One rainy afternoon Ola was sitting on the carpet in her room and stacking blocks. Suddenly she noticed something strange in the wall - a small, colourful door that had never been there before! Ola walked closer. The door was red with yellow dots and there was a tiny bell hanging on the handle. When Ola touched the handle, the bell chimed softly. A soft laugh came from behind the door, as if someone was playing there. Ola glanced around - her stuffed rabbit sat right next to her, as if it wanted to enter together with Ola. Ola took a deep breath and opened the door. Behind them she saw a fabulously colourful world: flying fish, trees made of candy canes and a big blue puddle that suddenly... moved! Ola took a step forward and then she heard a quiet whisper: "Who is here?" What did Ola see there? Would she dare to go further through the magic door?
