This exciting activity book includes four reusable pages and a refillable water pen. Use the pen to fill in each activity, from coloring in counters to tracing numbers, and see hidden colors and pictures appear with every stroke! Then simply let the page dry to erase the pictures and fill it in again and again. This animal-themed book includes four 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 and travel toys for kids!
