This story is based off the events from the episode, "Look Before you Sleep."

After the unexpected but fun sleepover at Twilight's library Applejack starts secretly wearing a frilly dress that Rarity dared her to wear during the slumber party. But what she didn't realize was that the dress was enchanted making her think she's a five year old filly.

Now Big Macintosh and Twilight Sparkle will have to work together to help Applejack remove the dress; or risk seeing the rustic farm mare's mind turn into that of an adorable little filly.
