"The rhyming text flows smoothly. ...Attractive double-page spreads, several of which require rotating the book to view it vertically, appear to be executed in oil pastels. The varying perspectives and unusual angles help to freshen this take on a perennially popular topic."
     —Kirkus Reviews

"This guide to all the nocturnal household monsters that create children’s irrational fears is both funny and reassuring. ...The clever rhyming text glides along, encouraging children to turn the pages to finish each stanza or find the answer to a question. ...Udovic’s use of changing page layouts is very effective in maintaining readers’ interaction with the story. Most pages are horizontal spreads, but several vertical spreads are interspersed. A terrific way to begin talking about nighttime fears with children, this book would also work well for group read-alouds."

"There’s lots of shivery fun in this debut picture book. ...[B]oth reassuring and deliciously creepy. ...Great for Halloween, but also fun the year round."
