This boldly coloured, striking book is full of surprises! Each page has a weird, monster-shaped black silhouette with googly eyes against a bright one-colour background. The silhouette is in fact a large, shaped flap, which folds down to reveal its true identity: children dressed up as a pirate, a cowboy, an astronaut, a princess and a monster! But could the real monster still be hiding? Find out in the funny surprise at the end!
