It's time to go to bed, and the monster is about to crawl under the bed. Sleeping in bed is only good for children, those stinking creatures who are terribly noisy when they snore. He invites the child readers, whom he assumes are monsters like him, to join him. But... Are they really? And is sleeping in a bed really so horrible? After Are you a monster?, the author and illustrator Guilherme Karsten offers us this second interactive album which is just as enjoyable.
