MMC: Mare in the Moon

Twilight Sparkle goes to Ponyville to prepare for the Summer Sun Celebration. There, she meets a wide variety of ponies: A hyperactive mare who picks apples, a pompous unicorn who focuses more on controlling the weather, a southern belle seamstress, a loud and brass veterinarian, and a strange but surprisingly social pegasus party pony. But will a certain dark mare ruin all that?
