Missing key in MM&M room 14710

[zipwin]

Thanks all, I finally figured it out and am so relieved to be out of the spider mazse! Clever solution....I have raced onward to a seemingly easy room-16523-with a red key in the wall halfway down a ladder on the right. Have figured out how to get the money above the red door but cannot get the red key...looks sooo easy and Jack's head actually touches the key when he jumps up but it stays put. Is that right? I'm stuck here and can't go back up because I can't jump the barrier in the room above-16323.
