Melissa & Doug This exciting paint-with-water coloring book includes four reusable pages and a refillable water pen. Simply use the pen to color in each scene--details and vibrant color appear with every stroke! Then let the page dry to erase the pictures and fill it in again and again. This animal maze-themed book includes four animal-shaped maze challenges scenes to color and a search-and-find activity for each scene. The chunky-sized water pen is easy for kids to hold and stores neatly right in the front cover so Water WOW books make ideal travel activity books for kids.
