From award-winning author Andy Stanton comes book four in the "You're a Bad Man, Mr Gum!" series: "Mr Gum and the Power Crystals".Shabba me whiskers! Can it really be true that there's an ancient curse on the town of Lamonic Bibber? And you guessed it, that old roo-de-lally Mr Gum and his trusty sidekick Billy William the Third have something to do with it. But...our favourite heroes Polly and Friday and the gingerbread biscuit Alan Taylor (only 15.24 cm tall) are determined to save the town (sigh of relief). Hang on to your heads and prepare to chuckle like a chipmunk as you are whisked to the land of talking dogs, silly songs, Old Granny, and the best chase scene you've ever seen.You may even learn to say 'The truth is a lemon meringue' in Spanish! This is barking bonkers...
