Pinkie is throwing yet another party, and this time, she's pulled out all the stops. The cupcakes, the treats, the party games and the guests, even a big musical number; everything is of the best Ponyville has to offer. However, one pony in particular isn't happy about the party. Not one bit...

Will Pinkie Pie be able to reconcile with Fluttershy? If so, how will their relationship blossom?
Hilarity, d'aww, trademark Pinkie Pie randomosity, and tasteful breakage of the fourth wall...
