That moment in Free For All, when in the office of the Green Dome, the inner wall revolves, and discloses a single steel door which opens into a cave beyond. I mean forget what those four chaps are doing sitting around a pulsating village guardian for a minute, if that's not surreal enough. But just where is that cave situated outside the Green Dome? There isn't one! There are buildings all around the Green Dome, with an annexe round the back, for the Butler's quarters and Kitchen area, but no cave! as for what those chaps are doing, sat round the pulsating village guardian, wearing dark safety glases - well I have to say, your guess is as good as mine. Unless it's the village guardian holding some kind of induction period!
