"Hey, look," Spike shouted, "Applejack's here!"
Twilight gasped. "I got it! No pony can herd like Applejack."
"Yeah! We can drive 'em back into the forest." Rainbow did a little loop in the air.
Applejack shook her head. "I'll rastle 'em up, but I need everypony's help to do it. Twilight, you and Rarity wait over there. I'll herd the little critters straight at ya like a funnel. Rainbow Dash, you and Fluttershy stay on top of 'em, don't let 'em fly away."
All five ponies jumped into action, rounding up all the parasprites into one giant ball.
"Okay, is that all of 'em?" Applejack asked.
"Nope! Hold on!" Spike came running out of Fluttershy's cottage, with one last parasprite clutched in his hand. He jumped up and shoved it into the ball with the rest of them.
"Alright y'all, here goes nothin'." At Applejack's word, they began rolling it into the forest. A few tried to get loose, but were expertly herded back in.
Finally, the huge wad of parasprites vanished into the Everfree Forest.
"There, done." Rarity said, wiping her brow. "I do hope that all was worth it."
Twilight started walking back into town. "That's just half of it. Now we need to clean up the damage they caused before the Princess arrives."
On the way back, they met Pinkie Pie. "Okay, girls," she said, "I've got almost all the instruments we'll need to get rid of those parasprites."
"Way ahead of ya." Applejack laughed.
Rainbow landed next to her. "Yeah, we already herded 'em back into the Forest."
Pinkie sank a little. "Oh."
"But, there is one thing you could do," Twilight said, nudging her. "We've still got a royal party to prepare for."
Pinkie reinflated instantly. "There's not a moment to lose!"
Twilight laughed. "That's the spirit!"
