These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: My Little Pony Friendship Is Magic S 1 E 20 Green Isnt Your Color
The Scrappy: Pinkie Pie is this for the episode, due to her constant popping up to keep Twilight from confessing on what Fluttershy and Rarity think about each other, which would have solved the episode's problems. And even at the very end, after Rarity and Fluttershy tell the truth to each other, she's off the hook on their secrets, but blurts out the "Spike loves Rarity" secret...despite the fact that everypony knows about it, and Pinkie's disappointed at that.
Squick: Fluttershy's magically forced nose-picking scene in the second fashion show. The ponies (even Derpy) in the audiences were really displeased.
