>>29281215>Not Enough Pinkie PiesDue to some unexplained magical plot device, Pinkie Pie is the only one of the Mane Six available to face a menace that's threatening to destroy Ponyville and eventually all of Equestria. Out of desperation, she visits the Mirror Pool again and summons the Pinkie clone army. Together, the Pinkies manage to save the day.
Then comes the hard part: Pinkie has to convince a paranoid Twilight Sparkle that (1) she knows that she is, in fact, the real Pinkie Pie, and (2) she has managed to teach the Pinkie clones that they are, in fact, magical constructs and (3) the clones are willing to go back to the Mirror pool on their own.
