Twilight thought she'd had enough excitement for one day after meeting her human counterpart. Or so she thought until she was met with the uncanny feeling that Pinkie Pie was acting, well, a bit too equestrian.

Small oneshot based on the Official Equestria Girls blooper reel where it's implied the Pinkies from the two universes have traded places.

A RariPie story.

After the events of the Fall Formal, Rarity can't help but think about how things have changed.

Pinkie Pie is searching for something. She stops at Ponyville on a whim, or maybe that's the tingly feeling in her tail talking. She decides to meet some ponies. What better place to begin her quest than at Hayburger?

After a long day, Rarity returns home to the wonderful, loving surprise that is Pinkie Pie.
