Each pony in the Mane 6 wakes... to find that they are one of their best friends, although keeping their personalities and colours in their new shape. The six mares must adapt to this new life, but it won't be easy. What will happen if somepony finds the key to Pinkie's dark secret, or Rainbow's stash of Playpony magazines?

Hilarity will ensue, that's what.
