There are many Ben 10 Apps which are downloadable via the app store for iPhones, iPod Touches and iPads.
Ben 10 Mouth-Off
The Ben 10 Mouth-off app is where you see an Omnitrix, you turn it until you see the hologram/silhouette of an alien you like. You tap it, and then the mouth of the alien appears. Hold the device to your mouth, and it looks like you have the alien's mouth. Using the iPhone/iPad/iPod techology when noise is made into the backside of the Apple device, the mouth moves accordingly. Includes Ben, Stinkfly, Grey Matter, Blitzwolfer, Perk Upchuck, Wildmutt, Cannonbolt, Four Arms and Diamondhead. The Lite version includes Upchuck only.
