For the tunnel, we can assume it is used for transitions I.E. Ray leaving and other similar things. However, it could be theorized that the end is for the last Minecraft Let's Play. In episode 111, around 27:02 you can pause and see a long tunnel with stone stairs at the end. This implies it leads to some sort of room or another tunnel, which leads North. Not much is in that direction (if it is directly straight) except for maybe Shooting Gallery, Altar of Pimps, the Lake of Pimps and the mural of Dan. One unexplored option is something under the Lake of Pimps. Odds are though, they are lazy and it leads to A. Nothing, B. a Mine or cave, or C. a room/just the tunnel created by Geoff/Gavin for the joke of noone being allowed in.
