Another entry of the iStoryTime series has landed in the iOS App Store, and this one immerses children in an adventure with the heroes and heroines of Cartoon Network’s Ben 10 Alien Force animated series.

Ben, Kevin, and Gwen are called in on another mission to help save the Earth from alien invaders. Plumber trainees Manny, Helen, and Pierce find out about the assignment and request to be involved, hoping to prove they have what it takes to be a true member of the Plumbers. Will it be a fight to the finish or will they learn to work together to conquer what awaits in the Blackrock Mountains? Find out in Ben 10 Triple Threat.

The app has three ways to experience the story: “Read it Myself” allows reading and viewing the material in the same manner that traditional books would offer, “Read to Me” highlights each word as it is professionally narrated, and “Auto Play” adds narration but also automatically turns the page when it is completed. This is a nice feature for very young children, or to just make the experience a little more like a movie.

Ben 10 Triple Threat – Children’s Book is a universal app compatible with iPad, iPhone, and iPod touch running iOS 3.0 or later, and available in the App Store for $1.99.
