Little Strongheart is first seen assisting her herd in hijacking a train car containing Bloomberg and Spike. Rainbow Dash attempts to confront her as she runs on top of the train, but Little Strongheart manages to avoid with somersaults and weaves past her. Eventually, Rainbow Dash gets too caught up in the chase and crashes into a railroad post. Little Strongheart makes a brief cameo at the beginning of Pinkie Pride during the party Cheese Sandwich throws for the ponies and buffalo in Appleloosa.
