Last one for today on facts is Marble Pie, who, like Limestone Pie, was first seen as a filly in Pinkie Pie's flashback in The Cutie Mark Chronicles before making her debut as a grown mare in Hearthbreakers:
* She is the second mare in the show's history who has been involved a romance with Big Mac, following Cheerilee
* She is the second sister of the Pie Family to have been involved in a romance with a stallion, following Pinkie Pie, who is involved in a romance with Cheese Sandwich.
* She is the third pony, and the only female to date, who has "Marble" somewhere in her name, following Black Marble (Season 1) and White Marble (Season 5).
