Behind the town was a large park. Old oak trees grew there and starlings sang on their branches. In this park Lena played every day together with her dog Fafik. Lena was curious and liked adventures, and Fafik always ran happily around her, wagging his tail. One sunny afternoon, Lena noticed something shiny lying under one of the benches. She carefully picked up the material, which turned out to be a soft, colourful cloak. Lena threw it over her shoulders and suddenly she became.... invisible! - Fafik, look! - she called out, but Fafik looked around puzzled, searching for his mistress. It was only when Lena took off her cape that the dog happily sniffed her and licked her hand. Lena realised that the cloak gave her the superpower of invisibility. That day, Lena and Fafik played hide and seek like never before. Lena would sneak invisibly up to the birds and watch them closely, while Fafik would run and look for her tracks in the grass. But then, by the thick bushes, Lena heard a quiet rustling. From behind the green leaves, something moved. Fafik set his ears and gave a quiet murmur. Lena, wearing her cloak, took a step closer. What was hiding in the bushes? Would they dare to check it out together?
