Mymlan, also known as Mymble, is a lively and somewhat vain character from the Moomin series. She is the older sister of Little My and appears as a spirited, independent figure with a strong personality. In different adaptations, she often serves as a comedic and slightly flirtatious presence, bringing energy and unpredictability to the story. Her role in the series is usually to contrast with the calmer characters, adding humor, charm, and a bit of mischief to the Moominvalley world.
