Fluttershy waved goodbye to Rarity as she and Pinkie got into the van and headed back home.
Suddenly, there was a loud scream that echoed through the air, the ground shaking slightly as it did so.
"What was that?" Pinkie asked, looking in the mirror behind her to try and see what it was.
"It sounded like Rarity!" Fluttershy said, looking worried. "Perhaps we should head back and look."
"I'll pull up and we can walk back!" Pinkie said. "It'll take longer to drive. That, and I can't turn us around in a one way street!"
Pinkie drove into a nearby parking space and cut the engine, then both she and Fluttershy hopped out and made their way back through the streets. Something odd was happening. Golden and Blue specks of energy floated in the air, interfering with the street lamps and causing the entire environment to glow slightly.
It was rather reminiscent of ash particles from a forest fire, and Fluttershy was about to remark on this when suddenly two larger orbs approached them.
"Ooh! Pretty!" Pinkie said. Seconds later, the two orbs slammed into them, and everything suddenly went very bright.
Fluttershy covered her eyes to try and protect them from the intense light, and only removed it once the light had faded from view. She looked about to see that the sky was still full of those sparks dancing about, which looked very surreal in the light.
Something brushing against her legs suddenly got her attention, and she quickly looked down to try and see what it was. Wait a second. The skirt of her dress seemed to be longer than normal. But that wasn't possible, right?
She quickly blinked to see if this was actually happening. One moment it seemed as if her eyes were just playing tricks on her. Then, with a slight grumble and a brief stretching sound, her skirt began to grow longer.
As it continued to grow longer, the hem suddenly started to sink into the skirt as it reached her ankles, where it stopped growing longer. The turquoise trim and pattern vanished as the entire skirt turned yellow, followed by the butterfly patterns in the skirt vanishing.
Another skirt flowed down Fluttershy's legs on the inside of the other one, providing a bit more volume to it, whilst her bodice suddenly started to shift. The side straps around her arms began to grow up her arms and shoulders, getting wider whilst completely obscuring the pink straps at the top, whilst her neckline dropped slightly and formed curve, the lighter colored frills vanishing into the fabric as the entire bodice turned dark blue.
The rear of the bodice then grew taller, followed by a white collar emerging from the back and growing upwards until it was in line with the base of her skull. Parts of the freshly expanded sleeves then suddenly got pulled inwards.
Fluttershy felt she recognized this dress, but finally got the key clue when her sandals, which she could clearly see, morphed into golden heels, the pink fabric around her legs morphing into golden bows on the heels. This also had the effect of increasing her height a little. Her sleeves suddenly began to inflate like balloons, growing until they were quite puffy in size. They also gained red infill as the process seemed to come to an end.
Fluttershy was more confused than scared. "Why am I Snow White?" She turned to suddenly see Pinkie Pie, and gasped. "Oh my goodness! Pinkie, what happened to you?"
Pinkie's grin was akin to the Cheshire Cat. "Welllllllllllllllllllllllll..."
Meanwhile...
Pinkie had begun to feel a bit weird after the energy had hit them, and had ducked round the other side of the van to get some of her secret supplies out. Precisely what these were nobody knew, but then again you had to accept that, sometimes, Pinkie Pie was just Pinkie Pie.
Pinkie went round the side of the van to the door, when something in the door mirror caught her attention. She stopped and looked closely, suddenly noticing there was a red tiara on her head. "Oooh! Pretty!"
As she stepped closer, she saw her tank top suddenly sprout sleeves, which turned pink and gradually grew longer and longer, until they reached her wrists. Purple fabric popped out of the ends as white gloves materialised on her hands, followed by the sleeves becoming embedded with many, many crystals.
The emblem of three balloons vanished from her shirt, as it was now, and the material softened as it turned the same shade of pink as the sleeves. The same, however, was not true of the center of the shirt, which turned a darker pink and was covered in white buttons. A collar also grew out of the shirt and suddenly burst backwards, neatly shielding the back of her neck from unwanted sunlight.
"Hey! I look really weird! I LOVE IT!"
Another part of her shirt pushed up to form a choker around her neck, before her skirt suddenly merged into her shirt, leaving her in a dress. Her sandals began to drop in height as they morphed into a pair of pink heels, and her socks soon vanished with them.
The skirt began to merge together, the three tiered ruffles turning to a smooth, flat surface. It rather reminded Pinkie of when she adopted her sad persona. Then everything happened at once.
With a loud bang of a party popper, her skirt shot downwards, over her knees and growing to completely cover her feet in seconds. With another pop, it then exploded outwards, covering a surface area of several feet in less than two seconds. The inner layer turned a deep purple, with lighter purple segments erupting out of the top of the skirt on each side, and a white thing appearing around her waist.
The suddenness of the changes caught her slightly off guard, but Pinkie quickly recovered. "YAY! I LOVE THIS! YOU'RE NOT THE ONLY PRINCESS, TWILIGHT!"
She then went round the other side of the van to see Fluttershy's clothes had also changed, and she seemed similarly surprised.
Now...
"I wonder what caused this," Fluttershy mused to herself, observing the constant movement of the sparks in the sky. "That doesn't normally happen."
"I'm willing to bet Equestrian magic," Pinkie said, moving slightly slower than normal thanks to her dress. "That seems to cause everything around here!"
"And without Sunset here, we can't easily get a message to Princess Twilight," Fluttershy noted. "We need to check our friends are OK."
"Not with the van, we aren't," Pinkie said. "You're not insured on it, and I can't exactly drive with this on!"
"I think we should split up," Fluttershy said finally. "You go check on Applejack, and I'll see if I can find anybody else!"
"SURE THING BYE!" Pinkie shouted. Both girls set off in opposite directions, one walking, and the other using exploding sprinkles to propel herself along.
