Book excerpt: Featuring a beachful of bare-bellied hippos—including one tiny baby who can only say “Bee Bo”—the Belly Button Book is a quirky addition to the phenomenally successful Boynton on Board series. Every page captivates with Sandra Boynton’s inimitable illustrations and joyful rhyming text: Soon after dark, upon the beach, we sing a hippo song, and if you’re feeling in the mood, we hope you’ll sing along: “Belly Belly Button, you’re oh so fine. Ooo, Belly Button, I’m so happy you’re mine.” Shiny and sturdy, and featuring a great (navel-shaped, naturally) die-cut cover, the Belly Button Book provides enduring, giggly, read-aloud fun. Oversized lap edition also available—perfect for more reading aloud!
