The Underwater is a special members-only room located beside the Hidden Lake. It can only be accessed by following the Giant Squid's shadow in the game Puffle Rescue or by using a special link. After a penguin has followed the shadow, he or she enters this room and can then come back Moss Keywhenever they like if they obtained the Moss Key Pin before it was removed. Although there are no games to play in this room, the game Puffle Rescue leads to it.
- This room was first opened as a members only room during the Cave Expedition. There was a free Coral Reef Background attached to a rock. The background is no longer there and has been replaced by the Moss Key Pin, which is available in the exact same spot. The room reopened on March 15, 2010 and is only accessible by members.
- Today most players don't go to this place, since they are not a member, or they don't know they have to obtain Moss Key Pin in order to re-enter the room.
- When the mermaid suits were available, most people pretended to be mermaids, which made this room popular.
- There was once a background here, and it was replaced the Moss Key Pin which was removed for the Underwater Expedition along with a pearl and the fish. These were however brought back soon after.
- If you throw a snowball, it turns into a bubble which pops upon landing in the target.
