Twilight thought the Breezies were just a myth. But when Spike begs her to turn him into a pony, a spell she uses turns him into one of the mythical fairy ponies.
NOTE: This is kind of one-shot, if that's the word, because I'm just going to post it and not edit it much. It's just for cute fun. I was watching a video of G3 ponies and there were these tiny fairy ponies called Breezies and I thought they were cute so I wrote this.
*THIS IS NOT A SHIPPING STORY. I do not like the Spike/Rarity ship as he is a little boy and she's a grown woman. Please do not try to claim it is.
