The little terrier from the sublimely surreal Bow-Wow Bugs a Bug (2007) has moved to board books, a format well-suited to his colorful, graphic simplicity. Here Bow-Wow tugs a “Red!” sock off a human foot, revealing an “Orange!” one and so on to “Purple!” and, finally, naked tootsies: “Lick!” In each spread, the left-hand image depicts Bow-Wow beginning to pull the sock, the right-hand image showing the sock mostly pulled off with the next-colored sock beneath it and a quizzical expression on Bow-Wow’s face. Simple enough for babies to work on the concept, weird enough to appeal to parental readers again and again. Companion Bow-Wow 12 Months Running (ISBN: 978-0-15-206558-4) is a little on the complex side for the baby half of the audience. (6-18 mos.)
