Tosia enjoyed playing in her room very much. She had everything she loved there: soft cushions, crayons, and her beloved cat named Pixie. One rainy afternoon, her mother asked Tosia to clean up her toys. When the little girl pushed aside a large, old wardrobe, she discovered something strange - there was a flickering, colourful light on the back of it! - What's that? - whispered Tosia and called Pikus, who curiously came to smell the new place. Together they looked at the wardrobe and then.... the light started spinning faster until it formed a round, spinning hole, just like a rainbow portal. Tosia looked at Pikus and bravely grabbed him in her arms. - Why don't we see where this hole leads? - she asked, and her heart beat faster. She took a step forward and... Suddenly she felt a soft, colourful wind pull her in! The lights swirl around and the sound of children's laughter. When her head stops spinning, Tosia opens her eyes and sees a huge forest in front of her with trees growing out of books and flying teddy bears. Suddenly, from under one of the trees, she hears some mysterious whispering.... What or who is waiting there for Tosia and Pikus? Will they return home or will an amazing adventure await them?
