Abomination Zombie

1 'ABOM-ZOMBIE'
"Zombies. Despite actually having a brain, and I am not talking about the one in
its mouth, CAN YOU STOP EATING YOU USELESS FAIL-RAISED NUMBSKULL, they seems to
be rather brain-dead. Maybe they are. ARGH, STOP DESTROYING THE FURNATURE YOU...
(a loud zapping noise can be heard followed by a sharp fizzling noise and a THUMB).
Err, where did I come from. Yes, zombies. They like brains. They eat brains. But
don't count on them having one. If they had one they would eat it. And eating
brains make them quite noisy and aggressive.
And when they are many, they actually work together. Like a fighting machine of
flesh and well-consumed brains. Yes."
