Dinosaurs can be observed, even in zoom, from many different angles. Simply rotate the book with the reference image (indicated by the 4D seal) or the electronic device.

Animals can perform their attacking movements, walk, run or move at random.

With two quick taps on the screen of the electronic device, the dinosaur will run to the indicated location. With just a touch, he'll walk.

If there is no touch on the screen for a while, the dinosaur will perform some basic random movements. For the dinosaur to attack, just tap the animal's head.

Alert: This app combines the use of virtual images with those of books, captured by the device's camera. In view of this use, we suggest using it under adult supervision.
