Sewage Conspiracy
The entrance to Hazy Maze Cave is laced with pipes across the walls leading some to believe that the room is related to the castle's sewer system. Others jokingly speculate that Hazy Maze Cave is also the castle's very own sceptic system due to the existence of poisonous gas being flatulence and the rolling boulders being large lumps of feces.
