This fabulous 'reveal book' follows siblings Finn and Lucy around their home, when they have a wonder filled day packed full of monsters! The day begins with a monster crawling out of their storybook... and before they know it there are monsters everywhere... hiding under the chair and in the shower... now they are in the swimming pool! Finn and Lucy have never seen so many monsters before! They are monsters under their Dad's desk and eating his best books… even tumbling around in the washing machine. No matter how nice and friendly these funny looking creatures are, there is never going to be enough room for them in the house. They are too big, too noisy (and they look funny) AND they make a mess … AND… hang on... O-Oh!!
