In a quiet little town lived seven-year-old Tosia. She liked jumping in puddles and collecting colourful pebbles. One day, when the sun was shining very brightly, Tosia noticed that a shiny new cape had appeared in the garden behind the house. It was lovely and green like a frog! Tosia ran up to it and touched it with her finger. Suddenly she felt warmth in her hands, and her feet started... levitating just above the grass! "Oh my, am I really floating in the air?" - whispered Tosia in surprise. She saw her shadow on the ground doing funny pirouettes. At the same moment, a small, shy mouse looked out from behind a bush. It looked as if it too was looking for something. Tosia wanted to call out to the mouse, but suddenly she heard a strange whisper: "If you want to know the secret, follow the green hat...". Tosia glanced around, and the hat began to glide slowly into the garden. Would Tosia dare to follow him and discover where her superpower came from?
