Now draw a companion piece with Rarity's "I Want To Be Alone" cloak from Green Isn't Your Color, Rainbow's ninja outfit from the Daring Do episode, and Applejack wearing the Mysterious Mare-Do-Well outfit.
Good question. I totally forgot about that episode too. Although looking at it, the costume was rather meh designed. If they gone for some specific look (ninja would look good), I bet it would be remembered better.
