Kiljusen Plättä

A mischievous pair of brothers, Mökö and Luru, return home for their Christmas break only to discover that their father has a surprise waiting—a newborn sibling they’ve never seen before. The baby, a tiny, bright‑eyed child who soon earns the nickname “Plättä,” instantly turns the household into a playground of clumsy curiosity and comic chaos.

From the first tentative peeks and whispered guesses about the infant’s abilities, the story follows the boys as they try to understand their new sister’s strange language of “plät, plät” and her uncanny knack for grabbing onto anything, especially Mökö’s hair. Their mother’s amused patience and the brothers’ relentless antics create a warm, lively portrait of family life in a small Finnish town, where every small discovery feels like a grand adventure.
