Moo, Baa, La La La! - Sandra Boynton, by Loud Crow Interactive Inc. - Sandra Boynton’s best-selling book of all time comes alive with sound and movement and gloriously unpredictable interactivity. The wryly inventive Moo, Baa, La La La! digital book app will intrigue and amuse little kids and big people alike, and perhaps even elicit an appreciative snort from the occasional uninvited rhinoceros. This is the second digital book project for the team at Loud Crow and Sandra Boynton and it's perfectly amazing. Far beyond any e-book experience, the Moo, Baa, La La La! interactive book app has all the magic and appeal of a traditional pop-up book, offering lively interactivity and nifty discovery. Of course, you can hear each animal make its unique sound. (In some cases, VERY unique.) But there’s more! Help the perplexed chicken stagehand raise the curtain on a stage full of dapper dancing pigs. Turn day to night with the touch of the moon. Slingshot the running cats away from the barking dogs. A touch of the duck activates a quack which brings in another duck. And another. And another. Even the back cover has a curiously articulate spokesman that you really mustn’t miss.
