| Temporary Room
This room was only temporarily found on Club Penguin.
The Stair Dimension was a party room used for the April Fools' Party 2011 and April Fools' Party 2012 on Club Penguin. Everything is upside down except for usernames and messages. This is the only new dimension from the April Fools' Party 2011 that has brand new music as all the dimensions' music last appeared in either 2007 or 2009.
During the April Fools' Party 2011.
