Ok, so this freaked me out a little...

[Someguy]

I'm buzzing around the nether when I see... this guy. And I'm like... "who... what... wtf?"

Spoiler

That's right, a zombie pigman, in an MPS helmet. Armed with... a wrench. Of all things. Where's he going? What does he have to fix?
Film at 11.

Zisteau probably got lost wandering away from the nether hub again...

Not sure of which mod decided it was a good idea but mobs are sometimes spawned emulating your armor and tool in hand. From what I can tell they will never drop any of these either.

"mDiyo's been messing with mobs again..."

"mDiyo's been messing with mobs again..."

m-di-yo


Mmm die you.

"mDiyo's been messing with mobs again..."

The last two or three times I've been chased by a Zombie in a Modular Power Suit or a Skeleton riding on a giant nether spider I've pulled a "KHHHAAAANNNNN!!!!" with mDiyo's name.

Looks like one of Greg's new wrenches. Could POSSIBLY be him...
And is that a jetpack he is wearing?
