(Story idea suggested by JBlaster on FanFiction.net, think of it as a Rarity version of "Too Many Pinkie Pies". The exact timeline is vague but it takes place prior to any events in Season 9.)
Rarity finds herself facing a huge back order that pushes Carousel Boutique to the limits and drives her to madness. And the deadline is lurking just around the corner.
Deciding that she needs extra hooves to do the job, the fashionista settles on the idea to use the mirror pool and clone herself. But it isn't long before the clones take on a mind of their own and go crazy.
Luckily, Rainbow Dash is up to the task of rounding up the Rarity clones. But what she doesn't know is that these extra Rarities have their own plan in mind for the speedster, one that she will surely dread.
