|Opened||January 22th, 2010|
The Hidden Lake is a room for both members and non-members. It was first opened in the Cave Expedition where you needed to have the Amethyst Pin pin to come in here. It re-opened on March 15, 2010, where you didn't need any items to get in.
On the right side of the Hidden Lake, there is a door to the Underwater Room, which is open only to members. As of the Island Adventure Party 2010, there is a permanent entrance to the Hidden Lake from the Forest.

On the door to the underwater there is a note:
