"Scribble"
Keep toddlers busy on long car rides with games like Scribble, where kids use their fingers to draw right on the mobile screen. Shake to erase and then start all over again. If that fails to entertain, try BugSquash, where you tap the touch display to smash bugs as they race across the screen. The more bugs you squash, the more points you receive. Upload your own background pictures and flatten all types of insects including beetles, spiders and even bed bugs. (Scribble FREE/BugSquash $.99)
