The third title featuring loveable monster sister and brother Natalie and Alphonse! Natalie and Alphonse mostly like living in a flat on the seventh floor. They love playing drive the double-decker bed and doing roly-polies in the hall. But when the two monster siblings invent a game of wriggly worms in the jungle ... oh dear! "OW!" SHFLWUMP! That is not a good game for indoors! Will this adorably rambunctious pair ever manage to create a magical, wild camping experience in their little apartment? From the award-winning Daisy Hirst comes a story sure to inspire families to explore the great outdoors, before finding the perfect balance again back home.
