Harmonic Vengeance

Shoulders back. Stand tall. Project confidence. You've got this.

"Don't worry, everypony!" Bruce Banner called. "I have a plan. Rainbow Dash, can you bust those pink clouds like normal ones?"

"One second." She flashed off in a burst of speed, and just as quickly was back, looking a little stickier and pinker than before. "No. No you cannot."

"All right. Good to know. Can you herd them all together, into a big clump?"

"One second again." Zoom. A pause. Zoom. "Yes you can."

"Great. Do that." Zoom. No return zoom. "Applejack, once they're gathered, lasso them down to earth."

"Pegasi only touch clouds through magic. I don't think my lasso will--wait a second. Cotton candy. Right."

"Cotton candy?"

"That's what the clouds are." She pulled a variety of ropes out of her saddlebag and started tying them together, trying to make a lasso long enough to reach the sky.

"Figures. Fluttershy- what happened?"

"They ate the apples and now they're deer things."

Recalculating.

"Is cotton candy edible for animals?"

"Before things went insane, certainly not. Now? Who knows?"

Bruce tapped his hoof on his chin. "Applejack?"

"Yesh?" Her speech was muffled by the rope in her mouth. Her lasso was incredibly long by now.

"Do you want to sell all that popcorn, or just get rid of it?"

She spat out her rope. "Little dirty to eat now."

"For humans. Fluttershy?"

"Yes, they can clean that up."

Rainbow Dash returned, panting. The clouds had gathered into a lump, and were too sticky to separate themselves again. "I don't want those clouds to get loose again. We need to find a way to get rid of them permanently."

Bruce could've sworn a physical lightbulb appeared over his head. "Pinkie Pie!"

She stopped circling the grounds and stood at attention. "Yes, Twilight?"

"How many recipes do you have that involve cotton candy?"

She paused. Bruce had half-expected her to shout out a random figure like "537!", but instead she merely said, "I have many. Why?"

"We need to dispose of this." He waved a hoof at the massive load of cotton candy Applejack was tugging down to earth. "Can we count on you?"

She nodded. "I shall take this over to Sugarcube Corner." She took the rope from Applejack and led the cloud away. It was still floating a little above the ground.

"She seem weird to anyone else?" he asked.

"Darling, this is Pinkie Pie we're talking about," Rarity said. "She's always weird."

"True. Rarity, can you use that spell for resizing dresses on those apples?"

She pondered. "I can certainly try." Bruce accompanied her to the trees; it would be more efficient if both of them could cast it at once. Twilight (and therefore Bruce) was magically sensitive enough to pick up the spell as Rarity began to cast it, and soon they were both working, struggling to force an apple to shrink.

"This... is the most powerful... magic... I've ever... fought!" Bruce groaned, as the apple shrank slowly and reluctantly. Sweat was pouring down both of them. Rarity barely even noticed. She, too, was panting and grunting.

"Darling... I'm really... not sure this will..."

SPROING.

The apple rebounded against their spell, growing even larger than before. Both of them felt it snapping against them, like a rubber band stretched too tightly; Rarity put a hoof to her head. Bruce felt the headache from the backlash too.

She sighed and turned to Applejack. "I'm sorry."

"Don't be. Ya helped loads with everythin' else. The apples'll keep until we can find another solution."

Spike ran up, holding a letter in his claws. "Twilight! This just came in from the princess."

Bruce picked it up. The magic of telekinesis felt really cool, actually. He skimmed the letter swiftly. "The princess needs us in Canterlot. Doesn't say why. Good thing we're all right here--no, not Pinkie, we'll have to pick her up. Anybody know the train schedule?"

Rainbow raised a hoof. "Used to live by the tracks. It was really noisy, but the upside is I've memorized the schedule. Unless they changed it, there's a train for Canterlot in about five minutes. We can be there in half an hour, it's so close."

Bruce nodded. "Great. Let's go!"
