Background Pony #1C69

Applejack, Rarity, and especially Pinkie Pie have made use of prehensile tails before. (Applejack instance being holding a rope with her tail rather than the below-mentioned instance of brushing Rainbow Dash's face. This was in the sixth episode of the series too)



It's a bigger deal for Fluttershy because it debunks the rumor of her using tail extensions. (before this episode she didn't often make use of her tail unless she was Discorded or Flutterbat, but she DID pick up the Breezies with her tail if I remember correctly)



Of course any uses she has for her tail as her true self qualify as cute, because Fluttershy. :)
