New Equestria

Twilight Sparkle paced in her room, her wings fluttering at her sides anxiously. Books flew from the shelves in her magical grasp as she frantically searched through them, trying to find something, anything, some shred of a possible answer must be somewhere in-

"Twilight? What's going on? Rarity said you were really upset about something." Spike said, walking into his old home with his usual Twilight Panic Attack kit of cookies, a paper bag, and pillows. Twilight didn't so much as glance at him as she raced through the shelves.

"My sister just became a princess, Spike!" she called out from three rows over in the forbidden magic section as several books crashed to the floor. Spike set the supplies on the nearby table and tried to follow her through the library, in case she hurt herself by accident.

"Isn't that good news?" he asked, wondering what her problem was. Twilight suddenly teleported in front of him, causing him to nearly collide with her.

"NO!!! It makes no sense! She can't rule over her studies, much less Equestria!!" she practically screamed, the wind force from her shout causing him to fall on his butt. Spike glared up at her, disappointed in her narrow-minded view of her own sister.

"Hey, Magic may have autism, but that doesn't make her stupid, Twilight!" he snapped back. Twilight's eyes widened in shock as her wings shot open.

"Oh, nonono!!! I wasn't saying that, Spike! It's not that she's dumb, it's that she hasn't been trying! It took me almost my entire life up until recently studying magical sciences, and that's how I became a princess. I earned my title, Spike. She wasn't doing anything special! Wings just farted out of her back for no reason!" Twilight shook where she stood as she wondered how on earth her 'special' sister could have accomplished something like this. Spike rolled his eyes.

"Maybe she had an epiphany that will change the course of history or something. I don't know. Why don't you go ask her yourself, Twilight?" he asked. Twilight's eyes twinkled as she realized what a good idea that was.

"Spike, that's brilliant! Maybe she just needs help bringing her vision into reality!" she exclaimed, grabbing her research tools. Spike sighed, eating one of the cookies he had brought. Twilight meant well, but she tended to underestimate the capabilities of her little sister due to her mental disability. Twilight grabbed her last roll of parchment before turning back to Spike.

"Hey, make sure to tell my assistant to pick all of those up, OK?" she asked, pointing to the books before teleporting away. Her red-haired assistant peeked around the corner upon hearing this, her pink hair bow seeming to droop in frustration as she saw the mess Twilight had left again.

"Perfect!" Princess Magic proclaimed as she finished her newest creation, wiping it clean with a nearby cloth. She dropped it into her fluffy purple fur as a nearby loud sound startled her. She turned around, seeing her sister standing behind her, panting slightly from her previous gathering frenzy.

"Oh, hi sis! How are you?" she asked, turning back to her creations as she made sure they had all the proper pieces. Twilight smiled at her sister.

"Oh, I'm fine, I-"

"I'm a princess now!" Magic interrupted. "Just like you!" Twilight brushed it off, knowing it was just a side effect of her sister's mental condition.

"Yes, that's right, Magic, you are a princess now." Twilight said, a slightly patronizing tone in her voice. Magic tried to ignore it, knowing her big sister just didn't know better and thought she needed coddling.

"so what are you.... Doing?" Twilight asked as she looked up, her face paling in horror as she saw a room full of what looked like dull beige ponies with mild elephantiasis, with a few red and purple ones mixed in. Magic bounced in place, giggling.

"They're potatoes!" she exclaimed happily.

"They're WHAT?" Twilight burst out in shock. Magic hovered up next to the face of one of them, her little wings letting out a muffled buzz under her copious amounts of fur.

"They're ponies made of potatoes! That's how I became a princess! I was playing with my pet potato the other day in the park, and someone said he wasn't a real pet because he can't move, so I thought to myself, 'Well, what if he could?', so I thought about it, and then realized it was possible if I altered one of your transmutation spells a little by combining it with your charm that makes plants grow! Now I can turn potatoes into ponies!" she explained, patting the face of the one she was hovering next to with a giggle. "For example, this one is a russet potato. He's very strong, isn't he?" she crooned as she poked his bicep, eliciting a blush from him. Meanwhile, Twilight was trying to process the information in front of her. Her little sister, the one who had to go to special schools for the mentally challenged her entire life, the one who was literally obsessed with potatoes and knew everything about them, had created a new race of pony from the starchy tubers and was now literally flirting with a potato. She realized now that her sister had become a princess because she was meant to rule the new kingdom that would inevitably be made for these unusual ponies. She didn't know where it would be, how it would interact with Equestria, or how on earth her sister would run the place, but she did know one thing.

"This is definitely the weirdest thing that I've walked in on you doing."
