Squelching from under the coffee table, a pile of goo raises what could almost be called "a head" in a slightly sibulent voice, it speaks...
"Hello Altronomy, Welcome to this place of semi-madness... Make sure you leave your sanity in the bucket, it could mutate, and then I'd have another me!"
Its 'face' splits into a huge grin, "Be nice to things that live under the bed, never annoy the witches, and watch out for Sock... he has a big club, and he's stupid enough to use it!"
The blob oozes away, fondly stroking the bucket as it passes it.
