Straight from the Jurassic Park movies in this app stuffed Dino Gröhlereien. Together with the cinematic background noise and / or -Music. My son (4 years) is the app great, I'm not really so excited. Is halt 'n Soundboard. Oh well. But who knows !? Perhaps you can hear the idyllic forest walk times a strange roar. Since the app can then still be of great benefit. "Was it a Zilp-ZALP or a T-Rex?" ;)
