Ice Cavern


 * Not to be confused with the Ice Cave.

The  was a party room in Club Penguin Online during the Mountain Expedition. It could be accessed from the Supply Camp. There was a puzzle in this room, which involved clicking stalagmites and stalactite.

Players had to click either a stalagmite or stalactite, and the one clicked and the ones on either side would retract, or if already retracted, would pop out again. If a corner one was clicked, it made the one on its side retract/pop out, as well as the one directly above/below it. After completing the puzzle, players were able to access the Base Camp.

Trivia

 * Players could earn the Party Puzzle Stamp after solving the puzzle in this room.
 * After players completed the puzzle during the Mountain Expedition, a button appeared, which caused the puzzle to be solved automatically if pressed.
