Party with Pinkie [SFM]

Here it is, all nice and done! Pinkie Pie is my favorite pony.
Crapsack, uh, I'll let you guys know that there is one huge mistake in this video. And if you can point it out without starting a war, you get a cookie.
After making this, I actually wish I didn't have to spend so much time into it, and probably for some amount of time, will be making small shorts to kind of up my efficiency at animation.

I may be preoccupied with other projects for a while, but I'll still work on other videos.
