The Pinkie Pie clones are gone. They have all been zapped back to the Mirror Pond. All, except one.

This particular clone knew that if she stayed around Ponyville, she would be spotted, and end up just like all the other clones. And she didn't want that. So what else is there to do? Escape Ponyville, and to where? Manehatten. Meanwhile, a certain blue unicorn mare is busy trying to make herself look better while ultimately failing. Surprises will await them both.
