The popular series takes children diving deep below the waves for some underwater maze-solving. Using their magic pen, kids will have fun finding out which strand of seaweed leads to the sea anemone, following a path of bubbles to the ocean surface, navigating through a coral reef, and locating the anchor of a sunken ship. And as they solve, they’ll learn, because every colorful page also features interesting tidbits on loggerhead turtles, hammerhead sharks, moray eels, octopus, and dozens of different fish.
