This book has lots of humour and rhyme, making it perfect for EYFS and KS1. The context of monsters wearing different types of underpants is hilarious and silly, which makes the book fun and engaging. This may help children who are afraid of monsters at night, good for PSHE. The pictures are bright and eye-catching, and the monsters differ in features and colour, some monsters have 1 eyes others have 3. The setting of the world of space that the aliens inhibit is similarly vibrantly portrayed, for eg, at the bottom of the monster ocean or in a monster disco. This fun visual element of the book keeps children engaged. By the last page, children listening to the story can feel safe, when the two children in the story look for a monster under their bed to find nothing there, and at the side of the page they can see a small funny monster running away with underpants.
