What’s it like to trade places with a monster? Robbie is a slightly grubby, normal-ish sort of boy. He likes inventing new types of crisps, and his hair is far too long. Voxy is a ten foot tall, blue hairy monster of the Zorb tribe. His favourite food is cabbage and soil burgers, and he has the most enormous snout. Now Robbie is about to experience the thrill of going to visit Voxy – and having Voxy come to stay with him! He’s one of the first lucky children to take part in a Monster Swap and stay with the Zorbs in their monster world. Hang onto your bark-and-bone sandwiches! This Monster Swap could turn out to be one crazy adventure!
