NEWS: Fluttershy's apology for the "Pony Life" trailer mishap · 10:41pm Dec 30th, 2019
So today I learned that the Pony Life trailer was suddenly pulled by Hasbro, likely because it featured ponies lip-syncing to the song "Good as Hell" by Lizzo. Ponies saying the word "hell" did not settle well with fans, and the video was subsequently pulled.
Fluttershy would to apologize on behalf of all the Mane 6 for the error:
Fluttershy: "I have only one thing left to say."
