As the chaos surrounding the mirror pool died down, and the original Pinkie Pie was reunited with her friends, the Mane Six had assumed that all was well and good, and they'd gathered up all of the extra Pinkies.
Never make assumptions.
In a valiant effort to escape the fate of being cast back into the mirror pool, the remaining clones gathered their own identities and fled to the best hiding ground for multiple copies of the same pony they could think of: Manehattan. On the first train out of dodge, they set about the city and scattered to the wind.
Though not without promising to meet every week and exchange notes. Welcome to Pinkie Anonymous.
