The Nightmares. Oooooo... They come in all different sizes... medium, big, humungous, Holy Sh**!!!, and @^%$!#%^&@*&^%$#@! But you need to kill them to get Zookeeper items! You'll know a Nightmare when you see one. Hopefully you'll also know enough to RUN!!! You'll find these in the Danger Dimension!
Nightmares are the only mob known to be able to take down Mobzilla. Even then, it takes quite a few of them. This is the first major Boss I decided to model all by myself. Not too bad.... :)
Use a Nightmare scale to make Big Bertha or use a lot to make the Nightmare Sword!

Just killing things, in general
How to Kill
Uh, are you sure? Really? OK. Best armor, best weapons. Hit it with a Bow a couple times, then go in for the attack. They're fast and difficult to hit. Good luck! By the time you're done, dead or alive, you'll know why it's called a Nightmare!
