This is a fun book where you push, pull and slide to see what the magical rainbow has done.
Abams Appleseed sent me a copy of this book to read for review (thank you). It has been published and you can get a copy now.
The tabs show you the rainbow, change the spots on the dragon, and create different colors on the mermaid and the merman.
Just make sure the child doesn't get too rough with the tabs and the book will last a long time.
It is magical!
