Mr. Gum and the Goblins

Old roo-de-lally Mr Gum and 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. Can the brave travellers make it past the Three Impossible Challenges of Goblin Mountain and save the town from a fate worse than something very bad indeed?
