In the middle of a green forest, where the sun twinkles through the leaves, lived little hedgehog Julek. Julek loved adventures and ran every day with the squirrel Clare and the frog Frank. One morning, as they were walking together along the path towards the Forest Hill, they suddenly discovered something very strange. They saw large footprints on the soft earth that they had never seen before. Clare shook her tail and whispered: "Who could have been here? After all, these are not the footprints of any of our neighbours!" Franek blinked his big eyes and suggested: "Maybe it's the Treasure of the Forest Hill that's awake?" Yulek felt a thrill of excitement. They all set off together, quiet as mice, following the footsteps that led straight under the oldest tree in the forest. There, in the shade of the huge roots, something unusual awaited them. In the distance they heard a quiet rustling.... What could be hiding there? Should they look closer?
