The Grunt and the Grouch are two of the most disgusting and badly-behaved trolls in the world - and the most fun! They keep bogies and ear wax in jars, and they never, ever have a bath! This brand-new series of three-in-one storybooks will bring out the troll in all girls and boys! Dive in with The Grunt and The Grouch as they gatecrash the opening of the local swimming pool, get all tangled up on a camping trip and come face to face with a little troll horror when they're left to babysit Grunt's mischievous cousin.
