Creeper:

I'm a Creeper and I'll blow up in your face,
All you do is move things, from place to place

You call yourself scary? [bad word] please you trippin,
Blow you up from that cave, to the house that you live in,

You stole one block? I destroyed the whole thing,
I'll kill you and get experience like dingding, da dingding

I'm lean, I'm green, I'm winning like Charlie Sheen,
I'm the best mob in the game, [bad word] I'm the best mob you've ever seen,

Last week I stole your girlfriend, She said "Finally I'm free",
But I wasn't the one blowing up this time, because she was blowing me.

Enderman:

I'm from you're worst nightmare, you should be scared,
Cuz I'm over here, now I'm over there, and I'm over here..

 [bad word]  I'm everywhere

I've got Ninja like skills, You don't even fight,
I'll keep you terrified yup all night, that's right

I dodge arrows like Neo, [bad word] suicide,
I agree if I was you, I wouldn't want to be alive,

 [bad word]  I'm gonna take your life,
So hide your kids and hide your wife,

You'll never get laid, you're too much of a wussy,
Plus you get scared every single time you see a [bad word] 

Creeper:

Enderman you're not tough, Don't even bother,
At least I'm not scared of a bucket of water,

Your scare tactics are weak, [bad word] is cheap,
You're like a tall version of Urkel, the geek,

I may be scared of cats, but your Girlfriend still calls,
at least when I die I don't drop my balls

Enderman:

I'm the new fear Creeper, bow down and call me Sire,
You're one of the oldest mobs, maybe it's time you retire?

People get scared stiff when they see me walk by,
Look at me in the eyes, and I'll make you cry

Your rhymes are weak Creeper, so slow it's like you're laggin,
Now get out of here before I call my boy, the Enderdragon
