The Iceberg is a hidden room in Club Penguin. It is shown on the map, but is unmarked. Here you can play Aqua Grabber, which was added in February 2008. Penguins like to have parties in this room to see if they can tip the Iceberg, which was started by an old rumor in Club Penguin. On April 5, 2013 background sound effects were added to this room.
