Pinkie Pie has four cousins she used to spend a lot of time with when she was younger. Pinkie decides to have a reunion with her three favorite cousins. So what happens when number four isn't invited?
Will Ponyville survive the invasion from Tumblerville?
Will Pinkie Pie be able to keep her cousins from fighting?
Will my mind be able to handle this level of pony?
Heck if I know.

Archivist Note: I blame tumbler.
Will add character tags and etc as needed, because I have no idea where I'm going with this.
