Meet Dirty Bertie - a boy with nose-pickingly disgusting habits! He's full to bursting with madcap plans and crazy ideas, and if it's trouble you're after, look no further - Bertie's sure to be up to his neck in it. Bertie devises a new scheme for making filthy lucre, has a sickly time at the fairground and manages to teach a toddler her first word: Bum!
