Marble Pie is a minor character in My Little Pony: Friendship is Magic. She is Pinkie Pie's younger sister and Igneous Rock and Cloudy Quartz' youngest daughter. Marble is also the sister-in-law of Cheese Sandwich and the aunt of 'Lil Cheese.
She first appears as a filly in a flashback in "The Cutie Mark Chronicles". She officially appeared as a fully grown mare in present day in the chapter book Pinkie Pie and the Rockin' Ponypalooza Party! and the season five episode "Hearthbreakers. "
Personality[]
Like Big Mac, Marble hardly ever talks, making various "Mm-hmms" and "Ummmm." She is also fairly shy like Fluttereshy. Instead, her sisters do the talking for her.
Despite her silence, Marble cares deeply for her sisters and can be forceful when the need calls for it. She glares at Limestone for failing to recognize Pinkie Pie in despair and convincing Limestone to call a work break to comfort Pinkie with a single look.
Trivia[]
To accommodate with Pinkie Pie, G.M. Berrow named Marble and Limestone so that they and Pinkie would have the initials "MLP."
