The hamster in this book is not a happy chap. In fact, he’s very grumpy INDEED! But why? Perhaps it’s because his mummy is very cross. But why is she cross? Maybe it’s because her teacher was mean to her. But why was the teacher mean? Well her manager was always moaning so maybe that has something to do with it…

The story shows how bad moods and the grumps can spread from person to person – but how can you make this cycle of grouchiness stop? The little hamster doesn’t know the answer, but one day he meets a wise old pigeon who lets him in to a little secret. You don’t have to hold on to all the grumps! You can take that energy and turn it in to something good.

Can the hamster overcome his grumpiness and learn how to be happy?
