Let’s face it. Dorothy Gale is a stone-cold killer. She effectively bludgeoned a woman to death with her house, and then melted another down into her component cells. If she’s allowed to run across Oz unsupervised, she will kill again. That’s why you need to play The Wizard of Oz for Facebook. Dorothy will be so busy bossing around the Munchkins and rebuilding the Yellow Brick Road that she’ll forget about her bloodlust. For a time.
