Ola was very fond of looking up at the sky. Every evening she and her cat Fluffy counted the stars. One day Ola decided to build her own rocket out of cardboard boxes. It was colourful and had big stars painted on the side. When everything was ready, Ola and Fluffy got in. Suddenly.... the rocket really lifted off! They flew higher and higher until they saw the blue Earth below them. They flew through the clouds until finally they landed softly on the grey ground of the moon. Ola put on a funny helmet and Fluffy got a tiny helmet. They got out of the rocket and, to their surprise, saw mysterious footprints leading behind a large silver stone. What's more, there was a soft blue light emanating from the stone. Ola looked at Fluffy and whispered: "Come on, let's see what's hidden there!" Slowly they moved behind the footsteps, getting closer and closer to the glowing stone.... And then suddenly they heard a soft sound, as if someone was calling them!
