at one point in time there were some ideas floating around about having Netherbelly prisoners hanging around the stage on the sides. There were even some sketches and such that showed what the game designers were hoping to do, which was to have these prisoner guys strangle you if you got too close.
Now i have seen that the Prison stage is alread doing this, and maybe they opted NOT to use it in the netherbelly as it would get redundant.
Does anyone know?
