Twilight Sparkle was asleep in her room in her castle when she suddenly heard what sounded like vibrating. She immediately woke up with a start! "Oh no, did I leave that on?!" She opened her nightstand to see it wasn't 'it' that was vibrating, but rather Sunset Shimmer’s enchanted notebook. "Oh thank Celestia." The young princess sighed as she grabbed the notebook and started to read:

Dear Princess Twilight,
Hey, its me again, Sunset Shimmer.

I just wanted to tell you that the mirror on this side is-

"Sunset Shimmer, what are you writing?" A teacher asked Sunset as everyone in the class turned to look at her.

"Oh, um, I'm just... writing something in my notebook for later." Sunset nervously answered and blushed. Despite all the weird happenings that tended to occur around her and her friends, she preferred not to share knowledge of the other world with everyone.

"Give it to me, please. The classroom is for learning, not sketching," The teacher instructed, clapping her hands. A reluctant Sunset got up from her seat, walked to the front of the classroom, and handed the notebook over to the teacher. "You can get this back at the end of the day, now sit back down, please.” The teacher sternly declared and Sunset obeyed.

Unfortunately, since Sunset had been cut off mid-writing, Twilight was stricken with concern and worry! "What the.... Spike!" She yelled!

Spike jumped up and fell back down making his basket tumble over as he shook himself awake!

"What is it, Twilight? Did you leave 'it' on again?" Spike questioned as he walked over to Twilight’s bedside.

"No, it's even worse!" Twilight declared as she pulled the notebook in front of Spike. Spike rubbed his eyes before reading what the page said.

"What? It’s just-" Spike began.

"It’s not done!" Twilight yelled at the top of her lungs.

"So, she could have just-" Spike began to suggest.

"She could have gotten hurt, or been abducted by someone!" Twilight protested.

"Well, what are we going to do?" Spike asked. “Are we going to that other world?”

"Not yet, there’s no telling who or what’s waiting on the other side for us. We’ll need backup,” Twilight declared. “Just get everypony to come here tomorrow."

"Everypony in Ponyville? Are we recruiting an army?" Spike wondered.

"No, not Everypony in Ponyville, just our friends,” Twilight corrected. “You know: Applejack, Fluttershy, Pinkie Pie, Rainbow Dash, Rarity, and Starlight."

"Oh, okay." Spike yawned a bit. He figured it was probably best just to go along with Twilight’s plan. Chances are it was nothing, Sunset had just run out of ink mid writing. “It’ll all be cleared up when we go to the human world, and meet Sunset.” He thought. Besides, it might be a nice vacation.

The next morning Twilight gathered the others in the throne room, pacing back and forth. "So, you’re probably wondering why I called you all here-"

"No, Spike explained everything." Rainbow Dash spoke up.

"So then, you know that Sunset Shimmer didn't finish a message to me, and I think that something could have happened to her?" Twilight asked.

"Yep, everything." Rainbow nodded.

"So than you know that Spike and I are going to go through the mirror?" Twilight added.

"That's something we didn't know," Rainbow remarked, then she got up and punched the table while saying. "And I'm guessing that only you and Spike are going again?"

“Actually, no, not this time,” Twilight answered. “I don’t know what could’ve happened to Sunset, but I specifically asked you all here so that you could accompany me. Whoever or whatever caused Sunset to stop mid-sentence won’t be a match for all eight of us.”

“Look out, humans!” Pinkie eagerly declared as she stood up on the table map. “Here come the ponies!”

In the human world, all of the Rainbooms were sitting around the stone pedestal that housed the mirror, the horse statue still hadn’t been replaced. Sci-Twi (as her friends had nicknamed her, so as to avoid confusing her with the pony Twilight they’d known) looked at Sunset. Noticing the troubled look upon her friend’s face she asked. "Hey, Sunset, what's wrong?"

"My first period teacher took my notebook and said I can't get it back until the end of the day." Sunset explained.

"So, it’s just a notebook." Sci-Twi commented.

"Yeah, but it's also the only way to get in contact with the other world. It’s magically enchanted." Sunset explained.

"Oh! Well if it’s really important then let’s go get it." Sci-Twi declared.

"We can't, she locked it in her desk." Sunset grumbled.

"Did you forget we have magic necklaces?" Sci-Twi grinned. “Getting it out will be a snap.”

"Did you also forget that Principal Celestia and Vice-Principal Luna told us we can't use our magic unless the school is getting attacked?" Sunset remarked as she arched an eyebrow upward. “Most people still don’t know it’s on the loose, and we don’t wanna cause a panic. We have to abide by the rules, or we could get expelled.”

"Oh, yeah. I mean, I doubt we would, but there’s no sense revealing our secret. Most people seem intent on forgetting the times Equestrian Magic showed up here," Sci-Twi declared. Just then the bell rang. "Shoot! It’s second period already?! I can’t be tardy!" The Rainbooms all ran off, hoping to make it to their classes before they were late.

"Finally." Sunset said out loud as she walked to her first period room, the end of the day had taken forever to finally arrive. Once she got there, she was relieved to find the teacher from this morning still at the desk.

"Oh, Miss Shimmer, are you here for your notebook?" The teacher asked.

"Yes." Sunset nodded as she walked over to the desk.

The teacher undid the lock and grabbed the notebook. "Don't let me see this notebook during class again, or it’s going to stay with me until the end of the semester, got it?" She threatened as Sunset took hold of the notebook.

"Yes, Mrs. Vandenhoff." Sunset nodded and gulped as she ran to the front of the school, where her friends were waiting for her.

"Hey, did you get your notebook?" Rarity asked. But before Sunset could answer sparks started to shoot out of the top of the pedestal in an alarming fashion!

After about a minute or so of sparks coming out of the top of the pedestal, seven human babies and one puppy fell out of the mirror! The Rainbooms rushed over and looked at the babies. The babies were all asleep as was the puppy. But the babies looked strangely familiar. "I don’t believe it, they look like us." Fluttershy commented as she picked up the baby girl that looked just like her.

"That's because they are us." Sci-Twi declared as she picked up the baby girl who looked like her (but did not have glasses).

"But that can’t be. The last time Princess Twilight was here she was a teenager, not a baby. What the heck happened?" Applejack asked as she picked up the baby girl who looked like her, but had a brown stetson hat that was now way too big for her.

"Oh my gosh, it’s a baby me!" Pinkie giggled as she grabbed the baby version of herself. “Except my hair was straight when I was born, Mom says it suddenly curled up one day and never went back to normal after that.”

"So, these are ourselves from the other world, but they’re babies. What are we going to do with them?" Rainbow Dash asked, picking up the baby version of herself. “And I don’t recognize that one girl, she looks like Twilight but her skin and hair look way too different.”

"Well for one we should get them some clothes, and some diapers." Rarity suggested as she picked up her baby self.

"I don't know how to put a baby into a diaper, do any of you?" Sunset asked as she picked up the baby Starlight.

"I um, I took a course on baby care before." Fluttershy admitted, then the baby version of herself woke up

"Uh, hewwo?" Baby Fluttershy asked as she looked around, then up at the other her. “Why evewyting so big?”

"Oh, hi little one. Did you have a nice nap?" Fluttershy cooed at the baby in her arms.

"Wittwe one, I not wittwe," Baby Fluttershy protested before she heard her voice. It sounded high pitched and childish. "Wha's wong with my voice?"

"Um, Fluttershy," Sci-Twy declared and both Fluttershys looked at her. "No, the small Fluttershy."

"Oh." The teenaged Fluttershy replied as she looked away.

"Fluttershy, you’re from the pony world, Equestria, right?" Sci-Twi asked the baby Fluttershy.

"Yea, why?" Baby Fluttershy asked.

"Well, I guess when you came through the portal, you became a baby somehow and so did the rest of your friends." Sci-Twi commented.

"A..... A baby?" Fluttershy asked, thinking she’d miss heard Sci-Twi somehow.

"Yes, a baby. A baby human though, not a baby pony." Sunset explained.

"I'M A BABY?!" Fluttershy yelled in a squeaky voice and then started to cry, which woke up the rest of her friends and they all started to cry too.

"We can’t leave them out here! We should bring them to Principal Celestia before someone notices them!" Sci-Twi shouted over the cries of the baby in her arms.

"Yeah, good idea." Sunset declared as they started to run to the principal’s office of Canterlot High.
