Antek, Lena and Philip loved spending their holidays in their grandmother's village. Almost every day they went on expeditions in the surrounding forest, discovering more and more new places. One morning, when the mist was still lazily drifting between the trees, Antek spotted something unusual - a thin, shiny bridge stretched over a stream. It was no ordinary bridge made of planks or stones, but woven from a web that shimmered with all the colours of the rainbow. - Hey, look! - whispered Antek, pointing with his finger. - Is this... a bridge? - It's never been here - muttered Lena, moving her hand over the braided threads. - It's like a fairy tale. Philip, always curious, dared to be the first. He carefully put his foot on the spider bridge and lifted it slightly, as if to help get to the other side. The children looked at each other and set off together. After a few steps, they felt the world around them change - the trees grew taller and the leaves shone with a soft blue light. There was a smell of vanilla and cinnamon in the air. As they crossed the bridge, they heard quiet laughter and whispering. In front of them, among the huge ferns, a figure appeared - a translucent girl with silver hair and eyes like a puddle after a summer rain. - Who are you? - She asked. - Since you have come here, you must solve a magical riddle. But be careful... if you don't answer it, you might stay in this forest forever! Antek felt his heart beating faster. Lena and Filip clasped hands. More strange shadows appeared among the rustling ferns, and time seemed to pass more and more slowly. The girl raised her hand, and mysterious luminous letters began to dance in the air. What would happen if they didn't guess? Is the girl really friendly? The friends looked into each other's eyes, gathering the courage to answer the first riddle....
