A Secret Room is a room that is hidden via the map or a room that only certain penguins can access. For a room on the Map, no subtitle is available when hovering the mouse over its proximity area. However, people will usually know if they are hovering over a secret room if their cursor changes to a pointing finger. Since the Map update, the Iceberg remains the only secret room available via the map. There are other secret rooms that aren't on the map.

 Iceberg's Secret room status
The Iceberg is a secret room because a subtitle is not available when hovering over it. However, it is very populated and so much is known about it that people are puzzled over it being referred to as a hidden room.
The Iceberg also has the game of Aqua Grabber on it and in some festivals there is a firework display.
The Iceberg is accessible through your EPF Spy Phone, despite being a secret room.

 Former Secret Rooms
