Sly Cooper. Greatest thief in the world. None can match him for his speed, clever mind, and wit. However when a job goes wrong he finds himself in a world completely different to his own. However he didn't come over alone.

This is a crossover with Sly Cooper and this takes place after the third game. I haven't played the fourth game yet so this is technically out of canon for both worlds. You will not have needed to play the games to understand what's happening with the characters of Sly Cooper in their world or in Equestria. I will explain things as the story progresses.

Pinkamena "Pinkie" Diane Pie is Us. In crazy brilliance, We made Pinkie so strange that We would never be suspected, and it worked until the very end. An end that came about, not because We failed, but because of inescapable circumstance.

Now, We must run.

We do not want to think about what they will do to Us if they catch Us.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

"YOU ARE NOT THE REAL PINKIE PIE!"
"You probably shouldn't even exist."
"You're only a clone, you don't HAVE any feelings!"

Who was she to believe? She was barely a day old, and already she'd seen the disappearance of her mirror images, all but her. Was she just a clone? A disposable unfeeling analog?
What would happen if she became her own pony? If she became real?

Is it possible for one of the Pinkie's, the only copy left behind, to develop? To become an entirely different pony to the one that she was modelled after?

Oh, and before I forget, thanks to the amazing WerewolfNobody for the (At one point) cover art!

When Fluttershy received her certification as a fog specialist, she only wanted a plausible excuse to write off the expenses associated with her ground-based house on her taxes. However, when an accident in Cloudsdale sends a blanket of industrial-grade clouds rolling towards Ponyville, Fluttershy suddenly finds herself in charge of coordinating the response, mostly because she's the only fog specialist in the area. Can our heroine step up to the challenge at hoof, or will she risk facing the wrath of the Equestrian Revenue Service?

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

When Pinkie Pie ignores Zecora's warnings about the proper preparation of chuckleberries, she ends up locked in a battle with Sugarcube Corner's kitchen. Not just IN the kitchen. WITH the kitchen. Only Pinkie could be in a situation this ridiculous.

Applejack had long since taken the Hearth’s Warming Eve story for fact. When she and Fluttershy find themselves in an untamed wilderness, they’ll learn that not all history is preserved. In their struggle to find their way home, the two will unearth secrets unknown to any living being, pony or otherwise.

Half a world away, the others have problems of their own. As Rainbow Dash struggles to discover exactly what she is to her oldest friend, Twilight must face the stunning truth about her long-time mentor.

In the end, what is lost, and what is found?

In the far north, where changelings live, change begins -- a single changeling breaks out of the collective mind, becoming an individual. The story follows the life and adventures of Chip -- a changeling that will bring upon a new era in the Hive.
