The unthinkable has happened. A new Draconequus has emerged, apparently intent on plunging Equestria into chaos once more. To make matters worse, Pinkie Pie is nowhere to be found, forcing Twilight and the others to scramble to find a way to defeat this new threat without the Elements of Harmony.

Meanwhile...

After strange dreams, Pinkie Pie awakes and finds herself in the body of a Draconequus. Between strange new powers that she can't control, and, for some reason, an inability to communicate with other ponies, Pinkie finds herself alienated from her friends... but finds help from an unexpected source.
