- Actor Allusion: Shining Armor's name is Francis Sparkle, according to Twilight. He is voiced in the actual show by Andrew Francis.
- Cross-Dressing Voices: Anypony voiced by Griffin Lewis. Silver Spoon in particular sounds a lot like Lumpy Space Princess. And Celestia sounds more like a queen than a princess.
- There's a group that wants to create a real life version of Sweetie Bot.
- For a time, BBBFF had a website, based on NSYNC's website from the 90s, before it was eventually taken offline.
- Fan Nickname: Sweetie Belle gets called Sweetie Bot. No points for guessing why.
- I Knew It!: Sherclop Pones somehow successfully predicted that Twilight has a brother (Shining Armor, introduced in "A Canterlot Wedding"), that Pinkie Pie is a gypsy (as of "It's About Time"), that robots exist in some capacity (a nerd pony has a robot-based Cutie Mark in Putting Your Hoof Down), that Twilight will become a princess ("Magical Mystery Cure"), that the Humane 6 would start a rock band, and that Smooze would be returning (and has since done so in "Make New Friends but Keep Discord"). They also kind of hinted at the tensions between Big Mac and Applejack over their relationship with Applebloom. In Friendship Is Witchcraft episode 7 when Applebloom says "Bring back my favorite sibling" as it pans over Big Mac.
- Meme Acknowledgement: In "Swarm of the Century", Twilight suggests building a giant book fort and living in there. "It'll all be secret but fun."
- Name's the Same: Princess Molestia (aka Luna) is not to be confused with Princess Molestia (a Memetic Molester version of Celestia) or Ask Princess Molestia (an Ask a Pony blog based on the same concept).
- The Other Darrin:
- Rainbow Dash is voiced by Keesha Bush-Trenerry in "The Perfect Swarm" and Jenny Nicholson in all subsequent episodes except for a brief gag in "Cherry Bomb".
- Kyle Travers voices Mayor Mare in "Lunar Slandar" but in "Cherry Bomb" is replaced by Bronymike.
- Quote Source: Lyrical Dissonance.
- What Could Have Been:
- Planned a collab with My Little Pony: The Mentally Advanced Series and they were thinking of making an extended version of Princess of the Night. Both of these plans, sadly, fell through.
- Jenny occasionally posts outtakes on her tumblr. Behold:
- Sweetie Bot appeared as a 8-bit video game character in two Hot Diggedy Demon episodes that were shown in a bronycon convention. Here.
- The intro in the 6th episode (There is no Bro in Dole!) is based on the reaction former MLP:FiM download site, Ponyarchive, had when they were given a cease and desist letter from Hasbro.
