4Layer by Layer: Under the Sea explores the natural treasures hidden beneath the waves: fierce sharks, colorful fish, scuttling crustaceans, and other creatures that call the ocean home. Six interactive layered scenes with atmospheric sounds show a variety of ocean animals, with multiple layers for readers to peel away. As each layer is revealed, kids can follow the movements of the animals through the transforming scenes. On the final layer, a surprise 3-D pop-up completes the scene. Young ocean explorers will be thrilled by the sense of adventure gained by viewing the scenes as they transform on the page.
