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 hilarious series of three-in-one storybooks will bring out the troll in all girls and boys! Buckle up with The Grunt and The Grouch as they dare each other to go on the loop-the-loop at the fair, help themselves to one of the museum"s dinosaur bones for Grotbag"s dinner, and fall out so badly that they have to split the house in two.
