The princess and the frog is an amazing story of trust, hope and true love. You surely must have seen it or read it many times so you know that the frog will turn into a prince, so you will just have to color the images with them and make them look like in a real fairy tale. You can respect the original colors, so they will look exactly like in the cartoon, or you can reinvent their look and make the things a little crazy with some new color combinations.
