Scootaloo is one of the Cutie Mark Crusaders. She's a pegasus but she cannot yet fly. Says "bawk!" like a chicken sometimes, which she is constantly called by Apple Bloom. Thanks to a quote by my brother, when trying to explain to my mom who the Cutie Mark Crusaders were to the other ponies, "Sweetie Belle is Rarity's sister, Apple Bloom is Applejack's sister, and Scootaloo is.. Rainbow Dash's.... son," Scootaloo is now Rainbow Dash's son but a girl. Whatever the girl version of son is.
