Quite dangerous, but easy to kill, at least!

You're sitting alone in your house. You hear a grunt. Then more. They annoy the stuff out of you! You grab your sword, go outside and....

They're coming! You slash away. They drop something... but you might not wanna eat that.

Zombies. They are dangerous in every way! Eat their rotten flesh for a slow death. They can kill you, like all mobs. And their annoying moaning will drive you insane! Just kidding. Mostly. But it goes down easier than some mobs ;)

Some Zombie facts:

• If you eat rotten flesh, have a bucket of milk with you. That's what I will say.
• They will die in sunlight. 
  
• They are so annoying, they're everywhere!
• Like all mobs, they can't spawn in light.
• Lots and lots and lots spawn every night. Be careful!

ZOMBIES

Lots of experience with these bad boys. I once made an underground house with a friend (not the one in the creeper post) and one fell down the hole and attacked my friend. I heard grunting noises, so I thought one was above the trapdoor. When I figured out it was in the whole, I built a cage around it and killed it. And another time I killed one with sugarcane.
