Once upon a time, there was a smooth, round planet. On this planet, there were two friends - a cat and a dog. They liked to play and have fun together.
One day, the cat said, "I want to escape and see other planets!" The dog agreed, "Yes, let's go!" So, they built a big, red rocket ship to fly away.
They went up, up, up into the sky. They saw many new planets. Some were big and some were small. The cat and the dog were happy to explore them all. In the end, they went back to their smooth, round planet, where they played and had fun together.
