Trivia / My Little Pony: Friendship Is Magic S2 E13 "Hearth's Warming Eve"

• Blooper: During "The Heart Carol" at the end, the ponies in the audience are shown singing with the Mane Six, but after the shot of the CMC, the audience ponies have their mouths closed.
• Missing Episode: The Hub seems to treat this episode as a holiday special, meaning it will only air once each December. The series will rerun from front to back many times over the course of a year before this episode makes another appearance.
