The Infinity Collar
By Balloondra

“Anything?”

“Fine, nearly anything. It can’t go making you into a planet or a god or anything like that. But you know what kind of ‘anything’ I mean.”

Erablier, a fuzzy, blue fur with a lithe body, long ears, long hair, and a bushy foxlike tail, frowned again at the collar in his thick handpaws, while his reflection in a nearby full-body mirror did the same. The collar was rubbery and puffy to the touch. It was filled with air, much like Stera, the snake who stood in front of him as the two of them in the abandoned warehouse where they had decided to meet.

She was a cobra, at least in appearance, and she was the one who brought collar and mirror both. Her tan “scales”, if you could call them that, were merely painted on her hollow, vinyl body, and a thick, slightly puffy inflatable hood framed her friendly yet slightly sinister face. Her figure was curvaceous and clothed in a long robe, and behind her, a tail with a valve on its side waved back and forth. Era hoped it was just her species and those vertical pupils and long, hopefully inflatable fangs that made her look like she had something unpleasant up her sleeve, especially with what she was promising.

Era eyed the collar again, suspiciously. “And all I have to do… is put it on.”

“And tap the gem in the tag, yes. Stars, boy, if I was going to hurt you with my magic I’d have done it long before you got that collar! Just put it on! I’m trying to help you here! Grant your wish! Go on, now!”

Now the cobra was really starting to look mad. Frightened, Era pulled the collar over his head and around his neck. It was a snug fit, but not uncomfortable.

“Hello, wearer,” a voice said inside Era’s head. He started in fright and glanced at Stera, who only smirked with pride. “Please tap the jewel on me and tell me what you wish to become. I shall make you into that.”

The collar itself was talking? Era’s eyes widened as he tried to glance down at it. Even so, he found all of this rather hard to believe. Yes, he had met with the inflatable cobra at her request to grant a wish of his, but that was just out of curiosity. And now she was promising a collar with nearly limitless transformation abilities? Right. There was probably just a sound chip hidden in it that was speaking to him.

He put a fluffy finger on the jewel. “Make me a girl,” he said dryly, just to prove Stera wrong.

Then a jolt of energy surged through his body, shocking him fully awake and alert. It felt like a sharp tingling all over, but it was especially intense around his shoulders, torso, and hips. Then, to his amazement, he began to change. His shoulders slimmed down while his hips widened, and, based on how it felt between his legs, he was now a she. Her face flushed as a pair of breasts grew on her once flat chest and her rear end thickened to match. Glancing up at Stera, she noticed she was a little shorter now, too.

She didn’t think the cobra could grin any wider. “How—” Era began to say before yelping. Her voice was an octave higher at least! “How did you do this?” she asked.

Stera shrugged her shoulders, her expression becoming nonchalant. “Magic. The details aren’t important; you wouldn’t understand them anyway.” Then she smiled a little and walked past the new girl, her long, soft tail curling around Era before pulling away as Stera walked towards the enormously wide entrance to the building. “You have fun now. Just try not to forget what you used to be when you want to change back. Though, speaking from personal experience, you wouldn’t be the first!”

On that note, the living toy turned a corner and left.

Era hardly noticed, too focused on looking over herself in the mirror and grinning madly at the sight of it. She really was a girl now! Truth be told, it was something she had wanted for so long now, if only just to try it out. Her heart was racing. A girl wasn’t the only thing she wanted to become, so…

She thought about that soft, inflatable tail that had brushed past her. Could she… could she have something like that herself? Touching the gem on her collar again, she felt the magic within hum to life.

“Another form so soon?” the collar’s pleasant voice asked.

“Make me a pooltoy, please,” she asked, imagining the form in her head. Similar to how she was already— definitely female, she wasn’t done with that yet— a little taller, a little more bulky and puffy overall, smooth and glossy, and… well, she had always liked that style of inflatable with a wide grin simply painted on the muzzle.

Interestingly, only after she finished her imagining was she jolted with more energy. This time, the tingling feeling was intense all over, from ears to paws to tail. She winced at first from the intensity, then opened her eyes wide to watch the changes firsthand. Her fur was already starting to lie down flat; it seemed to congeal as it smoothed and softened into taut, shiny vinyl, consuming her clothes along the way. Hopefully she’d get them back when she turned back to normal. A funny feeling in her belly— sort of like butterflies— quickly became a funny feeling all over, accompanied by a sense of growing weightlessness. She was hollowing out!

A gentle hissing filled her ears; she could tell it came from within her. True to her wish, she was swelling up in addition to turning hollow, and already she was starting to put on a sort of puffy bulk all over. Fingers and paws thickened, becoming cuter, but less dextrous. Her form filled out, giving her belly a nice, full curve, like she had swallowed a beach ball, while her already curvy figure became more buxom still. The feeling of those parts of her stretching and growing— especially in her chest— was wonderful in a way she would have been shy to describe.

Suddenly, her eyes burned, and she winced again, snapping them shut. When she opened them again, though, something seemed… different. A glance in the mirror confirmed it— her eyes were just painted on now! She tried to gasp at the sight, but couldn’t; somewhere along the way, her muzzle had become one indivisible shape, just like a toy’s, complete with the wide, silly grin she had imagined for herself.

Her tail squeaked more and more loudly as it transformed, and a small pinching feeling on its side marked where the vinyl had twisted itself into a valve to match Stera’s. Curiously feeling it, she found it was more sensitive than she expected, and her face flushed— which in this form, looked as though her cheeks had been spray painted red.

She felt over herself with thick handpaws, delighting in the feeling and sound of her body squishing and squeaking softly at the touch. The friction made her whole body vibrate, which really hit home that she was just a hollow toy filled with air! Delighted, she began posing for herself, enjoying her new rubbery flexibility.

Yet her mind still raced with ideas. She could become nearly anything she wanted! Why hold herself to her own species? She tapped her collar tag again and—

...She couldn’t speak in this form. She almost began to panic, but then remembered that she had become precisely what she imagined, so hopefully…

She tapped the jewel again, this time imagining an inflatable dragon girl with a figure very similar to this favored one, but a few feet taller, with wide, puffy wings and a long tail with soft inflatable ridges down the back. She wanted to be green with a yellow belly, she thought.

She would have relaxed if the transforming energy didn’t shock her instead. Thankfully, her body flooded with energy as her rubbery “pelt” transitioned from steely blue to vibrant green and yellow. This time, her ballooned belly and assets remained unaffected except to grow with the rest of her. Instead, the changes mostly came in her paws as they shifted from relatively bulky mammalian toes to the more slender, clawed hands and feet of a dragon. A quick tap of the paw against the ground confirmed that her new claws were as rubbery and harmless as the rest of her.

Her tail lengthened as it slimmed down to a tapering dragon’s tail, but she found it delightfully nimble, and amused herself by curling and twisting it around herself.

Meanwhile, her head was rapidly changing shape. Her floppy ears were replaced with white draconic horns that angled backwards behind her. Her stout muzzle quickly elongated into something reptilian, and while it remained a simple shape with that grin painted on, she was delighted to see in the mirror that a couple of “fangs” were visible in the toothy print now.

For a moment, she thought the transformation was done there, but a tingling and pressure in her back preceded two nubs swelling out near her shoulder blades, elongating and zig-zagging in the air until they seemed to unfurl into huge, bat-like wings. A glance in the mirror confirmed that they were more than wide enough to cloak her entire figure. She waved them experimentally, fanning up some dust, but didn’t quite feel confident in trying to fly. Right now, she just wanted to admire her glossy figure!

This collar was powerful! Without so much as a word from Era, it quickly and effortlessly transformed her into precisely the form she had imagined— in more detail, too! She really wanted to test its limits now. So once more touched her collar’s jewel and did her best to visualize an inflatable spider girl this time, with a zig-zagging smile and puffy fangs to accompany a few extra limbs and a huge, puffy abdomen, one that was like a pooltoy in and of itself. She wanted her figure a little shorter, but otherwise the same— she liked her curve as is.

Her body tingled again, her pelt transitioning smoothly from vibrant green and yellow to a glossy midnight black. As she had hoped, the tingling feeling more or less ignored her belly and assets beyond that, except to shrink her to something a little more petite. Instead, her paws became two-toed, and behind her, her tail began swelling up, surprisingly remaining the same length as it rounded out into a huge, puffy abdomen.

Her draconic muzzle retreated back into her visage as six smaller eyes blinked open around her original two. Surprisingly, her vision didn’t seem too changed by them. Looking in the mirror, though, she smiled back at the spiky smirk in the mirror— though, considering it was painted on, she didn’t have much of a choice.

She happily poked at her new fangs, too, ones that puffed out at the corners of her mouth as her abdomen finished blowing up behind her. With a bit of maneuvering, she managed to sit atop it, enjoying its beach ball-like bouncy softness.

But as she did, feeling the tail-like thing squish and puff out beneath her, a thought occurred to her. She could become things like girls and toys and spiders, sure, but could she also become something like, say… a princess? It was a little silly, she knew, but at the same time, she loved the thought and just had to try it out!

So, touching her collar again, she indicated to the magical thing that she wanted to stay how she was, but “transform”, so to speak, into a princess.

Her collar, to her slight surprise, obliged. But rather than tingling energy surging through her, she was nearly blinded by a flash of light that enveloped her whole body! A low, long creaking sound, like rubber against rubber, filled the air, and as she brought her hands down, she flinched at feeling something atop her. Glancing in the mirror, she could see in the fading light… a long, elegant dress!

Well, “elegant” might be a little too far. It was almost like a cartoon of one— a thick, puffy, inflatable cartoon. Hot pink with decals of glittering sequins and real though air-filled ribbons delicately arranged around a wide, bell-shaped skirt and the form-hugging figure above. The sleeves were flared, giving the inflatable clothing some pleasant bulk. And finally, atop her head, was a glossy, glittering, inflatable silver tiara, complete with a shiny red “jewel” in the center.

She noticed that both of them seem attached to her, which was fitting for a toy princess, she supposed. Looking in the mirror, though, she couldn’t help but feel a little more regal, too. An effect of the collar or the getup? She couldn’t say.

Yet her flighty mind, intoxicated with all the transformation, wasn’t yet settled. She tapped the magic jewel once more and made her silent wish: to be a giant, puffy, round, spider princess balloon! She could see herself so clearly, blown up to near immobility, delightfully stretched and bloated and round, and yet her dress inexplicably fit, having apparently grown with her…!

Her collar obliged, surging her and her dress full of that energy to change. She quickly began to swell, her body going from curvy to pudgy to huge in mere moments. Little by little her limbs were forced apart by the growth, yet she remained fully clothed by her regal dress as if she had always been that size.

Her body began rounding out, slowly subsuming her bloated assets into one big ball, like a pink balloon that inexplicably had a spider’s head and limbs. But the more she stretched, the more her plump limbs sunk into her growing sphere of a body until it became difficult to remain upright. Her abdomen fared far better, but it still became hugely swollen to complement her balloon-like figure.

The more she grew, though, the tighter and tighter her collar became around her. If she wasn’t a toy, she’d have been struggling to breath as her swelling body demanded more and more room that the rubber collar just couldn’t provide. She felt it strain and creak against her until… snap! It ripped open, flinging off her neck…

But not before overloading her with one last jolt of energy.

Her inflation drastically accelerated. In a single moment she blew past her desired size, the hissing in her ears louder than ever as she blew up like a party balloon attached to a firehose. Mere seconds later, her body, now little more than a shiny pink ball thirty feet across with indents to mark where something spidery once was, began to creak loudly; she could feel her elastic form straining much like the poor collar had. But there was nothing she could do— even if she could still press the jewel, it was far below on the ground, and the spider girl’s world was nothing but shiny, pink, hissing pressure now. She still tried to hold herself together, as if she could simply will herself to resist the endless flow of air, the mounting pressure, her body being stretched to its limits…!

But, with a sound like thunder, she exploded, raining down black and pink confetti to the floor of the old warehouse.

…

Sometime later, she awoke. Was it all just a dream? She yawned and rolled over— only to find herself quite incapable of rolling. Her eyes snapped open, revealing a wide, curving, embroidered pink expanse before her. She was still an inflatable spider princess! And… she was still a giant balloon! Awkwardly, she felt for her neck, but she couldn’t feel the collar. She gulped. She was stuck this way.

In a panic, she leveraged her abdomen and some wobbling motions to push herself back onto her feet, and thankfully found that she could get around with an awkward half-walking, half-bouncing motion. She found the collar easily enough, but tapping it with her foot, she could tell the magic had been broken along with the collar. Nervous, she frantically thought of a way she could fix this.

...The cobra lady! Stera could help her get back to normal, she was sure of it. Even if she had to make a new collar, which… Era was sure she could. She had to. She didn’t want to be stuck like this!

But where had the cobra even gone? The bloated spider girl kicked up the collar carefully with a foot to let it rest atop her toes. She tried to remember if Stera had mentioned anything… No, not that Era could remember. Era would just have to find her the hard way. She began bouncing towards the entrance, which was thankfully wide enough to let her through. She realized other doors… wouldn’t be so accommodating.

She sighed. The balloon girl would need to find that magical cobra the very hard way.
