Finding fun things for a young child to do on a long car ride can be a difficult feat. With the Water Wow! - Animals, your son or daughter will have the perfect thing. This book, made for ages 3 and up, features 4 different boards for your child to color in. But the cool thing about this set is that it is no ordinary coloring book. The book comes with a refillable water pen. And when this pen is applied to the boards, it creates the different colors for the items. And when you let the pages dry, the colors go away and your little guy or girl can do it all over again. The pen is stored directly in the front cover of the book, to ensure that it is not lost. And because it is just water, it is very difficult to make a mess out of this fun toy.
