Summer Sun Celebration is coming, and it is up to Princess Celestia's favorite student, an Earth Pony named Pinkie Pie, to supervise the preparations. Oh yes, there's also an ongoing rumor about Nightmare Moon's return, but who would worry about that you silly filly!
Princess Celestia sends her pupil (along her dragon sidekick Spike) to Ponyville where the Party Pony Extraordinaire will meet with five other ponies. Let's hope that nothing will interrupt the party, like a lunar ancient evil party crasher. Nah, everything will be just fine.
Alternate version of "Friendship is Magic" with the Mane 6 playing different parts. Contains lots of silly references!
