;D

I like how this story is starting out. I also like how she didn't even remember her actions or writing in her diary like that.

I wonder what will happen next. Will this start happening more and more? And is this just another side of Pinkie Pie, or is it a whole nother entity entirely? Or does Pinkie Pie just have that disorder that polar bears get?

Also, a similar story to this could be made about Fluttershy, since she does have a hidden mean streak of her own. And also Twilight Sparkle and Rarity as well. I guess you could find something in each of them that you could make a similar story with.

It's really good :)
