Just Don't

Whatever you do, don't open the trap door under the rug behind the hidden door at the back of the pantry.
Yesterday the neighbors dog, the one that barks all night, got into the house and found the door. He was yapping at it and when I lifted it to see what the problem was, a tentacle grabbed him and dragged him down into it's lair.
Also, don't tell the neighbor that you haven't seen the dog.
