the flaps are great, way less intimidating than a pop-up book but with the same amount of fun interactivity. pop-up books always used to stress me out when I was little because I was afraid of tearing them, or they would fold up wrong and get all crumpled, and my tiny brain wanted them pristine and magical forever. the flaps are durable! the bait-and-switch when I guessed that "mare" meant "ocean" because it was next to a whale lol
