"Bam! Bam! Bam!"
"Eeeeek! Eeeee! Eeeek!"
Imagine a 4-year-old reading a storybook, touching an onomatopoeia word and the sound blasting off the page.
That's the reality of the new interactive, iPad version of Tucsonan Chris Gall's "Dinotrux."
The digital publication offers a three-dimensional view of the menacing bullies - part-truck, part-dinosaur - that rumble and bulldoze their way through prehistoric Earth.
"It's an exciting addition to the book itself," Gall says.
IPad versions augment picture books and help the books keep their relevance, says the author and illustrator, noting that many 4-year-olds have access to an iPad.
Gall says the iPad version keeps the spirit of his book, the key is "finding the right balance."
Creatures move, rain falls, and lava and rocks spurt while prehistoric- and urban-jungle sounds leap from the page.
When the iPad is tilted, slight 3-D views kick in. Kids also can create their own "Dinotrux" version.
"Dinotrux" also is in development at DreamWorks to become a 3-D animated film.
