The Ninja Hideout was added to Club Penguin in November 2008. In November 2009 the entrance to the Fire Dojo was added to this room and in November 2010 the entrance to the Water Dojo was added to this room. Up until November 28, 2011 the only way you could access this room is if you had the Ninja Mask, which was obtained by beating Sensei in Card-Jitsu. This restriction was permanently removed. As of May 23, 2013 this room no longer exists, as the Dojo now has access to the special dojo rooms.
