Strange SMP6 wild things

I was in the smp6 wild and all of a sudden in red letters in the chat it said "The ground shakes nearby..." should I take caution, is it a bug, or a new thing in update, or awesome EMC scaring people. Let me know!

ICC is angry at us, he makes the ground shake.

It's a new thing in the update, be careful though, don't know whats going to pop up around the corner.

Like Ahzeriel said, it's part of the new "Survival Update". There are going to be heaps of unexpected surprise in the Frontier/Wild.

That means there is a giant nearby

We'll come kill it for you!

well, i was on and then there was a giant zombie about 12 blocks high and 5 thick, im scared. U cant harm it either

also, is anyone else kicked from minecraft now

me is scared for survival update =O

Minecraft.net is currently offline.

No-one can connect. EMC staff can't fix this problem.

Oh that explains a LOT of things =D

I lagged, turned around, and this thing called an "Enraged Skeleton" popped up. next thing I know, I'm at 2 hearts and it's in my face, I got some hits on it, though. Then I logged out, because it freaked me out, and I never read about the updates xD
Anyone else fight one, and is there some "Weakness" to them, so I don't die the second I log back on?

Go Survival Update

Run?

I believe you are invincible for a couple of ticks so try to run away and box yourself in. Regen, then kill it.

Thanks, I'm going to try it now, wish me good luck.

Update:
I died xD
Good thing I had nothing big on me. Thing is, I respawned in the bed of somewhere farther from spawn than where I was already. I was lost to start with, no I have to go farther xD

has anyone here met an enraged creeper yet? i know i have

I've met two.
