Are you ready for the biggest story? Errol's mum is too busy to tell him a story because she has to do grown-up things, but he's really, really bored. "Why don't YOU think of a story?... his mum suggests.

But Errol thinks this is a silly idea. He doesn't know how to tell a story ... So he goes out to the garden to think.

Just as he's starting to give up, he's joined by a surprising host of different animals who inspire him to tell his story. They gather round to listen and a story begins to grow and grow and grow ... until it's the BIGGEST story ever!
