Book excerpt: Going to dolphin school under the sea is a magical experience for Pearl and her friends! It's time for dolphin school's annual Show Off Day! It's a chance for students to perform what they've learned for the whole dolphin community. Pearl and her friends Echo, Splash, and Flip are excited to come up with the best group routine ever! But they all have different interests, and they can't agree on what to show off. Can the dolphin friends come up with a compromise, or will they end up looking silly in front of everyone?
