Underwater

Underwater was an aquatic place located on the seafloor of Club Penguin. It could be accessed from a door in the Hidden Lake. However, the door was locked, and required players to enter it via a different route, by playing Puffle Rescue. Once inside, players could obtain the Moss Key Pin, and keep the door open.
This underwater room had various sunken treasure, and contained many types of corals, seashells, and other forms of aquatic life. Jellyfish and Fluffies were a common sight here.
==History==
*This room was first accessible during the Cave Expedition. Initially, no key was required to enter. The Coral Reef Background could be obtained for free here. After cave-ins at the Cave Mine, this room was no longer accessible due to the Cave Mine and Hidden Lake being sealed off. After the cave-in was cleared, this room was accessible again, although it required players to obtain the Moss Key Pin in Puffle Rescue.

==Trivia==
*Initially, non-members were unable to access this room, even if they had previously obtained the Moss Key Pin. This was changed on April 10, 2014 so that anyone that had the pin could enter the room.
*If a player threw a snowball here, it would turn into a bubble and pop upon impact.
*During the Holiday Party 2013, members with trains were able to bring non-members here, and if the non-member exited the train, they could stay in the room. Shortly after, this trick was fixed, meaning that if a member with a train brought the non-members to the room, the non-members would automatically be kicked out of the train by a key note and stay at the Hidden Lake, resulting in only member penguins, who obtained the key, staying in the Underwater room.
