Color by numbers with animals is a coloring book that little boys will find fascinating. There is a wide variety of different animal illustrations such as a smiling octopus, an amusing dog, and a brooding lion. The preset colors allow you to color each vehicle any way you like it. Selecting a difficult coloring mode will make coloring by number even more exciting. In this mode, the outlines of animals are barely discernible, leaving you guessing as to which particular animal you are coloring. It features bouncy background music and visual effects.
