Down below the waves, where mermaids play: that's where this captivating "Step Inside" transports young children. As kids turn the pages, they'll travel across the ocean floor, with its layers of plants, shells, fish, and even sunken treasure. But they'll also learn what a mermaid's life is like as she attends school in the ocean; enjoy fun and games in the Pearl Palace, where all the oysters live; help decorate the underwater garden with shiny glass; peer into the Little Urchin Nursery; and celebrate the spring tide with a ball.
