Appearances in Christmas specials[]
Igneous Rock Pie and Cloudy Quartz have major roles in "Hearthbreakers" when the Apple family and Pie family spend Hearth's Warming Eve together. In this episode, they are depicted as stereotypically Amish, speaking in old English and acting very traditional. Initially unreceptive to the Apples' traditions, Igneous Rock and Cloudy Quartz eventually come to accept them, with Igneous even trying to adopt some of Granny Smith's country mannerisms.
In the holiday special My Little Pony: Best Gift Ever, Igneous and Cloudy appear celebrating Hearth's Warming Eve with their and Applejack's families.
