The distressed mother ran about the house, shouting and searching for her kids. Addressing her host, the venerable lord Randolph she said: "Randolph! Randolph! Do you know where little Rupert is? I cannot find him anywhere!"
Randolph thought for a second and then replied: "Uhhhh.... Ohhh.... Rupert? That bra, err, cute kid? Eh, I think he went... upstairs".
Poor Rupert. The sleeping poison was too hard on his young body and he died from the overdose. After a dozen similar accidents, like the maid who broke her ankle as she fell asleep, or the young son of lord Mandragore who got bruised, Lord Randolph had to settle for a regular door and sold this one back to WotC industries who patented several similar ill conceived trap doors.

What if someone already used it? When the adventurers reach this point of the maze/dungeon/house, they find that someone has already half opened the door. It is moved from the vertical position and hangs at an odd angle, leaving narrow gaps at the bottom and top. The only problem with crawling under it is the gas - it has been expelled from the door and now covers the floor in a thick layer of brightly coloured fumes (maybe even concealing the lower gap). It is a matter of wits and acrobatics to pass the trap now, without dropping into the poisonous cloud. A nasty surprise may be the body of the one that opened the door, hidden in the gasses that swirl on the ground (something to trip over). Go to Comment
Like the part about the smoke belching from the nostrils & mouths of the various creatures -- it's a nice artistic touch that would appeal to the sensibilities of the one designing this thing. Go to Comment
