We did not finish this book. It was a silly story, which in of it's self is not the point. But to read this story and enjoy it you had to stare at a dot for 10 seconds and then look at another dot and supposedly you would see the same picture in a different color. It did not work for us and without that the story did not make sense. Maybe if you have perfect vision this might work for you! I say it's pretty hard for younger children to understand let alone "see".
