You need a strong stomach for this week's best iPad apps. We're giving you a zombie-fighting game, an anatomy reference, and more. Hope you don't lose your lunch!

Dr. Seuss's The Cat in the Hat Color & Create:
Who wasn't a Dr. Seuss fan as a kid? Now little ones can enjoy the classics on the iPad with a coloring book based on the PBS Kids TV Show The Cat in the Hat Knows a Lot About That (which also just launched on the iPad). $1.99

Anatomy and Physiology Revealed:
This app's not for everyone, but if you're a biology major or a pre-med student, it might be helpful to have around. You might not have your own cadaver to dissect, but you can turn to this app to see the insides of the human body, including skeletal and muscular systems, the nervous system, the cardiovascular system, and more. $49.99

The Walking Dead: The Game:
I have a recurring dream that I'm being chased by zombies. It's probably due to watching the Walking Dead TV show. In this game you can take out your walker agression,
smashing the creeps trying to catch you, all while trying to survive the end of the world. $4.99
