When Lisa goes to school, she encounters dwarfs in the form of fence posts on her way in winter, helps the chestnuts crying for help out of their prickly prisons in autumn, and flutes with the blackbirds in chorus in spring. Her mom says Lisa just has too much imagination. She should focus more on ballet, horseback riding, swimming lessons, piano class, and math tutoring. Just like her brother Jonas, who manages to do all of that effortlessly. But when Lisa hears about her mother's plans, she feels dizzy. When will there be time to catch her breath? Luckily, one day Lisa accidentally ends up in a small craft shop and meets the owner, Mia. Together with her, Lisa felts a round, blue fluff. Mia helps her attach the fluffy thing to her school backpack so she can always have it with her.
