Principal Celestia was in her office, packing up for the day when she started to hear strange cries coming from the halls. She got up from her desk and walked to the door, opening it she saw the Rainbooms, with what appeared to be infant versions of themselves (aside from one baby girl who Celestia didn’t recognize). "What’s all this about?!" Principal Celestia inquired over the cries as she let the Rainbooms come into her office. “Who are these children and where did they come from?”

“It’s a long story, Principal Celestia,” Sunset tried her best to answer. “I think they’re Princess Twilight and her friends from Equestria, but they got turned into babies somehow.”

"You're saying that these are the pony version of all of you?" Celestia asked as the babies stopped crying. They were looking at the strange new grown-up in their midst with varying looks of curiosity.

"Yes, or at least that seems to be the case," Sci-Twi answered as she pushed her glasses into place.

"But how we babies?" Baby Twilight asked.

"I think it might have something to do with the statue being broken," Sunset explained.

"So if we go thwough the miwwow, we be big ponies again?" Baby Fluttershy asked. Just then the door opened, and a familiar looking puppy came into the room.

Spike woke up and looked around. "Definitely in the other world, but where's Twilight?" He asked himself. Then from out of Sci-Twi’s bag came another dog that looked the same as the puppy, but taller.

"Why are you talking about Twilight?!" The dog asked as he ran to the puppy Spike. "And how are you talking?"

"No, the question is how are you talking?" Puppy Spike asked.

"I went through a portal to another world a few months ago, then when I came back through I could talk. Now how can you talk?" Dog Spike demanded.

"I’m from that other world, in fact, I’m a dragon!” Puppy Spike boasted. “I just came here with a few friends, and my Twilight, because Sunset never finished a message to my Twilight and she freaked out over it."

"Ah, Twilight," Both dogs said at the same time. "By the way, my name’s Spike. Hey, cool, we have the same name!"

"Spiky!" Baby Twilight cheered as she hugged the puppy next to her. Principal Celestia and the teenager couldn't help but aw at the sight.

Spike got out of the hug and looked at Baby Twilight. "Twilight, is that you?"

"Yeah, it me, me baby." Baby Twilight answered with a blush.

"I can see that. Looks like we’re all younger." Puppy Spike replied.

"Back to what we were talkin’ about before that cute little surprise, do you think that if we sent them all back through the portal, they would turn back to grown-ups?" Applejack asked Principal Celestia.

"I guess you could try. Just be careful not to be seen," Celestia instructed, then the teenagers picked up their baby counterparts and walked out of the room. Celestia waved until they were gone. “I don't know why they ask me, I don't know anything about Equestrian Magic.” She thought to herself.

"So, if this works, you'll all go back to being grown-ups." Sunset nervously commented as she put Starlight onto the ground, and the rest of the Rainbomms put their respective baby counterparts on the ground too.

"Otay giwws, you weady?" Baby Twilight asked.

"Yeah! Wets do tis!" Baby Rainbow Dash declared! She started to crawl to the portal, but as soon as she touched it she was pushed back. She tried again, only for the same results to happen. No matter how many times the portal kept pushing her back. "Why I no go thwough the powtaw?"

"I don't know, I can do it just fine," Human Rainbow Dash declared as she stuck her hand through the portal "See?" She pulled it back and picked up her baby counterpart.

"I guess that babies can't go through for some reason," Sci-Twi commented.

"But we stuck hewe then!" Baby Rarity declared as she started to cry. “Of aww ta wowst tings that couwd happen, tis is: Te, wowst, powwisbwe, ting! I mean it tis time!”

"How we suppose to teww Pwincess Cewestia we stuck hewe?" Baby Twilight nervously asked with a gulp. “Wha if she needs us fow someting?”

"Well, since my journal isn’t forwarded to anymore, I’ve got an idea. It’s risky, but it should work." Sunset declared as she stuck her head through the portal. "Hello? Princess Celestia?!" She yelled.

From the other side of the portal, Princess Celestia (who was looking at the mirror in Twilight’s castle) saw Sunset's head sticking through! She rushed over! "Sunset Shimmer, it’s so good to see you!” She happily commented. “Well, your head at least."

"Yeah, it’s good to see you again too, princess, but I have some very bad news," Sunset glumly replied. “But it wasn’t me.

"What are you talking about?" Princess Celestia commented.

"When Princess Twilight and her friends got here, they were babies," Sunset explained.

Princess Celestia's calm expression shattered completely. "Send them back through!" She demanded. “We need them here!”

"We can't, princess," Sunset answered with a gulp.

"What do you mean 'we can’t’?" Celestia demanded. “Sunset Shimmer, you know how important Twilight and her friends are to the safety of Equestria.”

"When they tried to go back though they just got pushed back, they’re stuck here!" Sunset explained.

“I see,” Celestia commented. “Clearly something is wrong with the portal. But we need a better way to communicate. We can’t risk you or anyone else being affected or trapped by the portal.”

"I know, but I don’t know what else to do. You’ve gotta help me, Princess Celestia!” Sunset Shimmer pleaded. “I’ll even come back to Equestria to help you solve this, it’s my fault Twilight and her friends are stuck like this. They never would’ve come here if not for me.”

Celestia shook her head. “Sunset, you can’t leave the human world! You’re the only one with any knowledge of Equestrian magic. Your help is needed there, especially with Twilight and her friends stuck as babies,” She then reassured her former student. “I’ll pick up your old journal here, and try to keep in touch with you through there. But for now, you must go back. I'll be here if you need any advice."

"Well, now the princess knows." Sunset declared as her head emerged from the portal.

"How you know she knows?" Starlight asked Sunset. “Uh, I Starwight Gwimmer by da way, Twiwight’s student.”

"Oh, I didn’t know Twilight had her own student,” Sunset chuckled. “But I just talked to Princess Celestia through the portal. She’s gonna try to stay in touch with me through my journal, and we’ll work to find a solution." She then bent down and picked up Starlight, which was a mistake, because Starlight started to pee.

"Oopsie, me no mean to do that!" Starlight replied as her urine got all over Sunset's jeans.

Sunset tried not to be offended or grossed out, something like this was bound to happen soon or later. "It’s okay, you’re just a baby and you can’t control it. But I think that we need to go you all some 'protection' until we know how much you’ve regressed." She replied. She didn't want the babies to freak out over being put back into diapers

"We definitely need to get them some protection, but I don't have any money for that stuff." Rarity replied.

"Weil, Pinkie could probably just use some of the Cake Twins’ spare supplies, but I could use some of my money to cover the expenses for the rest of us. Who will take them home though?" Sunset asked.

"I guess we'll all take one of them home. Each of us takes home their baby counterpart, and you’ll get Starlight." Rarity suggested.

"I call Mini Pinkie!" Pinkie yelled as she jumped up!

"Me guess me go with big me." Baby Pinkie commented.

"I'm okay with the idea of bringing a baby home, but if my dad sees baby me, he will freak." Sci-Twi declared.

"Yeah, so would Granny Smith." Applejack chuckled.

"Wet me guess, she give the speech of how when she was your age, she no go and hang out with boys, and tings like that." Baby Applejack teased.

"Did you get that speech when you were a teen?" Applejack asked her baby counterpart.

"Yeah, onwy it was more cowts." Baby Applejack blushed.

As the rest of the Rainbooms divided up who would go with whom, Principal Celestia came running out of the school. "Good, you’re still here." She panted as she came up to the group.

"Yeah, we’re still here, and this one had an accident on my jeans," Sunset explained as she pointed at baby Starlight

"Me said me was sowwie." Baby Starlight blushed.

"We need to get some ‘things’ for them, but we don't have a way to get to the mall, or any baby store," Sunset explained.

"I can give you a ride, and pay for the stuff." Principal Celestia encouraged.

"Okay, thank you so much. You’re a lifesaver!" Sunset said to Principal Celestia, then looked at her friends. "I guess I'll go."

"No, you stay here and change your pants. I'll go and help get the stuff." Rarity replied.

"Okay, I guess we'll see you later." Sunset declared.

"You girls get the babies into the school for now. We can worry about taking them home later." Principal Celestia instructed, and then the Rainbooms (minus Rarity) picked up their babies and walked into the school.

"Alright, let’s get some diapers." Rarity declared as she and Principal Celestia walked to Celestia's car.
