The plot of this small hardback is simple – a boy and his mum catch a bus, go shopping and visit the park.

On the way the boy makes friends with all sorts of creatures, from an ant to a butterfly to a kitten, until finally he meets a human friend.

The black-and-white line drawings, enhanced by splashes of yellow to pick out the mum, the boy and the creatures, perfectly capture the boundless curiosity of a young child, giving the book a timeless appeal.
