Huzzah! More shitposting!

I'll use Diane instead of Adam and address Diane by her new gender from this chapter onward. I hope y'all enjoy the chapter!

A Deluge of World Ending Proportions

Getting used to the addition of two new legs was somewhat difficult. Diane hadn't fallen over but she did clumsily stumble quite often on their short trip back into town. Pinkie didn't seem to notice due to hopping ahead of them with her eyes closed, but Twilight had thrown a few confused looks her way.

"Oh! This will be so super-duper fun!" Pinkie squeed in excitement, she started hopping around her new twin sister, each hop was accompanied by a cartoonish spring like sound. "We can do so many things together! I just can't wait! Oh, and I can't wait to show you to the rest of my family! Our family!" She then scooped Diane up in a big hug. Diane chuckled at her new sister's antics. She seemed to be a bit more hyper since the discovery of a new addition to the Pie family.

"I still cannot believe you're real." Twilight was walking behind the two pink ponies. Her hair was a lot more frazzled than twenty minutes ago, and her left eye kept twitching ever so often. Twilight blinked and suddenly Diane appeared next to her, wrapping one of her hooves around her back. It was as if she had teleported behind her, but that couldn't be possible, she wasn't a unicorn.

"Relax darling." Diane gave her best impression of Rarity that she could. "Everything is going to be fine. It's not like an exact copy of Pinkie Pie appeared in town." She then patted her back and joined Pinkie ahead of her. Another audible ping noise came from yet another strand of hair that unaligned itself.

"So, where to now? Back to Sugarcube Corner?" Diane turned to address Pinkie. "Yepperooni! Just need a few supplies before we can start." Pinkie gave a wide smile. As they walked through Ponyville many ponies turned their heads over towards the two Pinkie's walking side to side. Many of them giving confused looks at them. However none approached. The small group walked back to Sugarcube Corner where the local bakers resided. Diane could spot Mrs Cake manning the counter. Or would it be ponying?

Her eyes spotted Diane. "There you are Pinkie, I thought it was your turn-" The words died in her throat when Pinkie walked into the shop. "I'm sorry Mrs Cake but I had something really really important to do." Mrs Cake's eyes widened at the two Pinkies standing in her shop. "I want you to meet my new twin sister, Diane!" Pinkie pulled her sister into a big hug and pushed her towards the now confused baker.

"W-What? How?" The baker was entirely surprised by Diane until a look of fear flashed on her face. Her gaze slowly turned to the purple princess who walked through the front door. "Princess? Are they?" Mrs Cake pointed a shaky hoof at the two pink ponies.

"No. They aren't changelings." Twilights brow furrowed at Mrs Cake when her doubt was turned her way. "And neither am I." The alicorns horn glowed and exactly fifteen muffins behind the glass display counter turned into various forms of vegetables, and with a flash all of them turned back to normal. "A changeling wouldn't waste the high amounts of magic to transmutate a pastry into a vegetable, not to mention doing so for fifteen pastries at the same time. Now that I think about it, I don't think it would even be possible for them." While Twilight pondered this new question, Mrs Cake placed a hoof on her chest and let out a sigh of relief.

Diane whistled. "Damn, you're good. Could you teach me some of those tricks?" She jabbed Twilights side with a hoof. Twilight simply gave her a deadpan stare, her expression was all that was needed to get the message across. "Come on Sparkle Butt, lighten up a bit. We're all friends here. No need to be so sour." Diane offered a friendly smile her way.

"Yeah! We couldn't have the princess of friendship being a party pooper on her new friend's welcome party!" Pinkie joined in by appearing behind the purple princess. It took a second before Twilight registered what she heard. "What? Sparkle Butt?"

"Eeyup." Diane simply answered as a small smirk spread on her lips. "So, do you all need something?" The sound of Mrs Cake's voice butted into the "tease Twilight timeTM".

Pinkie suddenly appeared behind Mrs Cake, the look of non-surprise on her face told that she was all too used to Pinkies antics already. "I'm going to be throwing a welcome to Ponyville party for Diane! There's going to be cake, cupcakes, mud cake and all kinds of different cakes! I just need time to prepare!" After announcing her grand plan for today she was gone in a flash, the only way to know that she ran off, instead of the freaky teleporting that she often does, was the sound of the door opening and the already fading hoof-steps coming from outside.

Suddenly Diane appeared behind Mrs Cake, the sight of somepony other than Pinkie suddenly appearing behind her slightly startled her. Even though Diane looked nearly identical to her new sister she somehow got a surprised reaction out of Mrs Cake. "So uhh, where do ya'll keep your booze? I think we might need it. For the party and stuff." Diane seemed to be inspecting her hoof casually, as if she didn't just brake the laws of physics like her sister does daily.

Mrs Cake gave a slightly confused look her way. "We don't have any alcohol here, but there is a store not too far-" She didn't even get to finish her sentence before Diane rushed out of the bakery just like Pinkie. The only thing that accompanied the pink blur trail that left was Diane's quick. "Thank you!"

Twilight's eyes followed the pink trail and her eyes narrowed. "I'm definitely going to get to the bottom of this."

Diane was happily trotting towards the store until she stopped in her tracks. She realised that she didn't wait for Mrs Cake to finish telling her where the shop exactly was. So she had just run off for no reason. "Well shit." Diane face hoofed but slightly miscalculated the swing and hit herself on the muzzle, she recoiled slightly from the pain and gently rubbed her muzzle. "Who knew hooves hurt?" Then her eyes narrowed in thought. "Wait, do I even need to buy booze? Can't I just make it appear out of my freaky pocket dimension hair?" Diane reached a hoof into her mane, half of her foreleg disappeared into the pink hair. After a little bit of rummaging around something caught her hoof, she then proceeded to pull it out.

"The hell is this?" What she was holding in her hoof was a small triangle necklace, she looked at it a bit closer and saw that the triangle had multiple horizontal lines on it which made it look like a pyramid. "Eh, I might or might not, need that later." Her hoof disappeared into her non-poofy hair once more as she placed the item back into her freakish pocket dimension.

"I wonder what else is in there." Diane took a quick look around herself and noted that she was in the middle of the Ponyville marketplace, perhaps not the best place to go around sticking your hoof into what basically was your wallet, and presenting whatever you pulled out to everypony. So she picked the obvious choice and decided to go to a more secluded area to check inventory.

"Mom, what is Pinkie doing?" A small filly asked her mother. They both saw Diane suddenly and very awkwardly stop as if she hit an invisible wall, pull something out of her mane, smack herself in the face, and she then turned around while whistling a tune. It was all very inconspicuous.

Diane whistled a tune while she trotted, it was from a metal song she had heard a few weeks ago that had become stuck in her head. Looking around she noted that quite a few ponies were looking her way. Her eyes slightly narrowed at why they would all be suddenly looking at her but then another thing caught her attention. The sound of an electric guitar being played echoed out in the surrounding area but Diane couldn't spot the guitar itself.

"Oh no." Diane's eyes widened in realization. "Please don't be a what I think it is."

As the guitar continued playing and the drums joined in, she realized what song it was going to be. The lyrics of the song almost threatened to be let out from her mouth, she was about to let out the biggest metal growl ever known to ponykind, but her own pink hoof stopped that as she forcefully stuck it in her mouth, the taste of dirt clung to her tongue and she spat the offending material out of her mouth. Near instantly both of the instruments fell silent, and the small crowd that had formed behind her started grumbling something that she couldn't quite catch while dispersing.

Diane wiped her forehead and sighed in relief. The rest of her trip of finding a quiet place to sit, was passed in silence. She didn't want to start another impromptu song number about the horrors of Earth's political climate. Diane shivered merely at the thought. After about ten minutes of walking she stopped at the outskirts of town, spotting a nice tree, she sat underneath it's shade and began taking inventory.

After a few more minutes, a wide variety of items laid in the dirt in front of her, some more questionable than others. "Let's see, I have a hockey mask that awfully resembles one that a fictional serial killer wore, a bottle of vodka, Jack Daniels, Jägermeister, a bottle of Applejack, a few unlabeled bottles of some dark liquid, an actual sword, the triangle necklace and about thirty bits. Wait, some of this stuff is straight from my apartment, or at least the alcohol and the mask are. Those were the bottles I was saving for Valentines day, and the mask was from the previous Halloween. Still, it doesn't explain the sword and the necklace." Diane looked over her items once more and frowned. "Oh, and I'm flat fucking broke, at least that's not anything new. Great, just absolutely peachy. I guess I could ask Pinkie if I could crash at her place. Or would I need to ask the Cakes for that?" She sighed and decided that she'd look for a place to crash at a later time, she had other plans for now.

With one quick motion of her forelegs all of the items in front of her disappeared into her mane, she wasn't sure how she was able to do that so quickly but she didn't question it. "The alcohol won't last forever though. I've got to make sure that it never comes to that, I don't think I can live without it." Diane stood up once more and headed back into town. The next location she was headed towards was the liquor store, or at least any store that sold any form of alcohol. She wouldn't buy anything, but it was always good to know where the closest shop selling alcohol was. As she entered the town once more she noted that many ponies were looking at her weirdly again. Diane trained her ears to try and hear any of the hushed whispers from the nearest ponies, and she was able to catch something.

"- might be having a bad day. Look at her mane, isn't it supposed to be poofy?" When the brown earth pony stallion saw that Diane was looking at him he abruptly went silent and gave her a nervous smile. The grey pegasus mare next to him did the same. This had given Diane an idea. She turned and started rigidly walking in their direction, when they both realised this, their bodies slightly stiffened and Diane flashed them a slightly crazed smile. She spoke in an emotionless voice, all the while enjoying the slightly on edge expressions of the two ponies. "Hello, do either of you know the closest shop that sells alcohol? I need to know where it is."

The brown earth pony cleared his throat and nervously answered. "It's right over there." He pointed his hoof past Diane to a building behind her. As Diane turned around a slight wave of embarrassment flooded over her, she wasn't exactly sure how she missed the store that had a giant sign above the entrance, which had an image of a bottle with a single letter X on the label. Diane then turned back to face the two ponies but saw that they were both running away from her. "What's their deal? I didn't even get the the fun part yet." Diane shrugged, she guessed that pranking ponies in this way might be a little too scary for them, for some mysterious reason. Her gaze then turned towards the liquor store, she might as well check out the store for anything worth buying in the future.

The store itself wasn't anything too out of the ordinary, it looked like one of those medieval taverns from the outside, but looked a bit too modern on the inside. There was many shelves full of alcohol all laid out on display.

Diane happily trotted towards the nearest shelf and began inspecting what they had in stock. The shelf mostly had weak alcohol products that didn't interest her so she went to a different shelf and inspected them instead. Her brow furrowed as she saw the alcohol percent of the nearest beverage. "Two point five percent? What kind of weak shit is this?" She muttered underneath her breath. She then quickly spun around and inspected every other shelf in the store, naming the highest alcoholic percent's of each shelf. "Two percent, five percent, five point two percent. What is this? What kind of shop am I in?" She started looking through each and every bottle, looking for anything above a ten percent but she didn't find anything. Eventually she gave up on searching through the shelves, she decided to ask the employee about this.

A pink hoof slammed on to the wooden counter, surprising the purple mare behind it. Diane's eyes quickly glanced at the mare's cutie mark, an image of grapes and a single strawberry rested on her flank. "Where's all the good stuff?" Diane leaned over the counter and narrowed her eyes.

"Pinkie? Never thought I'd see you here." Berry Punch offered her a pleasant smile. "I've got some good's still in stock. If you're interested." She then pulled out a dark bottle from behind the counter and showed it to her. Diane's eyes narrowed at the label. "Twelve percent? Don't you have anything higher?" Berry Punch's eyes widened in surprise. "Do you not know that alcohol over fifteen percent is banned?" This threw Diane for a loop. 'Banned? What?' Her thoughts echoed in her mind as she simply stared at Berry Punch for a few seconds before she turned around and left the store with a emotionless expression. Her face slowly turned into that of worry as she sat down outside the store. 'Alcohol over fifteen percent is banned? Curse you Celestia! I'd have to drink a hundred bottles of that weak stuff to even feel anything. Then again I could always create my own stuff, that would be pretty illegal though. I wonder what the punishment is for making your own moonshine.' Diane then shuddered as a memory surfaced in her mind. 'At least my first attempt won't end as badly as a certain idiot on the internet.' She would never look at chocolate milk and eggnog the same way again.

Diane shook her head to get rid of the image in her mind, she then turned towards the way she remembered Sugarcube Corner being, and she walked back. As the sight of the huge gingerbread house came into sight she wondered how long had she been outside, it couldn't have been more than half an hour. As she stepped inside the bakery the first thing she noticed was that it was completely pitch black. Before she could even say a word the lights were flicked on and a chorus of ponies yelled. "SURPRISE!"

Pinkie emerged from the crowd and made her way towards her. Diane noted that many of the ponies didn't seem to be phased at the exact copy of Pinkie Pie standing at the doorway, Diane chalked it up to Twilight already informing them of said magical anomaly before panic would spread.

"I thought it would take a little longer for you to get all of your supplies Pinkie, how did you do all this so fast?" Diane's eyebrow rose in a questioning manner, then again she should have expected something like this.

"I just went to get all my emergency party supplies from my hidden stash and told everypony on the way that there was going to be a party!" Pinkie skipped next to Diane and wrapped her foreleg around her back. She then inhaled deeply before shouting at the crowd. "Alright everypony! Let's get this party started!"

Before Diane could say a word she was dragged through the crowd of ponies into a makeshift dancefloor. "Hit the music!" Pinkie pointed at the white unicorn with a spiky blue hair that was standing behind a DJ booth. Accompanying the nod from the white unicorn, an electronic beat started playing from the surrounding sound systems.

Soon the big crowd of ponies dispersed, picking either the snack tables or the dance floor to mingle with the other guests. Diane however didn't have the time to pay any attention to them, she was currently in a fierce dancing competition with her sister, she wasn't sure how she was able to keep up with Pinkie, when she had only been a pony for about an hour and a half, nor was she ever a good dancer before her weird transformation. But these facts didn't seem to even pop up in Diane's head, as she simply tried to copy what Pinkie was doing.

Off to the side of the main party, a small group of ponies watched the two pink blurs dance in vivid ardour. Amongst them sat a befuddled alicorn princess, if she was being honest, she wasn't entirely sure if Diane really was Pinkies "new" sister, but the dance moves that she was currently pulling off with her sister spoke volumes to her credibility.

"I can't believe it, you really were telling the truth Twi." The magenta eyes of a cyan mare with rainbow coloured hair, followed the two pink ponies as they both danced in tandem with eachother, as if they had been rehearsing for this one moment for years.

An orange coloured earth pony with a blonde mane smugly stepped next to Rainbow Dash. "Ah'll take those twenty bits now Dash." The grumbling of Rainbow Dash was drowned out by the sound of somepony else in their group speaking up.

"Are you sure she isn't a changeling? I'm not doubting you Twilight, but this seems a little hard to believe." The voice dripped with lady-like elegance. "I could accept her being a mirror clone or even a changeling, but this?" The white mare shook her head, making her extremely well maintained curly hair slightly bounce side to side. "It seems... a bit much." Her blue eyes tracked Diane who was suddenly thrown into the air and caught by Pinkie once she came down.

"I'm sure. I did cast a complete scan spell on her, and it said that she is an exact true copy of Pinkie, it's as if she had cloned herself in her sleep, or somehow gone through mitosis. It doesn't make sense." Twilight's eyes didn't leave Diane, the purple pools tracked her every movement, looking for anything out of place. Eventually she sighed in defeat and rubbed her eyes. "It should be impossible, she should be impossible."

Rarity placed her foreleg around Twilight and pulled her into a side hug. "Relax darling, overthinking it will do you no good. I suggest letting it be for now. We have a party to enjoy after all, not to mention we haven't even officially met her yet."

"If she's anything like Pinkie then we have nothing to worry about." The quiet voice of a certain yellow pegasus joined into the conversation.

"You're both right." Twilight nodded her head in acknowledgement. "I think they might be done now, I see them walking our way." She pointed at the two pink ponies heading their way, one hopping towards them and the other simply walking.

"-much fun! Oh, there they are!" Pinkies voice broke through the electronic music and she waved at her five friends. The two merging groups greeted each other with hello's and some with hugs.

Pinkie then wrapped one of her forelegs around Diane's back, and pointed at each of her friends with the other. "Let me introduce you to my friends! That's Applejack, her family owns Sweet Apple Acres." She pointed at the orange stetson wearing mare. She tipped her hat at her. "Rarity, she owns carousel boutique and she can make really, really good clothes." The elegant white marshmallow gave a polite nod. "Rainbow Dash, the fastest flyer in Equestria." The multi-coloured hair was blown away from her eyes and she responded with a "Sup?" Then Pinkie pointed at the last member Diane hadn't met yet, who hid half of her face behind her pink hair. "And lastly Fluttershy! She's kind of shy but she'll warm up to you!" She then appeared behind her and pushed the shy mare towards Diane, the butter pegasus could only utter a near silent "Hello." Pinkie then turned around, facing Diane and pointed at her. "Girls, meet my new sister Diane, Isn't she just the best?"

"Haven't you only known her for an hour?" Twilight butted in. "Yeah! Imagine how great she is when we get to know her even more!" Pinkie replied with her usual excitement, Twilight simply face-hoofed, Diane noted that she didn't hit herself in the muzzle, it could be that Twilight has had years of practise at face-hoofing.

"Ooh! This is a great song! Come on, lets go dance some more!" Pinkie pulled Diane back to the dance floor before she could interact more with the rest of the mane six. This was how most of the party went, Diane was dragged to all kinds of different party games and dances by Pinkie. It only seemed to stop after about two hours, when a part of the party guests had to leave, and Pinkie had went to say bye to everypony leaving. The ponies who left were mostly all the foals and their parents. Seeing the last of the younger guests leave Diane had an idea, she could properly bring in some influence from Earth to this party. In other words, the very last bottles of alcohol from Earth.

"Should I really spend the last of my alcohol on this?" Diane pondered while she held a bottle of Jägermeister in one hoof, eventually after the very long deliberation of ten seconds, she shrugged and approached the mane six, minus Pinkie who was somehow back on the dance floor. The group was near the snack tables, eating a few baked goods. "Hey girls, how about we kick this party up a little? I hope you none of you have anything planned for tomorrow." She pushed the bottle towards them, it slid on the table until it clinked with the punch bowl.

And the rest of the night was an incomprehensible blur that none of them would remember. Some parts for good and some for bad reasons.
