Many ponies, whether grown or foals, are sure to remember last year's Nightmare Night where Princess Luna came to Ponyville to celebrate the holiday with her subjects, and this year, it's no different.

Luna returns to Ponyville to celebrate Nightmare Night with her subjects again, but now, already knowing what this holiday is about, she decides to come to Ponyville in a costume.

Twilight and Luna are happy to see each other, especially at this year's Nightmare Night, and they decide to spend the holiday night together, just like last year's Nightmare Night.
