A completely mad and quirky story about bravery and loyalty in the face of evil, in which little Polly and wise man Friday O'Leary must climb Goblin Mountain and pass the Three Impossible Challenges - the Troll, the Witch and the Thing that looks like a Gherkin, in order to save the town from being taken over by the really nasty Mr Gum and the goblins.
Bursting with slapsick humour and written in an easy to read and chatty style, this book will be devoured by children who, having read the previous two books, are hungry for more about Mr Gum and all the other unforgettable characters.
