Underwater

Underwater is an aquatic place located on the seafloor of Club Penguin Rewritten. It can be accessed from a door in the Hidden Lake. However, the door is locked, and requires players to enter it via a different route, by playing Puffle Rescue. On the door there's a note on how to get in. Once inside, players can obtain the Moss Key Pin, and keep the door open. After obtaining the pin, it disappears from the room.

Trivia

 * The room is never decorated for parties.
 * In Operation: Blackout, the room was renamed "Klutzy Reef" by Herbert, and the tour guide description was changed as well, being read by Klutzy.
