None of the ponies spotted Fluttershy and Rainbow Dash as they flew high in the sky towards Twilight's house/library.

"Okay, here's what we're going to," Rainbow Dash said. "We're going to drop down right in front of the door, quickly open it, and run inside. Got that Fluttershy?" Rainbow Dash looked over to Fluttershy. Fluttershy nodded her head.

"Okay, on three. One….." Rainbow started. "Two…. THREE!" Both pegasi raced toward the door. Rainbow burst through the door, Fluttershy close behind. Rainbow Dash quickly turned around and closed the door.

"Twilight!" Rainbow shouted, looking around.

"Yes, Rainbow Dash?" Twilight said, coming down the stairs. Taking one look at Rainbow and Fluttershy she said, "Oh sweet Celestia, what happened to you two?!"

"Um, well, I uh," Fluttershy said shakily. "I, uh, kinda turned Rainbow into a bat last night, and normally they would die when I bit them but, um, I guess that didn't happen with Rainbow. And now we look even more like bats then before." Fluttershy looked at Twilight, hiding most of her face behind her mane.

"But, how are you a bat in the first place?" Twilight asked, confused.

"Well, um, remember when I had turned into one? Well, I guess it never really went away, so every night I turn into a bat. But sometimes I bite ponies and they usually die or become very injured. But that didn't happen with Rainbow for some reason." Fluttershy snuck a peek and Rainbow Dash before continuing. "And I guess now, the effects are becoming more permanent. We weren't sure what to do, so we came here."

"Yeah," Rainbow said. "But this is pretty cool. I mean, we have bat wings, fangs, and are cutie marks have bats!"

"I'll see if there's a spell I can use to change you back," Twilight said as she started going through her books. "Spike!" Twilight called. "I need your help!"

Spike came down the stairs. "Yes Twili-" He stopped when he saw the two pegasi. "AHHHH! TWILIGHT! WHAT ARE THOSE THINGS!?" Spike screamed, pointing at Rainbow Dash and Fluttershy.

"Calm down Spike. It's just me and Fluttershy," Rainbow said, slightly laughing. "We've just, uh, changed!"

"Spike, I need you to help me find a spell that can change these two back," Twilight said, ignoring that fact that he screamed.

"Okay," Spike said, then started looking through books opposite of Twilight.

After a few hours of looking through books, Twilight hadn't found any spells that could help Rainbow and Fluttershy.

"I'm sorry guys, but there just isn't anyway to change you back," Twilight said, exhausted from looking through all the books.

"Oh, um, are you sure there isn't a spell to make me not bite other ponies? Or at least have control of myself around them?" Fluttershy asked, starting to get worried that she would kill more ponies.

"Well, there is this one spell that might work…" Twilight looked a little uneasy. "But I've never used it on another pony before. I haven't even tried it on anything." She looked over at Fluttershy. "I'm sorry Fluttershy. I wish I could help you."

"Don't worry Fluttershy," Rainbow Dash said, nudging Fluttershy. "I'll make sure you don't harm any more ponies." Rainbow looked over at Twilight. "But Twilight, how exactly are we going to hid our wings and cutie marks? I mean, they clearly are different."

"Maybe we can go over to Rarity's and she can help cover them up." Twilight started for the door.

"Oh, but, um, what about the fangs. Do think anyone will look at them?" Fluttershy was about to say more, but Twilight interrupted her.

"As long as you keep your mouth closed, you'll be fine. And besides, not many ponies are out today." As Twilight opened her door, she saw a huge crowed of ponies going from her house to Rarity's. "Maybe this will be harder than I thought," Twilight said out loud to herself.
