Now this was a delightful episode. "Too Many Pinkie Pies" was funny, well-paced, and quite sweet. Pinkie Pie is a ball of energy who loves having fun with her friends. When she has to choose between hanging out with Rainbow Dash and raising a barn with the Apple family, Pinkie remembers a legend about a mirror pond in the Everfree Forest that will allow you to duplicate yourself, and she takes advantage of it. However, the amount of Pinkie Pies quickly explodes out of control, and faced with a Pinkie plague, the town has to do something. Twilight discovers a spell to set things right, but first they need to determine which Pinkie Pie is the real Pinkie Pie - if they can.
This episode reminds me a lot of "Party of One." Pinkie can definitely be obnoxious, but she has good intentions and really cares about her friends. And Pinkie-centric episodes are nice when we get to see her as more than just a source of jokes. My heart went out to her when Pinkie started to see just how far in over her head she'd gotten and realized that she might get sent away from her friends as a consequence of her actions. The other ponies all got some screen time, and I liked the callback joke with the orange frog. The throwaway reference to the older MLP series was a nice touch too. I don't have much to say about the specifics; if I were to pick out the good moments I would have to talk about most of the episode. Overall this is a very solid episode and promises good things for season three.
