Behind the big green hill was a forest that was said to be enchanted. This is where Zosia, a girl with a storm of red hair and a great curiosity about the world, lived. One sunny morning, when the birds were singing their merry songs, Zosia decided to go for a walk in the forest. As soon as she stepped under the tall, old trees, she felt something unusual in the air. The sun was coming through the branches, painting golden flecks on the ground. Zosia crouched down to watch the colourful insects and collected leaves in strange shapes for her treasure box. Suddenly, she heard a soft sound, as if someone was calling her by name. She looked around carefully, but saw no one. So she walked on, looking behind bushes and under stones. That's when she noticed tiny paw prints on the soft moss that glowed blue! They were completely different from the footprints she knew. Zosia followed them, placing her feet very carefully. Suddenly, a rabbit in a blue waistcoat jumped out from behind a large fern.

Perhaps you can help me? Zosia was so surprised that she couldn't say anything for a moment. But then she smiled broadly and nodded.
