, so she could better observe it. Of course, the reflection would be quite pink, but so was she, so that was perfectly fine.

Next to change was her arms. Or rather, as she watched them become, her new forelegs. Then, her hands changed into cute little forepaws. She wiggled the toes on them, before lifting up a sticky forepaw, then touching it to her tail, feeling the her paw sticking to the soft and squishy surface. Even the stickiness, now, was growing on her. Inconvenient, perhaps, but it was definitely a pleasant sensation. Perhaps someday, she would be able to better control her stickiness, becoming non-sticky when she wanted. But for now, she was content to enjoy her adorable new body.

But of course, that body wasn’t done developing quite yet. She pulled her paw off her tail, watching the two stretch as she pulled before finally coming apart. Then, she set her paw back down and looked back at the puddle, just in time to watch a large frill form all around her neck. By this point, she was the exact size of a normal Vaporeon, and all that was left was for her head to transform.

And indeed, it did not take long. The first to change was the back and top of her head, her short hair quickly receding into her head and disappearing, replaced with a tall fin. Then, the transformation moved inward toward her face. Her eyes became much larger, wide and cute like a Vaporeon’s. Then, on each side of her head formed another fin, reshaped from her ears. Then finally, the last part of her head to change were her mouth and nose. She watched as the gum transformed them as well, pushing them out into a short muzzle, her nose changing from a human nose to a little cute gum Vaporeon nose. And with that, her transformation was complete.

She lifted up a paw and touched it to her cheek, rubbing her cute, squishy face. She was so adorable! But just as she was thinking that, another thought entered her mind: If she had the form of a Vaporeon, did she have the abilities too?

It was an exciting idea! She simply had to find out! But how? What should she start with? She’d always wondered how it felt to use Acid Armor, but that seemed like a pretty complex starting point. Perhaps she should start simpler, with a Water Gun.

Lowering her paw, she closed her eyes. She didn’t know exactly how Vaporeons did it, but perhaps if she just... let it happen naturally, it would come out? It was worth a shot. And so, she inhaled deeply. Immediately, this felt right. She let herself go through the attack naturally, and soon after inhaling, she exhaled some pink water.

Except, she didn’t. In fact, she’d made a critical mistake. Yes, she’d allowed herself to let her new form’s nature take over the attack, which was the right thing to do. But she’d also let her new form’s nature take over her new form itself. And that form had one property in particular that became more prominent now that she let it be so: its stickiness.

As a result, when she tried to open her mouth for the attack, it remained stuck shut. Even so, the water from the attack was still being formed and, with nowhere else to go, it went right back inward. Her eyes quickly opened wide, as instead of feeling her mouth open and water pour out, she felt the water being forced into her own belly, causing it to start expanding. She braced herself for pain, as she knew her belly was going to be flooded with far more water than it was ever meant to handle, but it did not come. Instead, she quickly discovered that it felt... pleasant?

Indeed, so much water flowing into a human’s belly would be painful, and very likely fatal. But she was no longer human, or even flesh-and-flood. So instead of the pain she’d expected, she instead felt a rush of pleasant sensations. One was the feeling of the water flowing in. It felt as if she was receiving a belly rub and massage, but this one was coming from the inside, massaging her whole belly at once. But also, while the feeling of her body stretching earlier was pleasant, this was far greater.

As she felt her belly stretching and growing, she couldn’t bring herself to be worried, for she was too busy enjoying the feelings of her belly growing larger and larger. Soon, her belly touched the cement below. Then, it pressed onto it, her taut belly pushing against it as it continued to grow, her paws no longer able to reach the cement at all. She nuzzled her growing belly, tail wagging as she rubbed her belly with her paws, as well as she could with such sticky paws.

By the end, when the water finally stopped, her belly was fully round. But even though the expansion had stopped, her taut belly still felt positively wonderful. She gave her belly another nuzzle, not worried at all about being rendered unable to walk. She could probably simply open her mouth and let the water out if she wanted to. But she had no interest in doing that. The water felt too wonderful in her belly. So wonderful, in fact, that she soon found herself falling asleep, as content as could be with her new form.
