Boo! Here comes a frighteningly fun Halloween follow-up to the popular Twelve Hidden Days of Christmas. Through the first haunted doorway, I peeked right in to see… a bat hanging from a crooked tree. What could be in the other 11 delightfully creepy rooms? Hidden throughout this spooky house are more than 375 items to find, including 30 monsters leaping, 36 zombies dancing, and 40 werewolves howling. A double gatefold at the end provides a vast landscape that's twice the length of the picture book!
