Underwater Room

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. After a penguin has followed the shadow, the penguin gets in this room and can then come back whenever they like if they get the Moss Key Pin. Although there are no games to play in this room, the game Puffle Rescue leads to it.

Cave Expedition

This room was also available during the Cave Expedition. It was also members-only and there was a free Coral Reef Background attached to a rock. The background is no longer there, but the Moss Key Pin is available in the exact same spot.

Trivia

• If you throw a snowball in this room, you'll throw a bubble which will then evaporate when it touches the ground.
• Both times it was open, it had a free item. The first time in January it had the Coral Reef Background, and now it has the Moss Key Pin.
• Only penguins that got the key from Puffle Rescue can go in the Underwater Room.
• It is the second permanant members only room, with the first being the volcano.
• To get in this room you have to follow the giant squid on Puffle Rescue.
• If you were a member once and had the Moss Key Pin and clicked on the room a box would appear and it says: OOPS! To explore this Underwater Room you must be a member. We'd love you to join!
• There were many break-ins by non-members using cheating applications.
• The first time it was open, the Underwater Room was accessed by collecting the Amethyst Pin.
