SCP-939 song

This is the storage that you'll reach with these elevators
They lead you to some keter pack-based predators
It's like they are guarding this place
If you get to close then they will chase
Is there something that their looking for
Besides these two, are there roaming some more?

The skin of 939 is permeable and red
and those enormous claws will easily shred
These species aren't easy to contain
tough they haven't got no brain
a spine with eye spots covering their back
So they can know and feel where to attack

How many of them have escaped with the containment breach
The method to lure prey is to imitate human speech
It sounds a bit absurd
They know your voice with one word
a bite in the skull or neck 
probably kills you in a sec
