Pannet is a young rabbit girl who lives in the same town as Karl and is described as his closest friend. She works as an apprentice bread maker and is still very much in the middle of her training, so she has not yet mastered the craft she has chosen to pursue. In her town, residents devote themselves to the one occupation they love most, and for Pannet that occupation is baking, which makes her apprenticeship a meaningful part of her identity. Her personality is calm and easygoing, but around Karl and their friend Rolo she tends to take on a slightly older-sister manner, and she also has a quietly strong-willed side beneath her gentle demeanor.

In the story she is a supporting character who belongs to the central group of three children. While Karl is the curious and adventurous one who dreams of the wider world, Pannet acts as a steadier and more grounded presence, offering warmth and a sense of responsibility to the group. Her bond with Karl is the strongest, since he is her best friend, and she treats the timid Rolo almost like a younger brother, naturally slipping into the role of looking after him. Her motivations are tied to her dedication to her bread-making apprenticeship and to being there for the people she cares about.

Pannet does not possess flashy or unusual abilities. Her most notable strengths are her patient temperament, her dependable nature, and her caring instinct toward others, along with the modest but genuine commitment she brings to her baking. Because she is still learning her trade, her skills as a baker remain in progress, and she is defined more by her supportive role within the group than by any single standout talent. She is essentially a loyal friend whose quiet maturity helps hold the trio together through the events of the series.
