The third side-splittingly funny book in a series for very brave readers

Well, that old roo-de-lally Mr Gum and the hideous Billy William the Third are once more mucking things up for everyone. They're a-schemin' and a-hatchin' an' making their bad plans up on Goblin Mountain. And why? Because they're raising up an army of goblins to stink up the town of Lamonic Bibber once and for all! Can the brave travelers (the wise old man Friday O'Leary and the small girl Polly) make it past the Three Impossible Challenges of Goblin Mountain and save the town from a fate worse than something very bad indeed? In an epic tale of courage, valor, and plain idiocy only one thing is sure: The truth is a lemon meringue!
