When a miss casted spell causes Starlight to turn into a pool toy, Trixie is very amused when she finds her.

An alternate take on the original where Starlight accidentally casts the spell upon herself before she can do it to Twilight. Needless to say it rather en-lightening. Trixie finds it amusing that's for sure.

Poollight Glimmer

Starlight eagerly grinned, flipping through the new tome she’d found full of new spells for her to try. There were just many pages to choose from that it was hard to pick. Inside she had stumbled upon a section on transformations which had caught the unicorn’s eye. With Trixie coming back from her latest show, she wanted something special she could show to her best friend. Impressing Twilight would be a nice bonus on top of that.

Naturally, she was already well versed in how to turn some objects into others. But there were also many other ways to do it. It varied in the cast and material for the most part. She’d even recalled the story of when Twilight had turned her friends into Breezies. When her eyes caught the lines about inanimate transformations, she started paying full attention. Petrification was one of the more obvious ones. However, there were other things that a pony could supposedly become, like cloth. She chuckled as the mental image of Pinkie as a life-sized plush crossed her mind. “I’m sure she’d be up to try that,” Starlight said, scanning the page more before stopping. “Hmm, what’s this? Inflatable spells?” The use of the spell was made clear by a picture of a pool toy next to the writing.

As she stared, a smirk spread across her face as she thought of a prank she could pull on Twilight. The perfect summer weather outside would be a good lure. Although, she figured she should test it first just in case. Looking around the room, she spotted a box of Trixie’s props she’d agreed to store for her. “Oh, there should be something I can use in there!” Moving over to it, she opened the lid before rummaging through the assortment of items before tilting her head when she pulled out one in particular. “Huh.” Held in her hooves was a plush version of herself with its black beady eyes looking back at her. Even the cutie mark was stitched correctly. “Why does Trixie have a doll of me?” She muttered, blushing as she turned around and hoped not to think about it too much. “Yeah, this thing should do,” she added, her horn beginning to glow as she prepared the spell.

While she’d been searching for the prop, a small red ball ended up knocked out of the box and was now directly in Starlight’s path. With her horn still alight, the mare’s hoof came down upon the ball, sending her toppling forward, her head smacking the carpet. As her focus dropped, her horn discharged, sending the blast firing upwards, hitting her friendship mirror before bouncing off the ceiling and impacting her back, the force knocking her to her belly. A cold feeling ran down her horn and along her spine as she lay there in a daze. Her legs twitched, unable to gain control as a lightheaded sensation washed over her. She tried to get up, but her body didn’t seem to be listening at the moment as more tingling prickling ran along her legs and up her barrel. As the spell washed over her, her muzzle felt numb as her breathing slowed and soon started to sound like squeaks and huffs. The last thing to happen before control returned to her was her eyes pulling open unblinking and wide in a happy expression.

Wobbling slightly, Starlight rose to her hooves, hearing squeaking as she did. She immediately saw the first signs of what had happened as she saw her reflection. Smooth and playful eyes stared back at her with a wide grin fixed to her muzzle. In the middle of her painted grin sat a small valve. She found this was the source of her huffs and squeaks. The valve was similar to that of a rubber duck. “You have got to be kidding me,” Starlight thought, mentally blushing as she lifted her left foreleg to see the results of her mishap. The hoof was rounded on the bottom, seams holding her together. Each side of her leg had similar lines. “Oh dear,” she said, looking back into the mirror. Matching seams ran down her ears and a solid one that split her head in half. The rubbery unicorn sat down with a huff, jumping when she sat on her balloony tail. Moving it aside, she raised her forelegs to her muzzle and pressed into her cheeks. Her skin flexed and squashed as she did. The sensation filled her with an odd sense of joy. She giggled inside while letting out a few squeaks as she experimented. She could even smell rubber with each inhale and squeak she made.

It was a solid minute before Starlight realized what she’d been doing. She shook her head. “Gah, focus,” she said sheepishly, reaching down and feeling the seam along her barrel. While her touch was a bit muted, she could feel the air inside her shift and cool to room temperature around her. Turning her head, she took a glance at the rest of her body, watching her rubbery skin shine in the sunlight shining through the window. Reaching down to her hips, she rubbed them gently and giggled as she examined her figure. “Hehe, I think my hips are bigger.” She always did like looking at those salacious magazines with those mares in tight-fitting lingerie, showing off their lovely curves and ass. She always figured they’d used magic to have their figures so exaggerated but lovely to stare at either way. She wagged her rump, laughing inside as she gave her flank a slap watching it jiggle all bouncy. Taking a second to look at her right flank, she saw what she guessed was the inflation valve indented just above her cutie mark. “Hmm? Well, this isn’t so bad. Kind of strange, though probably should change back soon.”

Before she could finish her thought, the door to her room swung open, followed by a familiar blue pony’s proclamation. “The Great and Powerful Trixie has returned to hang with her best friend.” Trixie paused her performance shocked by seeing a big rubbery flank in her view. “Huh?”

Starlight squeaked, jumping in surprise as she turned around, blushing on the inside. She hadn’t thought Trixie would be back so soon. Squeak squeak huff!

“Why is there an animated pool toy of Starlight in here,” Trixie muttered, staring at the toy before her as it moved around.

Starlight rapidly shook her head, not wanting Trixie to get the wrong idea, as she gestured to the spellbook and back at herself before waving her hooves, attempting to mime out her situation.

Thankfully, Trixie, after a moment, seemed to understand. A smile slowly crept onto her face. “Starlight, is that you?” Putting a hoof to her muzzle, she began to snicker. “You turned yourself into a pool toy?” Her snickering soon turned into full-blown laughter as Starlight sank her face into her hooves in embarrassment. Moving over to her friend, she grabbed Starlight around her middle. “Always did say you needed to...lighten up!”

Without much effort, Starlight was tossed up into the air toward the high ceiling, swaying her hooves around in protest. Her huffs of air, an attempt to talk, were fruitless as she floated down harmlessly like a leaf. Landing slightly leaned to her left, the baloney unicorn was unable to stop herself from falling over onto her side, bouncing a little as she did. “Ugh, this is embarrassing, but why do I feel tingly?” Starlight thought, kicking her legs, trying to get up.

Trixie hoisted Starlight back onto her hooves, still giggling at what was before her. “You know, Starlight, with how you are right now, it would be a great time to go hang out at the lake out back,” she suggested, prodding at her friend's rubbery chest.

Every touch to her body by Trixie caused the odd, pleasant tingling to linger as Starlight shook her head. “No! No, not like this. No way,” she thought, making squeaking sounds as she protested. She started to regret ever doing this to herself in the first place.

“Oh, come on, have some fun,” Trixie declared, wrapping her hoof around Starlight's shoulder and pulling her in for a half hug. She made a face as she did, giving the toy another squeeze. “Hmm, something feels off,” she muttered. Pulling away, the magician rubbed her chin before pointing. “Ah, I know. You need more air.”

Starlight shook her head rapidly, feeling flustered at the idea. But now that Trixie had brought it up, she did feel a bit sagging in some spots. Momentarily distracted by the thought, she missed Trixie’s horn glowing as she summoned a red tire pump. When she felt a push on her flank, she jumped and turned to huff as Trixie pulled on the valve, readying to pop it open.

Trixie smiled back at her friend confidently. “Relax, Trixie is just trying to help,” she said with a chuckle.

Starlight tried to push Trixie, but her inflated form didn’t have much strength, to begin with, leaving her to watch as Trixie opened up the valve. She felt air rushing out of her for a moment, causing a shiver as the nozzle was securely attached. Letting out a few huffs in protest, she watched as Trixie lifted the plunger and pushed, forcing fresh air into her form. Another pleasant sensation washed over her. As she felt her body straighten out, the rubbery skin pushed outwards from the pressure. The next rush of air made her insides creek as they stretched, and her hips expanded further. With the third pump, Starlight began to feel a bit tight, finding it harder to flex her limbs. Straining to turn her head, she saw Trixie lift the plunger again. Her squeaks went unheard as more air flowed into her. Her head immediately snapped back into place, mentally moaning at the pressure pulling on her from all sides. It wasn’t impossible to move, but it was quite the struggle to do so without her air forcing her back to the default pose. “T-Trixie, stop! I’m s-so full!” Despite her huffing and squeaking, Trixie gave one last pump, filling Starlight's ears with creaking.

“Ah, there we go,” Trixie said, experimentally thumping her hoof against the firm flanks, hearing a thunk as she did. The magician patted her friend’s back, watching Starlight weakly wiggle her legs. “Now you’re properly inflated,” she teased. “Are you feeling okay?”

Starlight silently moaned, the smack having felt really good. Even as Trixie's hoof traced down her back, she found it rather nice to feel the constant pressure on her skin. Despite how full she was, she managed a slow nod. “S-so good.” Even as Trixie scooped her up, her thoughts felt fuzzy, with each touch or brush of air causing a delightful shiver. The toy would wobble from side to side on occasion.

Sliding Starlight over her back, Trixie moved to the door. “Come along, Poollight, time to play,” she teased.

Starlight groaned, wobbling side to side as Trixie walked. She soon felt the sunlight hit her rubber skin once they were outside. Given there wasn't much she could do, the toy pony just watched the scenery go by as Trixie made her way down the path towards the lake behind the castle. Given a moment of quiet, Starlight figured now would be as good a time as any to attempt to use magic. The only sign of her struggles was a few huffs from her valve as she tried. “Gah, come on! Not even a spark...shoot,” she thought, realizing she had to rely on somepony else to cast the counterspell. Till then, however, she’d just be a hunk of plastic.

As they approached the lake, Starlight heard some splashing and turned her head to see Gallus on the shore watching Silverstream shoot out of the water in her Seapony form, doing a flip in mid-air. The two students soon looked their way as Gallus waved. “Oh hello, uh...Trixie, right?”

Trixie put her hoof to her chest. “The Great and Powerful Trixie!” she declared, jostling the toy on her back.

Silverstream pointed at Starlight with a gasp. “Wow! Is that a pool toy of our school counselor?”

Trixie smirked, waving a hoof idly. “Oh, you could say that.”

Starlight, the entire time, hadn’t even flinched, being too startled to think of what to do as she turned her head just enough to watch Silverstream climb out of the water, changing back to her hippogriff form before approaching to look at the toy. Feeling it would be too embarrassing for others to find out right now, the unicorn stayed still for the moment. The air pressure inside her helped her do that regardless.

Silverstream booped the nose of the pool toy, listening as it let out a huff through the squeaker. “It looks just like her, only bigger.”

Trixie smiled, holding back her snicker. “Oh, yes, it does have a big bottom, doesn’t it? Perfect for the water,” she replied before trotting to the water's edge. Setting her cape on a nearby lawn chair, the magician began to wade into the water, placing Starlight in front of her before pushing it further outwards into the lake.

As soon as Starlight’s belly came in contact with the cool water, the pool toy shivered at the stark contrast between it and the hot sun above. The tingling felt rather pleasant, like a massage rippling through her skin. Every little wave that splashed against her resulted in her letting small huffs of air out of her mouth valve. “Mmm, why does this feel so relaxing?” She thought, even as she sank partly into the water when Trixie climbed onto her. Each touch caused a little tremble inside her form. She let out a loud huff as her friend soon positioned herself against her stiff neck while the hind legs lay draped over the hips.

Giving a firm pat to Starlight’s bouncy side, Trixie stretched and relaxed. “Ahh, wasn’t this a good idea, Starlight,” she teased. “And all you have to do is act as my floatation device.” With another giggle, she closed her eyes, enjoying the warmth of the sunlight.

The next half an hour went by quietly, as the two students from before had headed back to the school, leaving the two alone at the lake. Despite her locked gaze, a small bird’s nest was within her sight to watch as she floated there. At first, she’d been rather annoyed but had quickly relaxed as Trixie’s hoof slowly circled her side. After a while, Trixie spoke. “Mmm, I wonder what it’s like to be rubber,” she muttered, pressing her hoof against the plastic. Hearing a few squeaks in reply, she continued. “I guess Trixie will have to ask you once this is all over.”

Starlight felt soothed by the side massage, listening to every word Trixie muttered. It wasn’t a bad feeling now that she’d gotten used to this form. The constant pressure, squeezing, and creaking had all started to feel natural. It was good that the spell at least let her move around instead of being purely inanimate. When Trixie’s mutterings had stopped, Starlight figured it was a good time to get a little payback as she rocked the best she could in the water. Moments later, she heard Trixie let out a startled yelp as she fell with a splash.

Trixie shook her head, as she resurfaced, hearing a series of squeaks coming from Starlight, figuring that was her laughing. “Oh, haha. You airhead.” Trixie retaliated by smacking Starlight’s inflated flank, hearing the toy let out a loud squeak in surprise. Clambering back on, the magician did another playful spank before adjusting herself. Both paused for a moment before laughing in their own ways, and once it had died down, Trixie sighed. “Your transformation has made Trixie remember a strange dream that she had once.” Feeling Starlight turning her head curiously, she continued, “Well, Trixie was at this big kid’s party performing tricks and astounding magic as usual.” Trixie flaunted. “It turns out that Trixie was actually made of plush the entire time, and kids kept hugging me. It felt rather nice too.” Shifting around, Trixie soon turned herself over and laid her head against Starlight’s big head. “Do you think we might try that later?” She asked, sounding sheepish.

Starlight would have blinked if she could, listening to Trixie’s small tale. She thought it over as she bobbed in the water. Given that the book that had gotten her into trouble in the first place had the right spells to do what Trixie asked, she figured that turning her friend into an oversized plush might be kind of fun as payback. Nodding her head in reply, the two were surprised when they heard the flapping of wings approaching.

Trixie looked over at the sound, soon spotting Twilight flying overhead, hovering in front of them as she looked. “Trixie, have you seen Starlight?” the princess asked before noticing what Trixie was lounging on. “Wait, Trixie, did you change Starlight into a pool toy?!”

Trixie rolled her eyes before smirking. “No, Trixie did not. Starlight turned herself into one,” she replied, giggling a bit. “Isn’t that right, Poollight?”

Starlight would have blushed if she could have, as she slowly nodded, creaking filling her ears. She wasn’t sure what Twilight would say about her blunder but was surprised to hear her let out a small chuckle.

Hovering up to the front, Twilight booped her hoof right between Starlight’s eyes. “Well, I guess if you two are having fun, I can handle the budget meeting by myself,” she said, watching as the pool toy tilted its head.

Trixie kicked her leg against Starlight’s rump, hearing a satisfying squeak from the toy. “Don’t worry, princess, when Trixie is done playing, Trixie will help change her back. So far, she loves it.”

Twilight pokes at the toy one more time before smiling. “Alright, Trixie, you two have fun.” With that, the princess left, flying back towards the castle.

Once Twilight had left, it wasn’t long until the still silence resumed, with gentle bird song filling the air. Trixie got comfy once again, falling asleep within moments, her one foreleg dangling over the side. Not wanting to wake her friend, Starlight remained still and let the silence soothe her into a zen-like state. After thinking over a few spells in her head, the pool toy pony relaxed, losing track of time, as she let the feeling of the warm air and cool water massage her.

Trixie woke up after an hour, yawning and stretching out, nearly falling off her friend. Patting the toy, she smiled. “Well, that was nice.” Sliding off into the water, the magician pushed the toy to the shore. Climbing out, she picked up the toy out of the water in her magic before heading back indoors. Hearing a few squeaks from her rubbery friend once in Starlight’s room, Trixie nodded. “Yes, yes, Trixie will change you back.” Walking inside, she set the toy on the floor and patted the flank before rubbing her chin, having a small idea. “What if Trixie deflated you and folded you up?” Trixie asked, seeing Starlight tilt her head. “Well, Trixie is curious what it feels like, and you can tell me once Trixie inflates you and turns you back.” Nudging into Starlight’s side, she beamed, waiting for a reply.

Starlight was worried at first, unsure how that would feel. After all, it would leave her utterly helpless at that point. However, she did trust Trixie enough to know she wouldn’t mess with her too much. Starlight let out a squeak, nodding before feeling Trixie pop open the valve. The moment that air started to rush out of her, Starlight’s whole body began to tingle. Wrinkles started to show as her pressure dropped, feeling a wave of dizziness come over her. She shifted her looser hooves, every little shift causing more air to puff out.

Before she got used to the feeling, Trixie laid Starlight onto her side before pressing her hooves down, causing a rush of escaping air. Starlight’s disorientation grew, feeling dizzy as if she’d been spun around a few times. Her hooves began to become less responsive with each bit of air that left her, and she found she didn't have enough left to make squeaking sounds. Her mute and unwavering smiley face could do nothing as she got a close and personal look at the bottom of Trixie’s hooves as they pressed down upon her muzzle. The unicorn had expected to feel cold as her halves touched, but the empty feeling surprisingly felt like falling half asleep. She was only half aware as Trixie proceeded to fold her up, the attempt taking a few times before she got each limb creased and tail tucked in just the right way to leave Starlight’s face on top with those big eyes staring back at her.

“It’s a shame that you’re needed at the school, or else Trixie would happily take you to the beach,” Trixie teased as she held up a camera that had been sitting in Starlight’s room and pointed it at the toy. “Say cheese!” After taking the photo, she got to work undoing her nice folding job, laying Starlight out to be refilled.

Starlight was relieved and surprised that when the air started to be pumped back into her, she felt a sort of euphoria, with a pleasant sense of satisfaction mixed on top. When her form was back to being fully inflated, she watched as Trixie skimmed the spellbook for the needed spell, lighting up her horn. The unicorn’s scrunched-up face was kind of cute to watch as Starlight felt the magic wash over her. A prickly sensation washed down from her neck, moving across her form as her fur returned, making her shudder as movement returned to her. As her head returned to normal, she shook her head and rubbed her cheeks. “Ugh, it feels like I’ve been smiling for hours.”

“That’s because you were you goof,” Trixie jested, playfully ruffling Starlight’s mane.

Starlight brushed away her friend’s hoof, blushing slightly. “Uh hehe, right.” Making a quick glance at her hindquarters, she looked back at Trixie. “Thanks for the help. I guess being like that wasn’t so bad.”

“Trixie told you she just wanted to have some fun. You can tell Trixie about it during supper. Trixie is starving,” Trixie said, smirking when Starlight’s tummy rumbled as if in reply to the statement.

The two laughed, entering the hallway and heading towards the castle’s kitchen. Starlight smiled back, remembering the conversation from earlier. “And maybe after that, I can try and make you a plush, just like you asked. The Great and Huggable Trixie.”

Trixie just blushed in reply, pulling her hat down a bit in embarrassment. It sure had been one weird day, but Starlight had to admit, it had been a great day off at least.
