It was a lovely day in Ponyville. The sun was shining, the birds were singing and everyone was happy. Twilight Sparkle heard some news, it was bad news. Princess Celestia told her that her sister Nightmare Moon is going to attack Ponyville tonight!

They are off to visit Sweetie Belle, Applebloom and Scoodleloo at Applebloom’s farm to tell them the news that they received from Princess Celestia.

They teleport to the farm. Twilight Sparkle has a shocked look on her face as she approached Apple Jack’s little sister. She tells them what is going to happen tonight.

Later that day, Nightmare Moon reads a book about how to transform the ponies into evil ponies when the moon is blue and she will be able to control them. She turns Pinkie Pie into Pinkameaner,

Fluttershy into Flutterbat, AppleJack into Applebat, Rainbow Dash into Rainbow Death and, Rarity into Slender Rare.

Twilight Sparkle asks Celestia for help. Twilight Sparkle and Celestia use a vanquish spell on Nightmare Moon and banish  her to the moon. All her friends return to normal and everyone in Ponyville is happy.
