It is a temporary room for certain parties/events in Club Penguin Rewritten. It may or may not return in the future.
The Underground was a party room in Club Penguin Rewritten that was added during Norman Swarm Has Been Transformed at the Stage. To find it, five penguins need to stand on a pattern of X's near a boulder, and at least one must wear a bug costume.
