The Paw Patrol water-reveal activity pad offers an 8-page mess-free coloring experience, eliminating the need for paints or markers. Using the included brush pen filled with water, children can uncover vibrant colors and hidden surprises on each page. Once the water dries and the colors fade, the pad can be reused by simply refilling the pen. The activity book includes engaging prompts such as counting traffic cones with Rubble and searching for badges with Marshall, combining play with learning. The set contains one 6 x 7.5-inch aqua art pad with four sheets and one aqua art pen.
