Author's Notes:

First thing I want to get off my chest. I may or may not choose the ponies that get Age-Regressed in this fic after chapter 1. So I'm gonna leave it up to you guys to decide who I should Age-Regress in this fic. Leave your suggestions in the comments section below, I hope you enjoy my latest work.

Equestria, home of ponies and pets and mythical creatures alike. A planet where horses flourish and live in peace and harmony. It was only 3 months back when these ponies mastered Age-Regression. Able to age and youthen anypony with no problems at all. Ever since, the ponies have become technologically supreme and now live in the future, today.

Ponyville. A once quiet amish town, was now a city with metallic streets and roads. The houses had been converted into skyscrapers and all looked pretty interesting from everpony's point of view. Most of the buildings had neon lighted outlines, which glowed brighter at night. And there were a few tv screens advertising products, always changing the advert once the first one had finished.

Twilight was walking down the street with her saddlebags at her sides. She was once more gazing at this town turned city and was looking for somewhere to spend her day.

"Let's see here." She said as she examined each building carefully.

"I could always go for some pampering." She said as she looked at a nearby spa with a neon sign, "Or maybe do some shopping." She was gazing at what looked like a megamall with a lot of neon on the outside and interesting stalls and shops inside.

"Wait a minute, what's this?" She said as she saw a building right next to her, "Memory Lane: A Trip Back To Your Childhood. Wonder what that means." With that, Twilight stepped inside through the mechanical doors.

She saw a lightly coloured reception with a few pylons in each corner. Each pylon had rainbow coloured neon running down it and it also seemed to travel down into a deeper part of the building. She came up to the reception and ringed the bell with her hoof.

"Hello." She said through the door behind the reception, "Anypony there?"

"Oh, hi." An earth pony walked out of the door and stood behind the receptionist desk with a smile on her face, She was cream coloured with brown hair and a ponytail at the back of her mane, "I'm Mrs Love, welcome to Memory Lane, darling."

"Hello to you as well." Twilight responded, "My name's Twilight Sparkle, I noticed this was a new business as I was walking down the street, so I was wondering what you do here, I mean if that doesn't offend you in anyway."

"It's no trouble at all, Twilight." Mrs Love said to her, "That's what they all say when they come here. This place specializes in Age-Regression, enabling ponies to return to their childhood states. The price is 5 bits, but the service is exceptional." She walked out from behind the desk and came closer to Twilight, "So, do you want to take a trip down memory lane?"

"Well, I wasn't really planning on doing anything else anyways, so, yes. I'd love to." Twilight said as she took out some bits from her saddlebag and placed them in Mrs Love's hoof.

"Good to hear that." Mrs Love quickly took the bits and dropped them in an automatic cash register, she then pushed a few buttons which then issued a little card to Twilight, "Oh yes, it's customary to give each new customer a loyalty card, pay for 6 regressions and the 7th is free."

She then hoofed Twilight a little sticker to place on the card. Twilight carefully used her magic to affix the sticker onto the first box, making sure to get the star shape perfectly in the outline.

"Now then, let's walk." She led Twilight down a corridor which came to a little room which was smaller than the other one, but still had the neon pylons in the corners. Other than the pylons, Twilight saw a machine which went through the wall at the end. It was cylindrical from their perspective once they got in, "If you could just drop your saddlebags in the slot there, we can begin."

Twilight put the card in her saddlebags and then dropped them into a little slot. The bags slid down the steel shaft before vanishing from her sight altogether.

"Are you sure you've mastered Age-Regression?" Twilight asked once she stepped into the machine and shut the door behind her, "I just want to know, that's all."

Suddenly, the closed capsule glowed brightly and made a little humming noise which gradually increased in pitch, Mrs Love then appeared on a screen above her, pushing some buttons, "Don't worry, the effects only last for 24 hours. Nothing to worry about in the slightest." A hatch opened in front of Twilight, revealing a swirling vortex of rainbow coloured energy, "Just close your eyes, and when you open them again, you'll be a cute little foal again."

Twilight did as she was told and shut her eyes, the steel she was standing on, moved forward, into the vortex of energy. She was conveyed all the way to the end of the steel, from this part on, she was being propelled through the vortex at a moderate yet fast pace, she didn't feel anything at all, but her legs, neck and horn got smaller, as did her face and muzzle. Her cutie mark vanished in the vortex and was digitized on another of Mrs Love's computer screens next to the one she was using earlier. Twilight mumbled something, which then turned into high-pitched foal noises and gurgles. And with a final flash of light, Twilight was out of the vortex and sitting in a new room.

Mrs Love walked through another door next to her console and walked into the room that Twilight was in. She was accompanied by two other ponies, a unicorn stallion and a pegasus mare. They came to Twilight, who now had her eyes covered with her foal hooves as well as her closed eyes.

"OK then, you can open your eyes on three." Mrs Love told the foal Twilight as she took Twilight's hooves by her own, "One... Two... Three." She gently lowered Twilight's hooves and at the same time, Twilight opened her eyes and was instantly amazed and giggling with what she saw.

The new room Twilight was introduced too was massive and lightly coloured, with some foalish wallpaper and padded floor. The room consisted of a massive pile of padded shapes in the middle, for foals to climb all around and hide in. around the shape pile was a range of foalish toys and blocks. There was a line of cribs at the back, taking into account that the treatment lasts for 24 hours and in another side of the room was a row of changing tables, each stocked with diapers and foal powder, in case the customers made any little accidents whilst they played.

"Beautiful, isn't it?" Mrs Love asked Twilight, who immediately nodded and clapped, "Oh yeah, almost forgot. We need to get you changed."

Mrs Love and the unicorn carried Twilight over to the nearest changing table and laid her down, The unicorn opened the diaper and sprinkled foal powder onto it. before levitating it onto Twilight's flank. Once he was satisfied with the diaper's position, he made the three ends meet and tied the tapes up tightly so that it didn't fall off of Twilight as she played.

"There we go, Twilight dear." Mrs Love cooed at her, you're clean, happy and healthy. Now you can go play."

Twilight said something, but it was foalish nonsense since the vortex had destroyed any and all speech she had left in her. She quickly shrugged it off and ran towards the shape pile, climbing up the tower and crawling through the hidden passages and pipes, making foal-like giggles and laughter all the while.
