Being a baby, Flurry Heart is innocent, naive, and hyperactive, demonstrated throughout her debut in The Crystalling - Part 1 and The Crystalling - Part 2. In A Flurry of Emotions, she displays a more emotional side, frantically searching for her toy Whammy, and crying and avoiding her aunt Twilight when she gets frustrated with her. In the same episode, she is shown to be friendly and kind, trying to help Pound Cake and Pumpkin Cake but accidentally provoking them instead.
