Pink stinks? Not at all! Rosa is cheerful, cheeky, and brave, often seen in overalls and loves to climb the tallest trees. But more than wearing her three brothers' pants, she wishes for a pink ruffled dress and a crown - just like a princess! However, her parents' little farm in Grillenwinkel is not a castle, and the only pink there are the piglets in the barn. Luckily, Rosa has her donkey! He is actually a unicorn, can talk, and has many great ideas. Sometimes even too great... Will the two of them manage to make Rosa a real princess after all?.
