- Jossed: A common theme among fanfic writers is that Fluttershy is secretly a Nightmare Fetishist. Turns out that while she has a talent for scaring her friends, she really doesn't like it. Though she is apparently a fan of the Ponyverse equivalent of Neon Genesis Evangelion, for what that's worth.
- Short Run in Peru: This episode aired a week early on Canada's Treehouse TV.
- Schedule Slip: Was meant to be aired in between "Canterlot Boutique" and "Rarity Investigates". But Hasbro and Discovery Family held off on it since it was nearing the Halloween holiday at the time and Halloween falling on a Saturday of that year (2015). However, the episode was leaked early to iTunes and wound up online before then.
