When there is parties on Club Penguin, there are member only rooms.
i think Friday the 15th
Recently a member party was held at the night club which meant only members on club penguin could access that room. The item given away at that party was the stereo.
If you mean the one in the forest its for members only cp rocks bye
the boiler room is the only one i know of
This room is only "real" when the party Blackout is on.
There is no gadget room in Club penguin Currently.
Not really, there's only a moss key pin and an underwater room (only for members).
I dont know cuz im not a member. (ANY MEMBERS OF CLUB PENGUIN, FEEL FREE TO IMPROVE THIS ANSWER) Try googling it.
There isn't a secret room at the cove in Club Penguin
the only way is to land there on jet pack adventure (but it isn't a room, its just a landing pad), or attend the members only party that was held one time.
the boiler room in the drawer there is some old newspapers
At the 2009 Club Penguin St. Patricks Day Pary there is a hat in the Coffee Shop, an accordian in the Forest, and a Shamrock pin at Ski Mountain. *Please note that the accordian was only available in a members only room and was not available for nonmembers.
