Toddlers and preschoolers are little sponges, absorbing knowledge every minute of the day! Each scene in this best-selling board book series features two extra-sturdy flaps with peek-a-boo holes. Inside the flaps, you'll discover nature-related fun facts. The Baby Einstein friends introduce little ones to animals and habitats in the Grand Canyon, the Great Barrier Reef, the Arctic Circle, and more. Bright, bold illustrations are combined with real-life photographs.
