** Children's Technology Review Editor's Choice

“OOPS…” Blue Hat, Green Hat, Sandra Boynton’s famous and funny book, comes alive with sound and zestily ingenious interactivity. This wonderfully clever digital book app will surprise kids and grownups alike. Turkeys may also enjoy it, if they can ever figure out how to turn the dang thing on.

Three earnest animals and one misguided turkey learn colors and clothes. Though admittedly, the turkey never quite gets the hang of it.

“I have a particular fondness for Blue Hat, Green Hat. At age three, my son Devin had a surprisingly hearty laugh for a small person—a laugh that would make everyone else laugh. I created this book long ago specifically to elicit that belly-laugh from him. It was great fun to re-invent this book as an interactive e-book app, collaborating again with my endlessly clever Loud Crow friends. The digital dimension gave us so many terrific opportunities for adding theatrical flair to this spare yet decidedly Vaudeville book.” - Sandra Boynton

Far beyond any e-book experience, the Blue Hat, Green Hat interactive book app has all the magic and appeal of a traditional pop-up book, offering lively interactivity and nifty discovery.

The third Sandra Boynton book app, all of them created in collaboration between Boynton Moo Media along with the award-winning developer Loud Crow Interactive. Blue Hat, Green Hat follows their wonderful top-selling debut, The Going To Bed Book app, and the glorious bestselling Moo, Baa, La La La! app

Not as good as other books :(

The first book was good, the second book was absolutely amazing and this one was pretty average :(

I was really excited when I saw it in the app store but it is actually quiet boring compared to the other books.

I would have loved to give this book 5* like Moo Baa Laa!

Son laughed and laughed

My son loved this story in hard cover but the app made it so much more exciting for him. It hit the right funny bone, he could not stop laughing.
