I love the new rooms and the Cave Expedition! Club Penguin has seen a lot of creativity lately and love that every one's having a great time exploring. Club Penguin has confirmed that the Expedition WILL end on Thursday...
As for the Night Club thing, Club Penguin said to take your friends to the Night Club on Friday... What could this mean? Possibly an update? Wait a minute... Isn't that one boom box in the Night Club lead down to the Pool? Well maybe it means that the OTHER boom box will lead to the Mine Cave! LOL! I don't know but if you think you know post a comment with your theory.
There are three new catalogs! Check out the cheats for each of them:
