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. Join Bertie as he tries to get out of a pink party, fails to be polite for a whole day and a makes really rubbish entry into the summer fair's flower arranging competition...
