"Mad scientist Doctor Daffney has an unusual garden. It's full of oddly-shaped trees. When Katt the dog goes exploring, Boffin Boy and his friend Polly follow Katt into Daffney's garden. But they don't call Doctor Daffney a mad scientist for no reason. When Boffin Boy and Polly are captured, things start looking pretty grim for them. And Daffney's secret laboratory is every bit as weird as you'd expect."--Back cover.
