"Oh, I see what you mean..."

"Yes. I was hoping you might have some insight..."

Twilight Sparkle and Fluttershy looked at Angel the Bunny with worried glances. Angel had never looked better, Twilight supposed, but then he didn't quite look like himself, either. For one, he was much bigger, more than twice the size she'd last spied the white rabbit. His proportions weren't the same as they had been either, and his paws, ears, and body all looked much bigger in relation to his head. He had his front legs crossed over his chest, able to let them stand in for the arms of a biped in a look of wary annoyance. That was standard behavior for the sometimes unsociable rabbit, but as Twilight looked closer, she could see that the erstwhile arms appeared to be bulging with... muscle?

Enduring the stares for long enough, Angel quipped something in irate gibberish. Fluttershy frowned at him, turning to Twilight and translating, "He, uhm, he says he's been working out." She was her usual overpolite pegasus self, but even that couldn't hide the incredulity at the edge of it.

Twilight wasn't able to hide it, quirking an eyebrow, "Doing WHAT?"

Angel chittered, miming his arms lifting something heavy overhead his head. Fluttershy provided the meaning, "Lifting rocks."

"Lifting... rocks..." Twilight added, each word mired in suspicion as she judged the now hulking hare.
Angel stomped one of his feet and continued to gesticulate and chatter, leaving a long pause at the end for Fluttershy's benefit. "He, uhm, he says he's been lifting rocks at the Castle of the Sisters. There's lots of rocks of all sizes there just lying around," the yellow mare provided.

Angel held his front paws together an gradually brought them apart, then again implying he was lifting something heavy. Then he flexed, and kissed each of his "arms" in what passed for a bunny bicep. He nodded at Fluttershy and began hopping away.

Twilight's eyes shifted slowly back to Fluttershy, awaiting explanation, while her expression couldn't hide both the disbelief and confusion.

Fluttershy continued, "He started small and work his way up. And now he has.. uhm... massive gains."

Twilight furrowed her brow, "And... you believe him...?"

Fluttershy looked immediately conflicted, unwilling to cast around an accusation like lying on one of her friends. "He... he has been trying to impress a doe that comes by the cottage. He's competitive... and stubborn. So I can believe he was trying to, uhm, improve himself..."

The downy pegasus had trouble with the next bit, and surveyed the room to be sure that Angel had indeed vacated. "But his... massive gains... seem... too massive..." she struggled to say.

Twilight laughed quietly, "You think?"

Fluttershy shrunk in on herself, letting her pink mane fall across and hide her face. Despite the considerable height advantage the leggy pegasus had on the little unicorn, she looked small.

Twilight shook her head and reached out a tender hoof to reassure her friend, "Sorry. I didn't mean it like that. It does seem unlikely for him to change so much. Let's take him at his word..."

The Everfree seemed less frightening than it used to. By all accounts, Nightmare Moon had been wholly contained within the moon for a thousand years. But having vanquished Luna's darkness here, it was as though a bit of the oppressive thickness had been lifted from the forest, the Castle of the Sisters in particular. It still held plenty of danger for any careless pony to plod into, but it was no longer the foreboding presence it had once been.

Twilight Sparkle and Fluttershy arrived in the early afternoon. The forest was lively and bright, and Celestia's gentle sunlight streamed down on the old stonework and columns of the Castle of the Sisters. It felt so much different than it did the night Luna returned as Nightmare Moon. Birds sang without care, and the castle seemed home to a number of other small critters who'd taken advantage of the shelter. Fluttershy didn't even seem nervous, though ever her unsure and cautious self.

It was actually Fluttershy who broke the silence first, and Twilight turned, believing the words were meant for her. Instead, the pegasus was conversing with one of the birds. Twilight had to remind herself that it was one of the things Fluttershy could do, whereas the unicorn was prepared to charge blindly into the castle to see what she could find without guidance.

The unicorn waited patiently while the pegasus finished her conversation. The bird resumed its earlier tweeting song as it took flight and Fluttershy then explained, "Mr. Finch says that Angel Bunny's been crawling into one of the rock piles... over here..." She pointed with a wing, and then naturally let Twilight resume the lead.
It looked like many of the other piles of crumbling masonry that had left the main hall of the castle open to the sky, but a more careful inspection and a few large chunks of masonry magically moved from the way revealed a staircase leading downwards. A damp, rotten carpet that may once have been red clung to the stairs, and the air freed from below seemed just as musty.

Twilight grimaced at the scent, and felt Fluttershy nervously shuffle close to her. "I'm sure it's fine," she assured her companion. "After all, Angel wasn't afraid of this place."

She made her way down, more careful of her balance on the old stone steps than wary of any threats. She conjured a small light atop her horn as she left the sunlight above. Fluttershy followed, her wings seemingly torn between flaring to keep her upright or glued to her trunk in fear. The carpet dissolved away into nothing as the pair descended several spirals of staircase, the bricks becoming more even the lower they went.

At the very bottom, a wooden door half off its rusted hinges hung awkwardly to one side, affording little privacy to the room beyond aside from the tight squeeze through. Navigating into the space, Twilight couldn't immediately define what kind of room it was. The ceiling here was largely intact, but there was rubble and detritus nonetheless. Debris that might have been a table took up the center of the room, with wooden planks that could have been shelving lay near the outer walls, and whatever contents they held spilled along the ground. Broken glass. A bronze candlestick. A soggy leather cover was all that was left of a book, she imagined, flinching at the idea. A far wall had a musty pile of damp fabrics, moth eaten and moldy, reduced to just a few shreds of barely recognizable scraps.

Recessed into its own little alcove, Twilight could see something shimmer in the light from her spell. It looked out of place compared to the dusty wreckage around them. As she neared, it shown purple, then gold, somehow pristine among the ruin around them. Even without further inspection, the unicorn knew it was enchanted. Nothing but a magical object could withstand the devastation of age and neglect that had eroded the rest of the castle and still shine so brightly. A golden frame, large enough for two ponies to walk through, was inlaid with bas-relief depictions of flowers, trees, and various faceless equine forms. Inside was a pair of velvet or silk curtains colored a royal purple, with gold-braid on the bottom fringe. With the dust or fine rocky debris that had settled on every surface, it looked like it had only been kept in deep storage back in Canterlot Castle, not left to the elements for a millennium. The only thing truly out of place was the bottom right corner, where somepony, or more than likely a certain rabbit, had folded a curtain back and secured it with a rock. As she lowered her head to investigate, she spied what the curtains had been hiding: her reflection. It was a mirror. A magic mirror. The wheels began to turn in Twilight's head.

Twilight turned to call for Fluttershy, beginning with "I think I've found-" but stopped when she saw that the tall yellow pony had never wandered far, looming silently over the small unicorn while simultaneously trying to hide behind her. "I might have an idea, if this is what I think it is..." she began again. She bid her light spell aloft, growing brighter and bathing the entirety of the room in an even glow, to give the pair a better look. With a twinkling of telekinesis, she parted the curtains and exposed the full surface of the mirror. She was not at all prepared for what she saw.

The image that stared back at Twilight wasn't quite her reflection. Indeed, it was a reflection of a familiar purple unicorn, but it was not the same one that would greet her in any regular mirror. Much to Twilight's mutual surprise, embarrassment, and fascination, this reflection was pregnant.

In Twilight's mirror image, her short, plump pony frame was ponderously swollen on either side of her trunk, a massive arc of fertile swell extending towards the ground below. Far too large to be carrying a single foal, Twilight knew, the mare in the reflection looked quite overripe and uncomfortable with the exaggerated size. She took an experimental step forward and watched her reflection mimic it, Not perfectly, for the reflection wasn't a perfect match, but it was more or less accurate. Her studious eyes were quick to notice other slight differences aside from the advanced pregnancy and uncertain stance of her counterpart. She also recognized a certain flush to the cheeks, bright but tired eyes, and a thicker, longer mane and tail on the reflection, reminding her vaguely of the length of.... Fluttershy.

No bucking way...

Drawn away from her own visage, Twilight looked to Fluttershy's reflection. Her breath caught in her throat as she processed the image. Fluttershy's mirrored self was every bit as pregnant as Twilight's. The taller, thinner pegasus had a much different shape to her gravid stomach, pushing out less at the sides and bottom, with more room between her front and back legs to accommodate the size of her belly, but there was still little doubt that it was just as encumbering. Fluttershy's reflection stood awkwardly behind Twilight's, as if the legs didn't know quite how to distribute the weight they were carrying, while the wings folded higher atop the swollen expanse that was taking up their usual perch at the sides.

Twilight had ample time to collect her thoughts, as Fluttershy seemed just as perplexed and, perhaps, mortified by what she was seeing. It could be, the mage theorized, that the mirror was showing the idealized self... or was supposed to.

While Twilight greatly enjoyed the picture of herself heavily pregnant staring back, she wasn't sure that was her unbidden idea of her idealized self. It could also, she thought, reflect deep hidden desires, and that seemed perfectly in line with what she was seeing. She couldn't help but give herself, and Fluttershy, another appreciative glance, the two abundantly pregnant mares looking so innocently confused. She'd need more information before she could make an accurate assessment, and, as yet, she didn't know what it was Fluttershy might be seeing.

"Uh... Fluttershy... are you seeing... what are you seeing?" Twilight finally said, looking at Fluttershy's reflection rather than the pony herself.

Fluttershy's turquoise eyes were similarly glued to the artifact, and she took long seconds to form a response, "Uhm.... why are we... pregnant?"

Okay, Twilight thought. They must be seeing the same image. She began moving backward, past Fluttershy. She watched her reflection pass clumsily by the mirror pegasus's oversized belly. If it was reflecting her own inner desires, it might be related to proximity. Leaving Fluttershy closer could cause it to reflect a different fantasy. Both ponies' gazes still locked on the mirror, it failed to change to a new scene.

Twilight was beginning to worry she'd have to spill her entire fetish list to Fluttershy, and on the one hoof it was Fluttershy and she was going to at least pretend to be understanding, and on the other hoof it was Fluttershy and she was going to be terribly embarrassed to talk about such a thing. Her mind cast about, trying to find plausible, and less salacious, explanations.

"Well.... I think this mirror is enchanted to reflect inner desires," she started to say, suppressing the emotion in her voice. "But... it might not be working entirely correctly. The magic might have degraded from being down here for so long, if it ever worked to begin with..."

Fluttershy, or rather the reflection Twilight was staring at, looked at the unicorn expectantly. She knew the most faithful student too well, expecting a lecture.

Twilight continued haltingly, "I... have always wanted to be... a mother..."

Completely true.

"I've practically raised Spike, even with help, and.... it's been very rewarding... though not without its share of trouble."

100% factual.

"And I've... always wanted.. to have my own foals... a big family..."

Totally accurate.

"The mirror might be... making its best guess as to what that looks like..."

A wild guess, a fib, with a grain of truth...

Twilight was blushing heavily, her reflected rotund doppelganger following along, as she laid bare that little part of herself, the least embarrassing tip of the iceberg. Her eyes had wandered to far corners as she spoke, and when they found their way back to Fluttershy, the actual Fluttershy, she saw the pegasus had a little blush of her own. "Sorry... it's a little embarrassing to say out loud..."

The mirror momentarily forgotten, Fluttershy looked at Twilight and shook her head, "No, no. I understand. That's really very sweet. I, uhm, I also want to be a mother someday..."

Twilight relaxed, feeling a knot in her stomach loosen that she hadn't even realized had been there. A soft breeze briefly disturbed her hair, and her gaze found its way back to the mirror.

"Uhm.... w-why are we... pregnant!?" Fluttershy repeated out of the blue, a sudden pique of alarm in her tone.

Twilight hadn't noticed until she leaned slightly in Fluttershy's direction to respond, and then an unfamiliar weight took her farther than she intended to go. "Ah!" she squeaked, taking stock of her situation and realizing that the reflection in the mirror was no longer inaccurate. The pregnant pair of ponies in the mirror had been translated to the real world. The unicorn kept squeaking out half-formed questions of disbelief, trying to turn around on herself to get a better look at her changed form.

The unicorn was pregnant. Extremely pregnant, just like her counterpart in the mirror. Her heavy, tight stomach swayed with her motion, throwing off her entire center of mass. Soreness was creeping into her extremities as they shouldered the burden, She could feel the pressure her body was under. She could feel her womb strain and even her teats grown swollen. She had, after all, played with such notions before, but she hadn't been expecting it. Having it suddenly thrown onto her was like having all of her secrets exposed.

Fluttershy stood stock still, strangely much calmer than Twilight, but still wearing a nervous expression on her demure features. The yellow pony stood a good head taller than Twilight, a lean, leggy mare, now possessing her own pregnant-looking stomach. She seemed no less than Twilight's size, but she seemed to distribute it far better with her long body and legs.

The unicorn quickly tired herself out trying to escape her own body to get a better perspective, hefting around the considerable new weight. She inevitably bumped into Fluttershy as she stumbled over her own hooves. Neither pony fell, fortunately, and it seemed up to the pegasus to steady everyone, inside and out. "Calm... calm down, Twilight." she said softly, extending a steady hoof to hold against Twilight's shoulder. She listed forward, and had to correct herself, as she resisted the unfamiliar gravity. "You can figure this out..." she stated simply.

Twilight sucked in a ragged breath and nodded. "Right... right... sorry... I.... this is a magic mirror. A powerful one..."

Fluttershy would often be the first one to panic, but she always seemed to hold it together when she was the only one left able to do so. With that steadying presence, Twilight could organize her thoughts. The unicorn continued to speak out loud, not ignoring Fluttershy, but letting just her train of thought run out loud. "It's probably not meant to do... this! It's probably supposed to show you what you want... maybe even give you what you want... It probably gave Angel his... massive gains."

The magician began to pace. Not the wild spinning of before, but slow, thinker's steps, her mind now outracing the added strains of her body. "But it's so old... if it ever worked right it could have degraded and corrupted the spell matrix... it might be attuned to Angel... and if he was thinking about a girl, he might have had something in mind..."

Unmoving, Fluttershy nodded almost imperceptibly, whispering "That's... that's probably true..."

Twilight laughed nervously, quipping, "And you know how rabbits are?"

"Mhmmm..." came Fluttershy's reply through closed lips.

Twilight, ever the master of picking up social cues, finally realized that Fluttershy wasn't just steady, she was... stiff. The pegasus's long legs practically shivered in the attempt to keep her from moving. The one hoof she'd briefly extended had been a wooden motion, and it quickly receded as Twilight had gone on her tirade. The unicorn trotted closer, and mindful of her voice, she asked quietly, "Fluttershy? Are you all right? Are you in pain?"

Fluttershy took her time answering, seeming to redouble her efforts at staying still. "I... I'm afraid if I move I'm going to pop.."

Twilight snorted, emitting more inappropriate laughter. "You'll be fine. I'm fine! We're fine! We're all fine! I just need to figure this out!" She began to turn back to the mirror, but thinking better of it than to ignore Fluttershy just then. She gathered her nerves and continued, "You're not going to pop. Just relax."

Fluttershy didn't immediately follow the directions, but became a little more animated in her face, "B-but... I'm.. we're so big... aren't we.. p-pregnant...?" Her earlier calm was starting to crack now that she had Twilight back in the lead.

Twilight shook her head, "No... no.... this is a powerful illusion, or enchantment, or curse..." She paused, only to shake her head again, "That's not important... Creating new life unbidden is a terribly powerful magic. It's not something you can do just by looking in a mirror. We'd need a much more powerful ritual..." she paused again, swearing at herself to keep focused, "We're not suddenly going to be parents... this mirror is powerful, but only enough for a very convincing facsimile..."

"Oh..." Fluttershy answered, her emotion unreadable. The pegasus did seem to loosen, taking a slow breath that showed all along the newly minted swell of her middle.

"A-are you okay?" Twilight tried to confirm, unable to sense Fluttershy's mood more naturally but guessing she still held on to some tension.

Fluttershy's head lowered and shifted, her eyes searching for someplace to hide, "My boobs hurt..."

Twilight grew warm and bothered, giggling, "Mine, too..." she assured, rocking her head from side to side lightheartedly, forcing her own eyes to go anywhere but to where they might gander at Fluttershy's breasts. Blessing or curse, though, the pegasus's massive stomach was blocking all views from the current vantage.

After a long, awkward silence, Twilight felt her inner academic demanding she inform Fluttershy further, "It's... like I said... a powerful illusion. I can't guess what this mirror was used for, or if it was even supposed to do something like this, but I won't be able to figure that out without more materials to work with..."

Without looking, she used her telekinesis to pull the violet curtain back across the mirror's surface, and the light spell twirled from the entire room and back to the unicorn's horn. She added, "For now, let's get out of here. I'll try to dispel this once we're clear of the mirror. I don't want to risk dispelling the effects so close to what may be a broken artifact. It may react badly if the spell matrix is degraded."

Fluttershy nodded along, clearly out of her depth when it came to magic.

Twilight began picking her way through the rubble of the rest of the room, confident in her steps, if not her balance. The little problems started to crop up immediately, as her increased size caught on objects strewn about. She poked her expanded side with a broken table leg her former girth cleared without issue. She yelped in surprise, almost tripping as she scrambled to catch herself. She was much heavier, and her belly hung low enough that it brushed against rocks on the floor that she wouldn't have even noticed before, adding considerable difficulty to finding good footing. But looking back to check on Fluttershy left her with a little jealous pang. The tall yellow pony's legs were long enough to rise above the wreckage as she cautiously followed after.

The first big problem became evident when Twilight neared the broken door. Hanging off of one hinge in the frame, it did little to impede the two ponies on their entrance. But for two massively pregnant mares, it would be far more trouble. Laughing in quiet exasperation, Twilight tried to twist herself around the decayed wood, only for it to meet her stomach at whatever angle she attempted. It refused to swing the way it needed to, even on the one remaining hinge, and Twilight grunted and grumbled as she barely managed to pulls herself backwards out of the impediment.

A brief flash of magic from the irate, pregnant unicorn and a field of magic deftly ripped the lone hinge from the wall, and then seizing the entire door in purple sparkles, hefted it to the side and out of the way.

"G-Good job," Fluttershy said, her distant voice concerned with other things but still quick with words of encouragement.

Twilight replied with an irritated grunt, the next big problem stretching upwards before her. Stairs. She glanced back at her pregnant-looking self, quite unable to simply enjoy it, and then back at the winding staircase that would lead back to the surface. It would be unwise to teleport until she knew more about the mirror and its effects. Laying magic on top of magic was extremely dangerous with unknown elements involved. With a huff of determination, she put her right hoof forward.

It wasn't particularly hard, Twilight was thinking as she topped the first ten steps. She was just tall enough that she didn't scrape her oversized stomach on the stairs as she climbed, but only just so. As a quadruped, she had superior balance and weight distribution. The stairwell was wide enough that even a pony of her proportions had ample room to maneuver.

It was by the fortieth step, just past the estimated halfway point, that she began to have second thoughts. Most of them centered around just how heavy she was, feeling every ounce every time she put down her hooves. She was drenched in sweat, and much like a true pregnant stomach, her own illusion seemed to simmer with its own internal heat. And yes, her boobs hurt. The mirror had created quite the presentation, and she secretly wondered if it had drawn on her own experiences simulating pregnancy. Or the alternative, that her own spells were at least on par with those of a powerful, ancient artifact. The idea lifted her mood, but unfortunately did nothing to lift the rest of her.

Twilight could hear Fluttershy's labored breath behind her, and she guessed the trek wasn't much easier for the pegasus, even with her longer legs. "Are you... okay... back there?" Twilight puffed, feeling as if even her lungs were being squished by her pregnancy.

Although clearly winded, it seemed the pegasus was still faring better than the unicorn. "It's been a... strange day," Fluttershy answered,

Twilight had time between breaths for another laugh. "Tell me about it."

With little energy left for conversation versus climbing, Twilight lapsed into silence again, and Fluttershy was quite at home in the quiet. With slow but steady progress, they made their way back into the fresh air and sunshine.

Twilight Sparkle crossed the threshold of the final step, setting her hooves on level ground, sputtering her ragged breaths and stretching her sore muscles. She felt at once utterly miserable, and at the same time completely exhilarated. The swollen unicorn had conquered the stairs. The hard part was out of the way, and now she could enjoy the feeling of it all. For a bit, in any case, while she puzzled out the proper dispellation method. She found a particularly mossy rock to flop down on and did just that, lying on her side and smiling. There just weren't words to describe the visceral satisfaction stewing in her. "Just let me... catch my breath... and I'll... see if I can... undo this..." she called to her follower.

Fluttershy's reaction to escaping the stairwell was more subdued, or Twilight was still just bad at reading other ponies. The yellow pony was smiling slightly. She trod slowly over to where Twilight lay and did her own awkward sprawl onto the ground, flat onto her back, thrusting her enormous stomach into the air. A few shifts and shimmies for the pegasus to find a modicum of comfort, and the purple pervert drunk in every detail. "W-will we need to go back to the library?" Fluttershy asked, still smiling, but aware her day could still get much stranger.

Twilight was suppressing giggles, distracted from spellcraft to think of all the things that might happen if they did have to go into town. "No! I just need a little bit of rest. Besides, can you imagine us walking into Ponyville looking like this?"

Fluttershy seemed amused by the idea and answered with a demure giggle, "We'd give somepony a heart attack."

Twilight snerked, doing her own shuffle to find a more comfortable position to lay as the laughter jostled her overripe stomach. "We could head to Sweet Apple Acres and tell Applejack that it's really important we see Big Macintosh."

Fluttershy then did something entirely unexpected and put on her best Applejack impression. "Tarnation! Granny, git yer shotgun! Mac's been sowin' the wild oats!"

Twilight blew her laughter through her lips cracking up, her hooves going to her stomach as her sides literally ached. She winced, but continued to laugh, her mirth winning out over the slight pain. Collecting enough oxygen to actually respond, she mimicked Granny Smith, "Ah' reckon it's about gosh-darn time!"

Fluttershy finally broke into laughter as well, the two tittering at the slight to their poor unknowing friend. They let the mirth die away quietly and easily, both feeling able to actually relax, despite their circumstances, and fell into their own thoughts.

With brief respite, Twilight busied herself with the counter-spell, searching for telltale signs of enchantment to tug at and unravel the whole. The illusion was nearly perfect, layer upon layer with nothing to suggest that what she saw wasn't what she got. It was taking deeper and deeper magical sense and understanding to even suggest the two ponies were anything but abundantly pregnant mares. Twilight didn't want to worry her wary companion over such things if she could find a solution. Though if she were being honest, any other unicorn would need help to cancel this particular bit of sorcery. Through some clever usage of Eyes of True Sight, Word of Revelation, and Deveraux's Decompile, she was able to find where her real self ended and her fantastical self began.

Finally ready, Twilight struggled to her hooves, centering herself. With a flare of white light from her horn, she clove the enchantment from her physical body. Bereft of an anchor, the spell matrices degraded into gibberish and faded away into the ether. She'd done it. She was back to her normal, merely pudgy self. The ache of the day's exertions still clung to her, but the weight, the pressure, the pregnancy, and all the accompanying changes were gone. Again, she was torn. Jubilant in her accomplishment, disappointed at the end of the mirror's effect.

That left Fluttershy. The yellow pegasus was still obscenely swollen, with her stomach looming up above her prone body, and her wings slightly flared beneath her. She offered a congratulatory "Yay" and clapped her front hooves together. There wasn't a single movement the kindly pony could make that wasn't affected, and dominated, by her pregnancy. She was just too big, but she managed to retain all of her graceful femininity, and leaving her looking the very avatar of fertile motherhood.

Twilight swallowed and forced her focus, banishing all the stray thoughts running through her mind just then. Too bad I can't just leave her this way, Twilight allowed, before returning to the task. Her horn shone again and it was over just as quickly. Fluttershy's o-so-enticing stomach evaporated into higher dimensions.

Celestia's flaming tits, Twilight later thought.

That. That happened. That actually happened. That. Actually. Bucking. Happened.

That stupid, wonderful mirror had actually shown her a big, heavy, pregnant Fluttershy. Much later, once physically free of the situation and left to her own devices, Twilight's mind immediately went back to dwell on what she'd seen. That gorgeous winged pony swollen so massively, shuffling so shyly and awkwardly, knowing she shouldn't be that damnably pregnant. It was identically maddening and alluring.

Twilight would need to return later to puzzle out the mirror's exact effect, after she'd reviewed some pertinent texts on magical artifacts and brushed up on the syntax of thousand-year old enchanting matrices. Under normal circumstances, the librarian would call that a fun and productive night. She had a cup of tea, a cleared space on her desk, a writing pad, a fresh quill, multicolored ink, and a pile of books to sort through. She should be in her groove. But with what she'd seen, her mind just wouldn't let her focus where she needed to. Her thoughts continually drifted back to the ponderous, pregnant pegasus...

Author's Note

You're being subjected to my headcanon. Absent animation budgets, the ponies must be different heights. In pony equivalent, Applejack is 6'3". Fluttershy is 5'10". Rarity is 5'9". Pinkie is 5'5". Dash is 5'2". Twilight is the shortest, a 5'0" gremlin.
