Maks and Lena were siblings who liked to spend afternoons in the woods behind their house. They always walked together, with their kitten named Fluffy slowly trotting behind them. One day, Max noticed that the old oak tree looked different than usual. Something had grown under it that resembled a large, shiny frame. Lena walked closer and touched the frame with her finger. Suddenly she felt as if her finger had gone through water! Fluffy jumped boldly into the frame and.... disappeared with a quiet "meow!". Maks looked at Lena: "We have to go after him! Fluffy might need us!" Although Lena felt a slight tickle in her stomach, she grabbed her brother's hand firmly and together they walked step by step through the shiny gate. On the other side, they suddenly found themselves in a place that looked very different from their forest. The trees had blue leaves and the sky shimmered with all the colours of the rainbow. Fluffy was sitting on the strange, downy grass and looking at a large golden clock hanging from the branch of a nearby tree. Suddenly, a quiet rustling sound came from the bushes and something bright shimmered between the branches. The children looked at each other with wide-open eyes. What could it be?
