Pinkie Pie lived with her parents and her two older sisters (Maud and Marble), but was kicked out of the house as a child by her own parents.
She spent time wandering through the woods until she found the Apple farm. So she moved in with them, she considers the Apples as her real family.Today, she lives with Applejack in a cabin in the woods near the village. Together they adopted Scootaloo.
She is a very lovable and gentle pony. She is always willing to help creatures, be they ponies, griffins or dragons. Pinkie is also someone very detail-oriented and idealistic.
She is also good friends with Gilda, Gabby, Derpy, Moondancer and Rainbow Dash.
