"Uuuuuhhh. I don't feel too good." stated a sick Rainbow Dash. "Better call Twilight, she'll know why I feel so bad today..."
Rainbow hoof-dialed both Twilight and Fluttershy, because Fluttershy could help her too.
"We're here, Rainbow!" exclaimed Twilight, busting into Rainbow's bedroom with saddlebags full of Celestia-Knows-What. After a quite strange examination, Twilight declared she had "Hasbro's Disease", an illness so serious that if left untreated could turn her into a lifeless, hard-as-stone, doll!
"But who will take my place in the "Fallen Cloud" show next week?" questioned Rainbow. "I NEED to be there, or else-"
"I-I'll replace you, if you don't mind." stuttered Fluttershy. "Rarity can make me look like a Wonderbolt for you."
"That's the BEST IDEA EVEEEER!" shouted Rainbow Dash. "But I don't feel too good..."
"BLEEAAAAUUGGH!"
"Yes, I will go to Rarity's right away!" said Fluttershy as she raced off.
Fluttershy walked into Rarity's boutique, humming softly.
"Fluttershy, what brings you here today?" asked Rarity as she added a trim of lace to a dress.
"I-I need a W-wonderbolts suit and a manecut, please..." stuttered Fluttershy.
"You're in luck, I have this old suit from when Rainbow was first an official Wonderbolt, it will definitely fit you!" exclaimed Rarity as she levitated a Wonderbolt suit over to Fluttershy. "What about the manecut, Fluttershy?"
"Um, I'm replacing Rainbow in her Wonderbolt shows, so I guess wonderbolt-like?" the Pegasus replied. "Rainbow is seriously sick..."
"Oh, I am greatly sorry to hear that." Rarity said as she levitated some scissors over to Fluttershy. She gently helped Fluttershy into a chair and put a cape on her.
