Chinese zombies

Zombie China is is place found when you scroll way to down to bottom of the Achievements screen on the iPod Touch/iPhone version of Plants vs. Zombies. You keep digging deeper and deeper, past a worm, jewels, and a unicorn skeleton until you reach it. It shows some Zombies in traditional Chinese clothing in what appears to be the Forbidden City or somewhere in China. It is a joke about the myth of being able to dig deep enough you can dig all the way to China from the United States.
