| Temporary Room
This room was only temporarily found on Club Penguin.
- Not to be confused with the Ninja Hideout
The Ninja Headquarters was a party room of Club Penguin  for the Card-Jitsu Party 2011 and 2013. The Fire Training Plates and Water Training Plates were available on this room in 2011. The room became available to everyone at the Card-Jitsu Party 2013.
There's a glitch that if you access the room by a special link, log in and choose a server, before entering the room, instead of saying "Loading Ninja Headquarters", it actually appears as "Loading Haunted House Entrance", the room added for Halloween Party 2010 and Halloween Party 2011.
During the Card-Jitsu Party 2011
