Percy, the park keeper is having a sleepless night. A storm is raging outside his hut; there is thunder and lightning and pouring rain, but worst of all, there is the wind! When Percy gets up following morning he expects to have a lot of clearing up to do in the park -- but it is even worse than he imagined. The old oak tree which was home to many of his animal friends had been blown down. Where will Percy's friends live now? Percy sets off and very soon has devised a plan, the results of which produce a very big surprise indeed! 'One Snowy Night,' Nick Butterworth's first picture story book about Percy and his friends was an instant success and has already sold almost a quarter of million copies. Now Percy the gentle park keeper and his friends appear in a brand new story.
