Luna was having more fun than she expected at the Nightmare Night festival. She bobbed for apples, threw spiders and made some wicked new friends! However, when Luna decided to lend somepony a hoof while putting away a pumpkin catapult, something hoes horribly awry.
Now Luna is stuck with a broken jaw, and Celestia decides to take it into her own hooves to humiliate Luna as much as possible.
Why?
It took Celestia four weeks to grow all that fur back.
FOUR. WEEKS.
--Based on an idea I just couldn't get out of my skull.--
