Book excerpt: Froggy is going to the doctor for a checkup, and he's feeling a little nervous. "What if the doctor wants to give me a shot?" he thinks. He worries as he dresses and then he can't sit still in the waiting room. Finally, it's time to go in and change for his exam, but . . . OOOPS! He's forgotten his underwear! And that's just the beginning of Froggy's hilarious doctor visit that ends reassuringly with a gold star and a lollipop.
