Zecora quickly grabbed every magic analyzing artifact off her shelves, doing everything she could to find out what, exactly, had just happened, and how - if at all - she could reverse it. Once she'd begun getting information, she began correlating it in her mind, not bothering to rhyme her thoughts as that was a waste of time...time she quickly realized she didn't have.
Well, the good news is that they're safely over there, she thought silently. The bad news is that they are foals, somehow. Even if I managed to bring them back, there's no telling what it would do to them, since the original transfer was a mixture of magics from both sides. Also, the world I'm observing...their timeline is not synched up to Equestria's. So when this portal closes, even if I manage to open another window, there's no guarantee it will be to the same moment...and the portal is closing, and fast.
Realizing she only had moments, if that, to try and help the young ponies, she did the only thing she could do...have faith in another practitioner of good magic to safeguard them until a solution could be found. Quickly writing out a letter, she dropped it into the cauldron. Moments later, the portal closed.
Desperately, she began brewing the window potion anew, hoping against hope she'd be able to find the same world soon.
Uncle kept his ears covered against the wailing of the three tiny creatures, trying to focus his senses so he could at least figure out what was happening. Finally, unable to take it, he shouted at the top of his voice, "AIYAH! Uncle cannot think in this noise! Quiet!" Much to his surprise, the din immediately ceased, the three tiny creatures staring up at him in shock. He did his best to smile reassuringly. "Much better."
Kneeling down, he began to examine the three creatures. "Hmm...a tiny bright colored horse?" he asked, picking up the yellow one. "Not what Uncle expected to see." The tiny foal giggled as he held her. "You are easily amused," he chided, setting her back down. "Uncle is not...a pegasus?" This brought more giggles, and not just from the tiny winged equine he'd picked up. Frowning, he set her to the side with the other. "And now what about..." His voice trailed off as he finally got a clear look at the last foal. "...aiyah..."
He stared in awe at the tiny white filly, who squirmed in his grip, plainly uncertain how to react to the attention. His eyes, however, were locked on her horn.
"Qi-lin..." he breathed, completely awestruck. "To think Uncle would be visited by infant Qi-lin...such great omen..." He gently set her down with the other two. "To come with a Qi-lin...you three are all creatures of great good magic...Uncle is truly blessed for such a visit-ow!" He rubbed his head as he picked up the scroll, made of paper unlike any he'd encountered before, bounced off his head, the binding of chi magic releasing the scroll as his eyes fell upon it. Lifting it, he read the contents.
Their names are Apple Bloom, Sweetie Belle, and Scootaloo
All three are my dear friends true
From one sage to another, I beg of thee
Please tend to them till they return to me
Uncle rubbed his chin thoughtfully. "Hmm...the scroll was bound by good chi. A good chi wizard like myself worries for you." He shrugged and smiled. "It is hardly my strangest quest as a Chi Wizard," he admitted, sitting down before the three foals. "Now...which of you is which? ...Apple Bloom?"
The yellow foal squeaked happily, her brown eyes shining happily.
Chuckling, he reached out and stroked her between her ears. "Sweetie Belle?"
The unicorn let out a high pitched squeak as she clambered into his lap.
Uncle smiled widely as he gently stroked her mane. He then scooped up the pegasus. "And you must be Scootaloo. Hmm, odd names."
Scootaloo stuck her tongue out at him.
Shaking his head, Uncle put the three foals together in front of him. "Uncle will take care of you three. But you must be well behaved and obey Uncle's rules. Understand?" Looking back down, he saw that all three foals had vanished. "Aiyah!"
The first thing he did was rush to the door, making sure it was closed and locked. After that, he raced through the rest of the shop and upstairs apartment, moving as fast as he could as he checked each and every window was closed and locked. Once he was certain that the three couldn't get out of the shop, he began searching for them.
When he did find them, however, he wished he hadn't, as they had made their way into his chi laboratory. "Aiyah!" he screamed out in panic, immediately getting their attention. "Apple Bloom, those potions are dangerous, not tasty treats!" Apple Bloom dropped the vial she'd been trying to drink from, causing it to break and the liquid inside to burst into purplish gas that, thankfully, only filled the room with a sweet scent. "One more thing! Sweetie Belle, that is an ancient and dangerous artifact, not a scratching post!" Sweetie Belle sank to the floor, taking her hooves off the large mystic blade she'd been trying to scrape her hooves against. "One more thing! Scootaloo, the ceiling is not for walking!" Pouting, Scootaloo dropped off the ceiling, landing in his arms.
Taking the three of them, he pulled them out of his laboratory, wanting to try and get them under control. Taking another vial, he drew a line across the doorway. "Yu Mo Gui Gwai Fai Di Zao...Yu Mo Gui Gwai Fai Di Zao..." Once the line of powder began to glow, he turned towards the three fillies, only to see them walk right over the line, Sweetie Belle pausing to eat some of the powder. "...right, creatures of good magic..." Uncle reminded himself, grabbing the three of them by their tails and pulling them back out, this time shutting the door. "Do not go in there," he instructed them firmly. "It is too dangerous!" He paused. "Uncle has the feeling that is going to be said a lot in the future..." A loud crash interrupted his musings. "Aiyah! Scootaloo, that was rare Ming vase, not a jungle gym!"
