Join Dog on an adventure to a fancy-dress party. But what costume will Dog wear? Simply pick up the brush pen, paint the magical pages with water, and find out! To bring the seven adorable pictures to life, just add water to the magic painting pen and paint over the white spaces on each right-hand page. You'll gaze with wonder as color magically appears with each brush of the pen and hidden pictures are revealed. With pictures to discover in every scene, children can color in the pictures with the magic painting pen included in this book. Using the book is super-simple. Just unscrew the pen tip, add water, then screw back on, and your pen is ready to use! The book is 100% reusable too, with specially designed pages that can be used again and again. Once the water dries on each right-hand picture, you can paint the pictures again! Designed specifically for little ones, this book boosts learning development of first experiences all children will encounter and is the perfect introduction to water painting fun.
