"Wall Beings"

Taken from an email sent to Nick Harvey Jones, from A:

" Wall Beings

This is a new one for me. We can hear these guys (rats probably? maybe snakes?) in our walls in a few different locations - usually squeaks, scurrying and scratching noises. We don't really care too much, as long as they stay in the walls. Just wanted to bring this to your attention."

The "wall beings" were rats, and they stank up the joint.
