Pinkie Pie awoke with a jolt. Something felt... off. She couldn't put a hoof on it, but she knew that there was something different. She continued about her morning, completely ignoring the fact that she now had both a horn and wings.
"Why, good morning, Pinki-" Mrs. Cake began before noticing the obviously pink horn and wings that accompanied the mare.
"Whaddaya staring at?" Pinkie cheerfully asked, turning to follow Mrs. Cake's line of sight. Then, she saw the wings.
"Ooh! Yay! I can fly now! Just like how I imagined, too!" She squealed, flipping head over hoof.
Mrs. Cake warily eyed the pink alicorn as she hovered about the room, upside-down.
"Pinkie, you're... an alicorn."
Pinkie shrugged. "So?" She replied as she continued hovering.
"So... you're practically a goddess now."
Pinkie shrugged again. "So? Why am I an alicorn, anyways? I'm fine just how I am..."
"I believe I can answer that," Celestia added as she walked into the room.
"Really?!" Pinkie replied, bumping into Celestia with her tail, "That'll be great!"
"But don't forget, Pinkie, with great power comes great responsi--"
Pinkie took off in a blazing ball of pink fuzz. She proceeded to do an upside-down backwards triple rainboom as she left the building through an open window. Soaring through the light clouds, Pinkie couldn't help but shape a few of them... or all of them, into various inane shapes and patterns. By the time she was finished, she had carefully sculpted the entirety of Ponyville using nothing but clouds.
And then she sneezed.
All at once, the clouds scattered, and not only that, but as she had been an Earth Pony just a day ago, she had absolutely no control over her newfound magical abilities. A blinding bolt of energy shot from her horn, creating a rift in the space-time continuum. From said rift fell an earth pony, of whom looked very much like Rainbow Dash... except she was Rainbow Dash, but from a different time.
In fact, said Rainbow Dash was from an entirely different evolutionary period of ponies. Her mane was much clumpier, and her muzzle was... weird.
Pinkie gasped, and immediately dove after the shocked mare that had fallen from the portal.
"GOTCHA!" She yelled as she caught hold of the pony.
A crowd had gathered in Ponyville's town square from all the commotion. Rainbow Dash, at least, the pegasus one, sped up to the pink alicorn.
"Pinkie!" She exclaimed, pointing at the now unconscious mare in the alicorn's grasp, "What is that thing?!"
"NEANDERTHAL!"Twilight exclaimed the moment her eyes caught a glimpse of the pony.
"Calm yourself, Twilight," Celestia said softly as she landed beside the Princess of Friendship, "This may be quite a... strange event we'll be witnessing..."
Pinkie set the rainbow-maned earth pony on the ground. The mare's chest rose and fell softly to the rhythm of her gentle breathing. Suddenly, she jerked her eyes open.
"W-where am I?!" She suddenly yelled, startling everypony watching. Her eyes nervously darted about, taking in the unfamiliar form of the modern pony. "Who are you?" she followed, slowly backing from the mass of the crowd.
"I'm Pinkie Pie!" Pinkie hollered as she hovering gently, her tail flopping over her face.
"...Pinkie Pie?" The strange pony questioned, warily eyeing Pinkie, "Do I know you... darling?"
"What, do you think you're Rarity or something?" Rainbow asked, raising a brow as she trotted closer to the mare, "I mean, you've got the accent and all, but..."
"That thing is most certainly not me!" Rarity angrily replied, stomping up behind Rainbow.
"Wait, wait, wait..." The pony suddenly blurted, waving her hooves in front of her, "So, this pony here with wings and a horn's Pinkie Pie?!"
Celestia stepped up from the crowd.
"Well, yes," Celestia replied, her towering form looming over the now-cowering earth pony, "You did not know?"
The pony shrugged.
"The Pinkie Pie I know isn't so... hyperactive, nor is her mane darker than her coat..."
"You mean this Pinkie Pie?!" Pinkie exclaimed, pulling her ancestor from another rift in time.
"...Yes, darling, that Pinkie Pie."
"Hey, I, uh... never really caught your name back there," Rainbow said as she shuffled past Rarity towards the strange mare.
"I'm Rainbow Dash, darling. I care quite a bit about my fashion choices. In fact, this... Rarity that you speak of, does she too have a strong taste for fashion?"
Rainbow Dash-- the pegasus one, mind you-- stared at her counterpart with a deadpan glare.
"Are you bucking kidding me?"
"Now now, darling, we mustn't be uttering such words, and in fact, you actually look quite similar to myself."
"ARGH!" Rainbow screamed, flying off, "PLEASE TELL ME I'M NOT RELATED TO THAT BUCKIN' PONY!"
The alicorn Pinkie Pie snatched a notepad from her mane, and a pencil from her ancestor's mane. She quickly scribbled down several notes, deep in thought, until her head popped up at breakneck speed.
"You are, Rainbow! She's your great-great-great-great-great-great-great-great-great-great-great-great-great grandmother on your mom's side!"
"Wha-- how..." Twilight began muttering as she grabbed the notepad from Pinkie's hooves, "SINCE WHEN DID YOU KNOW HOW TO TRACE ANCESTRAL TRAITS USING NOTHING BUT STRAIGHT-UP OBSERVATIONS?!"
"I didn't! Pinkie replied, her grin beaming brightly, "I just left a clone of myself to do that while I double checked it's work by traveling through time!"
Rainbow Dash's great-great-great-great-great-great-great-great-great-great-great-great-great grandmother grimaced as her mind failed on several levels to process just the concept of time travel.
"And now, let's bring you back before we start a bigger paradox than what I've been looking at!"
In a blinding flash of light, the ancestors of Rainbow Dash and Pinkie Pie were gone.
Hi!
OH GOD, PINKIE, JUST STOP BREAKING INTO MY STOR--
