Tosia lived in a small house on the edge of town. She loved to explore different nooks and crannies, and her best friend was her dog Pod. One day, when her mum asked her to tidy up the attic, Tosia found an old wooden cuckoo clock in the corner. It was very ornate and there were strange stamps on the dial. Donut started wagging his tail and barking around the clock. Tosia decided to wind it up. As she turned the key, the clock started ticking louder and louder and the cuckoo jumped out... only it didn't stop in its place! Instead, it spread its tiny wings and flew around Tosia. The room swirled, and Tosia felt the world slipping out from under her feet. She closed her eyes - and felt the grass under her feet, and the warm breeze blowing down her cheeks. Pod was standing right next to her and looked very puzzled. Looking around, Tosia noticed that they were no longer in the attic. They found themselves in a strange forest, where the trees had colourful leaves and birds sat on the branches singing completely unfamiliar melodies. Pod sniffed the air - it smelled of honey and something else that Tosia couldn't describe. Far away, between the trees, something silver flashed, and the cuckoo that had brought them here unexpectedly disappeared into the thicket. - We have to find it! - whispered Tosia to Pod, feeling a touch of excitement and anxiety at the same time, because when she looked ahead, she saw that there was something standing among the colourful trees that she had never seen before.... Should they go up there?
