Lena and her little brother Robuś loved looking at the stars very much. One evening, when it got quiet in their room, Lena whispered: "What if we flew into space?" Then, completely unexpectedly, a colourful rocket appeared in front of them! Lena helped Robusi put on his astronaut helmet, and then together they jumped inside the vehicle. The rocket was as soft as a pillow and smelled of fresh cookies. "Prepare for launch!" - called out the on-board computer. Suddenly they felt a slight tickle underfoot. "Countdown! 3... 2... 1... start!" - they heard. The rocket shot upwards, all the way past the clouds. After a moment, Lena saw through the window a huge, shiny planet with purple trees and glowing pebbles. When they landed, the rocket doors slowly opened. Behind them waited a mysterious path leading deep into a forest of star trees. Lena heard quiet laughter and Robuś noticed something moving among the leaves. Was it a space creature? Or did someone want to invite them to their game? Lena and Robuś looked at each other with wide eyes and took their first step onto an unknown planet, not knowing what awaited them next....
