What's it like going to stay with a monster - and having a monster to stay with you? Robbie is about to find out ... Robbie is one of the first lucky children to take part in a Monster Swap: going to visit Zorb monster Voxy in his monster world. Voxy is ten feet tall, has blue fur and Amazing Elastic Eyebrows, and his favourite food is cabbage and soil burgers. Robbie doesn't quite know what's in store for him - but it's going to be pretty crazy! Illustrations by the million-selling Tony Ross make this a perfect book for young readers growing in confidence and for parents to read aloud. Read the other two books in the series: ZAINAB AND MASH and EDDIE AND FENDA.
