Thirty Moons
The Equestria and Canterlot High versions of the Mane Six trade places.
Several weeks after recovering her crown from Sunset Shimmer, Twilight Sparkle discovers she can communicate with her counterpart from the other world, who has finally arrived at Canterlot High. When Celestia theorizes that the portal can be re-opened, Twilight and her friends--as well as the OTHER Twilight and HER friends--decide to trade places, so they can learn more about each others' worlds. The only catch: neither party can return to their own world for a full thirty moons...
