Along with Maud, the entire Pie family was seen in the Season 5 episode "Hearthbreakers". In this episode, Pinkie has two more sisters -- Limestone Pie (oldest) and Marble Pie (youngest), the latter a lot like Fluttershy. Each Pie sister has a completely different personality. She has a main role in at least one episode of each season since Season 4, and has appeared in at least two episodes without Pinkie Pie, one of them being "Uncommon Bond", which focuses on Starlight Glimmer.
