"Twilight! Help us!" Apple Bloom panted, as she and the other girls busted into Twilight's library.
"What's happen to you all?" Spike asked. He screamed. "What - wha - Seriously though, that's cool. Hey, Twi! Twilight! Come check this out!"
The lavender unicorn groaned, rolling her eyes, "What is it this time?"
Spike pointed fearfully at the three former fillies.
"Oh Celestia! What has happened to you?" Twilight asked, horrified. Almost at once, she calmed down. "Oh, Spike. You're silly. It's probably just a game. Humans don't exist."
"We didn't think so either," Sweetie Belle confessed. "I think we DID drink that potion at Zecora's..."
"You WHAT?" Spike asked, nearly fainting.
"It doesn't matter," Scootaloo groaned. She glided to Twilight's side. "You have to help us!"
"I - I don't think I can," Twilight muttered. "SPIKE!!! Where's that Supernatural book again?"
Spike fetched the book, the number one assistant he was.
Twilight snatched it off, without meaning to. Of course, in emergencies, no one cares to say Thank You or Please. And this was a REAL emergency.
"Humans..." she whispered to herself, scanning through the book, with shifty eyes. "It doesn't say anything about humans, Spike!"
Spike looked desperately around. "I don't know, Twi," he said.
"We need to tell the Princess," Twilight cried out. "Come on, let's go, girls."
The small company of five left the library at once, the girls carefully wrapped up, so nopony knew of the horrifying event.

Pinkie Pie bounced her way to Twilight's library, hoping to borrow a book from her unicorn friend. It was a lovely sunny morning, and the breeze felt cooler than a bath on a hot day, and Pinkie Pie loved it when it blew against her mane. She also loved the happy atmosphere - it did make her smile more than ever.
Unexpectedly, she bumped into Twilight and Spike, who were frantically trying to rush towards Canterlot, whilst acting all normal, and as if everything were okay. Of course, the three unidentified objects floating beside them caught Pinkie Pie's attention.
"Hi Twilight!" she cried out. "Nice day, huh?"
Twilight rolled her eyes and groaned, "Yeah..nice."
"Ooh! What's those things hanging around your head?" the pink earth pony asked, eyes wide and curious.
Twilight was tempted to snap at her friend, harshly. But instead, she just said, "I'm sorry, Pinkie. We really need to go!"
"Okie Dokie Lokie!" Pinkie Pie giggled. "I'll come with you!"
"Uh..." Twilight said. She lost her temper, which was badly excited, "Pinkie! I'm busy! This is serious!"
"Awww...I'll keep my lips sealed, then!" Pinkie Pie announced. "Hey, what are these things?"
She lightly pushed the hood off Apple Bloom's head. She squealed, "Aaah!!! It's a - a -" She turned to Twilight, and cocked her head sideways, in confusion. "What is it, Twilight?"
"Oh..uh..." Twilight mumbled, behind her teeth.
"And look! There's more!" Pinkie Pie cried out. She playfully pushed the hoods of all the three mysterious things. "This one looks like Sweetie Belle! This looks like Apple Bloom! And look - Scootaloo!"
Spike couldn't help but shriek, "It IS them! They've been turned into humans!"
"These aren't humans, Spike," Twilight scolded. "I told you not to tell anypony. That goes for you too, Pinkie."
"Scootaloo, Apple Bloom and Sweetie Belle are humans!!!" Pinkie Pie screamed. "RUN! Run for the hills!"
The other ponies stared in horror at the the Powerpuff Ponies.
Some screamed, some ran around, and some dashed into their houses.
"Celestia preserve us!" somepony shrieked, as she locked her doors and windows.
Twilight glared at Pinkie Pie. "Ponies! Do not panic! I'm about to ask Celestia about this. It's nothing, really."
She grabbed the CMC, Spike and ran as fast as her hooves could carry her, hooves metaphorically flying.

"What do you think, Princess?" Twilight asked. "Is it something serious?"
"According to this book," the Princess said. "It must be a serious case of hay fever."
"But hay fever is --" Twilight protested.
"In the human world, yes," Celestia said. "But in Equestria, hay fever "
"We drank a potion," Apple Bloom answered. "If Ah can remember properly, Ah think it was made of Sugar, Spice, and Everything Nice."
"Alas, that, I cannot explain," Celestia whispered.
"Is there a cure?" Sweetie Belle asked, her eyes hopefully looking up to the majestic alicorn.
Celestia shook her head slowly. "We are talking about mysterious allergies, my filly. I know not. But this is a threat! Twilight, warn everypony. We must find the source of this, and eliminate it before others catch it!" she ordered.
Twilight nodded, "Yes, Princess! Rainbow Dash! Pinkie Pie! Fluttershy! Rarity! AppleJack! We must stop hay fever from affecting us all!"
"Uh..Twi? Ah think we'd better hurry, then," Apple Bloom pointed out. "We're not the only ones contracting it."
Twilight held her breath, as she turned to look at where Apple Bloom was pointing. Why, there floated three more Powerpuff Ponies - Lyra, Gilda (even if she was a griffon), and not surprisingly, Derpy Hooves.
