Behind Zosia's house there was a big, green forest. The girl loved to go there together with her cat Fikus. One morning, when the sun was shining particularly strongly, Zosia found a sparkling silver feather under an old oak tree. "Ficus, look! Isn't that a fairy feather?" - she whispered in surprise. Ficus meowed and moved his whiskers. They both set off on a trail of feathers that led deeper and deeper into the enchanted forest. There were strange sounds all around them: quiet whispers, laughter and gentle humming. The trees grew denser and denser and the sun's rays danced on the mosses like sparks. Suddenly, Zosia heard a shadowy voice: "Help!" The girl looked around, but saw no one, only small silver wings sticking out from under a huge, aged leaf. Zosia and Ficus leaned closer and then.... the leaf started to move!
