Based on Cupcakes. When something happens that no one can foresee the mane cast will learn just how far fear can affect their group.

Now a rainbow's tale isn't quite as nice as the story we knew of sugar and spice.
But a rainbow's easy once you get to know it with the help of the magic of a pegasus device.

We all know the story of the Rainbow Factory, of how Rainbow Dash had gone mad and done unspeakable horrors. But how did it all come to that? How was it that Rainbow Dash, known for her loyalty, descended into such madness? This is Rainbow Dash's story of losing herself to that dreaded factory, for as we all know, in the rainbow factory not a single soul gets through.
