FATHER CHRISTMAS NEEDS A WEE (PB)

At each different house that he visits Father Christmas drinks and eats all the goodies left out for him. Before long he really, really, really needs a wee. So much so that he even forgets to leave the presents behind. But he dashes back, delivers all the pressies and flies home at high speed to avoid an embarassing accident. There's just one tiny problem- he's lost his house key!
