Tosia really enjoyed playing in the garden behind the house. One sunny afternoon, as she was running on the grass, she suddenly noticed something strange under a bushy magnolia tree. Lying there was a colourful hat with yellow dots and a shiny blue ribbon. Tosia looked around - no one was in sight. - Where did the hat come from? - the girl wondered. She gently picked up her find and placed it on her head. Suddenly, she felt as if the wind had bewitched her hair, and the grass around her began to sing a quiet song. A tiny, smiling bunny appeared in front of her and bowed low. - Hello, Tosia! Are you ready for a magical adventure? - asked the bunny and winked his eyes. Tosia felt a thrill of excitement. Should she follow the bunny through the secret door that had suddenly sprung up in the hedge? Or was there something even more unusual hiding there?....
