When Leo, the city mouse, visits his friend Zoe in the countryside for the first time, he meets a huge and horrible monster. It's gigantic, has lots of horns and an enormous tail, and when it roars, the earth shakes. At least that's what Leo saw. Or did he? Zoe thinks his description sounds just like Bertha, the sweet-tempered cow in the field - back cover.

Penguin Pete befriends a mouse dwelling on a shipwreck, and finds that he has a lot to learn about life on board a ship.
