Have a green thumb (Plants Vs. Zombies)
Getting ambushed by a coordinated group of mindless zombies? Plants Vs. Zombies is the perfect app that provides a list of useful vegetation to defend against the undead. Not only are vegetables good for you, but they can also ward off icky zombies. Try a row of fist flailing bok choy, and checkerboard some corn. Add pea-shooting plants, and the only green thumb you will need is to shovel dead zombies off the lawn.
