Will shorts be glazzed-out tomorrow? Are trumpet trainers just for bondos? What's whirrabubble next? Ask Posh Watson! Before he arrives, Crumble Lane School is so dull that the spiders on the ceilings yawn. The school uniform is grey, the classrooms cold and bare and the teachers as dull as dust. The only happy person there is Natalie, who spends all her time doing what she loves best, which is Maths. But then, enter Posh Watson, with his purple jacket, giant sunglasses, pink musical trainers, saying things like "abso-doodle-utely" and "hoo-doodle-ray". And, before you can say "fan-doodle-tastic", everyone is copying him - except Natalie, who thinks the whole school has gone mad.
