Notes:

Twilight derped big time in this episode. Sure by the end of it SPOILERS the real Pinkie remained and everything worked out, but the test was for the Pinkies to stare at a wall, and if distracted they get sent back? All she had to do was ask all of them "What element do you represent?" or "When is your birthday?" Simple questions would of made them find out who's the real Pinkie a lot easier. The test set out in this episode was to risky, if not unfair since you know.. Pinkie could of glanced to the side and WHOOP! Gone.
