On the way to explore the world, a little kiwi, 'Kiwiwi', meets a mouse.
The little mouse explains about the many animals they may encounter and in the process they become friends.

A glossary is attached for readers and self-readers which describes the different animals in more details. Attention is also drawn to the dangers the native animals can be threatened by. Especially by those animals that were introduced into their habitat by people.

Nevertheless, the book is unreservedly recommended for children because it does not directly address this current situation. It just depicts the animals and goes into the developing friendship of the two quite different main characters.
