Pinkie: "There can only be one Pinkie Pie in Equestria! And that Pinkie Pie is me!" Pinkamena: "Oh please! You're fighting me with cake! There's no way that you'll have a chance to destroy your past in the first place!!"
Oh yeah, love the dynamics. Still, the motion lines of Pinkamena's knife are following quite a strange path. She must have a veeery flexible (and extendable) neck to do such a move. Well, if anyone could do so, it would be her.
