Something is AFOOT! Or, rather, A-PAW!At the Rumpington Academy of Badgering, Lulu Whifferton-Rear is standing out for all the wrong reasons. Professor Briskwhiskers (maverick inventor and all-round jolly good fellow) has taken quite a dislike to her. When his inventions go haywire and a custard-making craze sweeps the globe, Lulu has to take matters into her own paws to uncover the truth and - maybe - SAVE THE WORLD!
