She was in the audience with the marching band in "Got Stank?" when she scolded Bucky for doing his "solo". When Bucky was stanked by the Sorcerer the ninja came to the band's rescue and also saved her flute which she named Princess Tootie. She appeared judging Randy's tryouts for the band along with the Band Leader. She watched the ninja destank Bucky and laughed at him for being "naked". However, she was shown comforting him after Randy tricked him into going up the volcano in "Monster Dump". She was also seen briefly in Monster Drill where she was chosen to pretend to be a monster for the school's annual drill. She was paired with Howard in the episode Monster Dump since she was considered a good student by Mrs. Driscoll. She ended up going with him to the volcano because of the "five-foot rule". Flute Girl, Howard and Bucky were captured by Viceroy's amoeba monster in the volcano but the ninja saved them, causing Flute Girl to thank him for saving their lives. In "McFists of Fury", she got angry at Randy and Howard for not knowing who Brawn Brickwall was at the McFistory History Pavilion. She also might have a crush on the ninja, because she is seen being all mesmerized by the ninja and such whenever her saves her from monsters, although she is not aware of the fact that Randy is the Ninja and she thinks he is an idiot.
