Moxie is not really a bad girl, but is secretly a straight-A student. She makes one appearance in "Girls Behaving Oddly". In the episode, Kuzco appears to like her more than he does Malina. After Mr. Purutu reveals that Moxie's a straight-A student just like Malina is, and Moxie adds that she doesn't like being "hassled," so she prefers keeping her grades and schoolwork a secret.
Moxie was often seen accompanied by two other girls. These two girls make a non-speaking cameo in another episode, but Moxie herself has not appeared again since "Girls Behaving Oddly".
