Join the little mouse Armstrong on his hunt for the secret of the moon. Is the moon made of cheese or not?

The inquisitive little mouse Armstrong is fascinated by space, especially the moon. On a clear night, he observes it with his little telescope and is eager to learn more about it. The other mice claim it's made of cheese - but Armstrong doesn't believe it. How can he prove that the moon - like the earth - is made of rock? Finally, he sets about building a rocket in his attic to become the first mouse to fly to the moon. Will he make it? And what adventures await the brave little mouse?
