'Every morning on our walk we see an amazing zoo, full of astonishing animals. Come and see them too!'

A sister, brother and grandpa walk through town on their way to school, passing lots of construction sites as they go, seeing all the busy machines. They imagine that each one is an animal - the concrete mixer's big round belly is like a hippo's, the digger stretches its long neck like a giraffe, and the jackhammer hops up and down like a kangaroo.

Vibrant and engaging whimsical fun for machine-mad kids.
