Ever since the Ship Hold opened, penguins have made attempts to find the Key to this room. They have claimed Rockhopper's Key to be virtually anywhere on Club Penguin, from underneath the Iceberg to inside Rockhopper's hat. However, Rockhopper has stated several times that he keeps the Key very close to him at all times. When the Migrator sank, he apparently escaped with the Key on his lifeboat. Penguins everywhere still hold the belief that Rockhopper would unlock his Captain's Quarters someday. The Penguin Times confirmed that the new room that came out in April 28, 2008 was his cabin. The newsapaper also confirmed that Rockhopper was opening it as a reward for rescuing his ship, provided they can find the Key. According to Rockhopper, when his shipsank, he had thought his ship was gone for good. To thank us all for our work fixing his ship, he was going to let us into his Captain's Quarters. Quoted from the Penguin Times (issue #132), he says: "Tho' it be me place for thinkin' n' countin' me treasure, ye have all proved yourselves a trustworthy crew by fixin' me ship."
A trick can be used to access this room anytime. If you login using the link Captain's Quarters start, you can access the Captain's Quarters while Rockhopper is not in Club Penguin. However, this doesn't work anymore.
This is the only place where you can play Treasure Hunt, which means it can only be played a few times a year.
There is a Card-Jitsu card featuring the Captain's Quarters.
