Trivia / My Little Pony: Friendship Is Magic S5 E21 "Hearthbreakers"

• Acting for Two:
  • Andrea Libman as Pinkie Pie and her mother, Cloudy Quartz Pie.
  • Ingrid Nilson voices all three Pie sisters: Maude, Limestone, and Marble Pie.
• Flip-Flop of God: Word of God stated Limestone Pie oldest of the Pie siblings, only for the writer to back down once called out for there being nothing in the episode making it explicit.
• The Other Darrin: In "The Cutie Mark Chronicles", Igneous was voiced by voice director Terry Klassen. Here, he's voiced by Peter New, the same VA as Big Macintosh.
• What Could Have Been: According to Jim Miller, the Big Macintosh/Marble Pie ship was thrown in for the other writers to expand upon. It was soon abandoned when they found the Big Macintosh/Sugar Belle pairing more feasible. Hasbro also got nervous about the possibility of Big Macintosh and Marble Pie being distant cousins.
