Andrews Dungeon of Doom

Andrews Dungeon of Doom is an unreleased den that appears to be an extended version of Cosmo's Den. It could have previously been accessed by following someone who was already in the area, but it is now only accessible through client-sided hacking.

Trivia

 * It is changed every update since it is still being developed.
 * In Andrews Room of Doom, there is a portal that leads to this room. Next to the portal, there is a sign that labels this room "Cosmo's Den 2.0".
