All six ponies were traveling through the time hole.
"Equestria present. Canterlot Castle." The screen read before a white glow came at the end of the time hole trip. The six of them became engulfed by the glow.
The six of them exited the time hole and they reappear in one of the bedrooms.
"Alright girls, let's go find the doctor and our friends." Applejack said.
"Could we go to the shop first and get some equipment we might need?" Rarity suggested.
"Well alright, but just for a few minutes."
The six of them walk through the castle to the shop. Five minutes later, they arrived at the Shroom shop. "Welcome to the Shroom shop! Care to buy some gear?" The cashier asked.
"Yeah we'll takes six EXP badges and that'll be all." Rainbow Dash said. The clerk gave them the badges and Rainbow Dash gave him the required amount of bits.
"Come on back!" The six of them leave shop and head off to find the doctor. They got back to the room where the doctor was working on the machine with the rest of the mane six and Spike right by the machine.
"We're back!" Rainbow Dash said.
"About time you ladies showed up!" Doctor Whooves said facing them.
"Yeah, it's great that you're all okay." Twilight said.
"Well we kinda ran into some trouble along the way." Applejack said.
"Oh, you ran into some persnickety obstacles, did you?" Doctor Whooves asked them.
"Well you could say that." Rainbow Dash added.
A few minutes later, they explained everything that happened through the Everfree Forest and the Vim Factory.
"I am deep in a shame cycle doctor. We nearly had a pair of fragments, but... That young changeling princess made off with them both." Stuffwell told him.
"That's terrible!" Fluttershy said.
"I see. Well no need to get your leather lathered. There've been new time holes popping up faster than toast on Sunday morning!" Doctor Whooves said. The screen shows that two time holes popped on the top floor and two more on the current floor they were on. "And I'll tell you, one of them is giving off tremendous Cobalt Star energy readings. I have no doubt that's the time hole you want! Yep! That's where Young Princess Chrysalis made her escape!"
"Where is the time hole that we need?" Rarity asked.
"I think it's on the top floor of the castle." Twilight replied.
"Applejack! Rainbow Dash! Rarity! We must chase!" Stuffwell said. "We MUST have redemptitude!"
"Look now, before you rush off, I think it'd be wise to survey the rest of the castle. And another thing, there's a noisy feller from the past running around with a baby." The doctor said.
"That must be Mane with Filly Celestia." Twilight realized.
"He and Mane are in the garden. Could you make sure there's no hoopla out there?"
"Of course! Ya'll want to come too?" Applejack asked her friends.
"Okay." Fluttershy answered.
"Sure." Twilight agreed.
"We can all go together." Pinkie Pie suggested.
The mane six, along with the past Applejack, Rainbow Dash, Rarity, and Spike left the room. They walked down the hall and head straight for the garden. By the time they got to the garden, they found the young Monsieur Mane standing on his elder self while Filly Celestia was in her pink filly carriage crying.
"Look lively, now, elder me! We must please the princess! Put your back into it!" The younger Monsieur Mane tells his elder self.
"I-I'm absolutely spent." The elder Mane said.
"Pull yourself together, man! Smile, I say! Smile!" The elder Mane struggles to make a smile, but it was no use. The mane six, Spike, and the three fillies go over to Mane and talk to them.
"What's wrong?" Twilight asks them.
"Twilight, it appears that the princess... She won't... She won't stop crying!" The elder Mane explained to her.
"Is there anything we can do to help?"
"No need Twilight! We've not yet begun to amuse!" The younger Mane tells her. "Now hooves out elder me! 3, 2, 1!"
"MONSIEUR TWIST!" Both of them were spinning around fast. The mane six and Spike were confused with what they were doing. The three fillies began jumping up cheering, and Filly Celestia began to calm down and laughed happily as she clapped her hooves.
"Jolly good, elder me! Our charge is giggling!" The young Mane said. Rainbow Dash goes in closer and closely observes their move from all sides. She flew over to Applejack and tells her the idea. Applejack thinks about it for a minute as both Monsieur Manes stopped spinning. The elder Mane was feeling dizzy and fell over while the younger mane landed safely. Rainbow Dash and Applejack both went over to Monsieur Mane and told him their idea.
"Oh, Mistresses Applejack and Rainbow Dash! Grown up have you? I'm quite up to speed on our crisis. Bit of a sticky wicket." The younger Mane said. "The older Princess Celestia, the kingdom... You must save it all. And I shall be right here as you do, rooting for victory!"
"I'm sure you will. By the way, is there any chance you could teach us how to do that move you two just did?" Rainbow Dash asked him.
"What's that you say old bean? You wish to learn our move?"
"Yep!"
"Well if it will help you fulfill your duties, of course! It would be an honor and a privilege! Come! Practice awaits!" He walks over to his elder self. "Chin up, elder me! Mustn't falter now!"
We see both Manes in the practice area with Applejack, Rainbow Dash, and Rarity.
"We've taken to calling this technique a Spin jump!" The elder Mane tells them. "You'll soon see precisely why. Mistress Rainbow Dash begins the move."
"Are we all quite ready? Good. Commence the instruction!" The young Mane instructed.
"First, press R to make Mistress Rarity's icon change into the Spin Jump icon." The elder Mane explains. "Next, press B so Mistress Rarity leaps up and perches on Mistress Applejack. Then, press L to have Mistress Dash's icon the same as Mistress Rarity's. Up next, press A and Mistress Dash will be on top of Rarity."
"Wait! Are you saying Rainbow Dash will be standing on ME?!" Rarity asked with a shocked expression.
"Of course. From there, press B again to make the three of you whirl about and rise skyward!"
"And now it rather academic!" The young Mane said. "Press a direction on + to fly in said direction. Huzzah! This marvelous technique will allow you to cross gaps where mere jumping proves lacking. Have at it!"
The three of them complied with the instructions. Rarity hops on top of Applejack, and Rainbow Dash is on top of Rarity. They were all spinning together and lifted themselves in the air slightly, and they managed to get across all four gaps on the first try and reach the end.
"Yes, yes, jolly good show!" The younger Mane complimented. "I trust you'll use this to your advantage in the field as well."
We are now back in the previous room.
"I should think this Spin Jump will give you access to some awfully hard-to-reach areas." Mane tells the three of them.
"Now, time to be off ladies! Utilize the new time hole! Rescue our Princess!" Elder Mane said.
"We will." Applejack said. The mane six, Spike, and the three past fillies leave the room. They all head through the hallways, go up the stairs, step on the button, and open the door. They head to the right and they all end up in a library.
"Oh my goodness, there's a library here?" Twilight gasped.
"Oh boy, here we go again." Spike said.
"Of course Twilight would be interested in this." Rainbow Dash added.
"Well where's the time hole?" Fluttershy asked.
"It's up there!" Rarity noticed pointing on top of the bookshelf. "That's where we should be heading." Applejack, Rainbow Dash, and Rarity head on top of the bookshelves and found another time hole.
"Good luck!" Spike said.
"Please be careful." Fluttershy said.
"We hope you make it back okay." Pinkie added.
"Ya'll ready?" Applejack asked her two friends.
"I'm ready." Rarity agreed.
"Let's go find the princess." Rainbow Dash added. Once again, the head into the time hole and disappear into the light.
