This exciting and reusable activity book features friends and elements from Blue 's Clues & You! on four number and counting-themed reusable Water Wow! Boards. Pages in the spiral-bound book are white when dry, and reveal colors, pictures, and numbers when wet. Let the pages dry to erase, then color with water again and again! Search-and-find activities are included with each scene. The chunky-sized water pen is easy to fill, easy for small hands to grasp, and stores in the activity pad- making it a terrific travel toy. Blue 's Clues & You! promotes kindergarten-readiness, inspiring confidence, empowerment, and kindness in preschoolers as they develop their problem-solving, social, and developmental skills through play.
