Someone's Perfect Poo - Felicity Cannell - Bog

Welcome to the world of the Poobugs!
The Poobugs live deep down in the Tunnel of Been, in Someone's tummy, and work hard to make perfect poo. They can, however, only work with what comes down the tunnel, so the story is told through four hilarious stages with various outcomes depending on what Someone is eating. Someone can be naughty and troublesome and that causes the Poobugs all sorts of problems, and things get very messy! Until, with the right ingredients, they succeed in making a perfect poo.
