Family and Cutie MarkEdit
Pinkie Pie tells the Cutie Mark Crusaders in The Cutie Mark Crusaders that she was raised on a rock farm with her two sisters and her parents. Her father wears a pilgrim's hat, her family's coats and manes are Earth-colored, muted browns and grays, and they all wear somber expressions until Pinkie Pie discovers her special talent.
When Rainbow Dash's sonic rainboom clears the clouds and paints a rainbow across the sky, the shock wave frizzles Pinkie Pie's hair giving it its distinctive curl, a visual gag that was concieved by Jim Miller. The sonic rainboom that she witnesses makes her smile, and she then decides to dedicate her life to making people happy and throwing parties. When she invites her family to their first party ever, her mother calls her Pinkamena Diane Pie. The family joins Pinkie, and they all shakily start to develop smiles, and eventually merrily participate in Pinkie's party.
Role in the SeriesEdit
Pinkie Pie is an ally to the Shell Lodge Squad just like the rest of her friends. She is the most favorite of the Lodge for her very funny antics. She is also hinted to make the entire Shell Lodge laugh by just saying "Doi!". She's capable of making anyone smile, or even laugh...almost (A Friend In Deed). She was even capable of getting the depression-feeding spirit Anima out of it's host by being funny.
