"Well how are we meant to get our colours back?" Rainbow asked. "We can't stay like this forever! Cadence stole my awesome colours and I need them back! I can't stay in Rarity's colours forever! They're waaay not cool!"
"Excuse me!" Rarity exclaimed, clearly offended. "Sure, my colouring may be different to yours, but there is NO need to be rude! RAINBOW DASH GET YOUR HOOF AWAY FROM YOUR MOUTH THIS INSTANT YOU LITTLE..."
"Girls, I don't think..." Fluttershy trailed off.
"WELL EXCUSE ME, MISS HYPOCRITE! I GUESS SWEARING DOESN'T COUNT AS RUDE, DOES IT!?! ALL I'M SAYING IS THAT YOUR COLOURS ARE WAAAY TO GIRLY!"
"AND I SUPPOSE RAINBOWS AREN'T GIRLY THEN, ARE THEY?!?"
"NOT WHEN THEY'RE AS AWESOME AS MINE!"

The two argued for several minutes as the others drew more and more bored. Except Fluttershy, who, at each insult, tensed up more and more. After 5 straight minutes of of arguing, Fluttershy finally cracked.
"GIRLS! CAN YOU TWO PLEASE STOP ARGUING SO WE CAN ACTUALLY START WORKING ON SOLVING THE PROBLEM AT HOOF!?!"
Her hooves flew to her mouth.
"I'm sorry..." She whispered.
Everypony looked round, surprised, Fluttershy never lost her temper. Unless, of course, you counted the incidences at the gala and with Iron Will. There was silence for several seconds.

Cadence finally decided to break the awkward silence. "Rainbow has a point. How are we meant to get our correct colours back?"
"Not tah mention the colour of the rest o' Equestria." Applejack added. Pinkie had an idea.
"Hey! I have an idea!" She started. "This seems a lot like Discord's kind of magic, maybe he could change us back!"
"That... That's actually a rather fair point..." Said Twilight, who was obviously surprised. Discord snapped his claw, hoping for the best. There was a bright white flash, but nothing happened. They all sighed in disappointment.
"Well," he sighed. "It was worth a try."

"Oh, come ON!" Twilight exclaimed. "There's GOT to be a book for this in here SOMEWHERE!" The 10 ponies and 1 draconequus were in the Canterlot archives, looking for something to help with their situation. They had been studying there for almost 2 hours, looking through books and scrolls, trying to find something, ANYTHING to get things back to normal. Discord wasn't helping. He had turned every book they had found useless into some kind of book monster that reminded Twilight of a thing in Harry Trotter and the Prisoner of Tartarus called "The Monster book of Monsters" and they kept biting the ponies and flying round the room distracting them. Pinkie had already given up and was bouncing around the place trying to catch the floating books, just causing more of a distraction.

"Discord, Pinkie, could y'all maybe go outside and play in some chocolate rain or sumthin'?" Applejack asked.
"I believe you'll find that there's hardly a cotton candy cloud in the sky!" Discord replied casually.
"Then why not whip some up?" Rainbow asked.
"Why not?" He replied, sounding defeated, yet he was still smiling.
"And speaking of whipping," Pinkie said as they walked outside. "Could you make whipped cream too?"

Soon the castle labyrinth hedges had been turned to whipped cream, cotton candy clouds were raining chocolate overhead, and in the middle there was a life-sized chocolate fountain made of peppermints.
