There are many stories to be told in the wide world of Equestria, but only several are pure chaos. Pinkie Pie finally perfects her fourth wall breaking antics and breaks into Studio B to commence her own story writing. Unfortunately, she's backed up by the tens of thousands of fan mail letters sent in! The Mane Six's lives are turned upside down and inside out by the crazy imaginings of fans and the increasingly insane Pie.

After a wild night of partying, the Mane Six, along with the Princesses and the CMC, wake up to find their lives have been twisted. Some have achieved their wildest dreams, while others are living in a distorted version of their normal lives, all trying to solve what happened last night and get everything back to relative normalcy. With Pinkie Pie at the handle, and the wishes of thousands of fans at her back, one thing is clear: Equestria will never be the same again!
