One day a tiny insect, no bigger than a freckle, climbs into Miss Calypso's classroom. Nobody notices until... Polly scritches, Joshua scratches, and soon the whole classroom is scritching and scratching. An irresistibly catchy text and zany artwork - head lice have never been so much fun! 'It won't help you get rid of the little critters, but at least it will make you laugh as you scratch. A really jolly gift for all those children and parents (and grandparents) who get uptight about nits.' The Guardian
