Behind the door lies a hidden room called the underwater room in Club Penguin. Many girl penguins like to play "mermaids" in this room. There is also a pin in here called "moss key'' pin.
he is so joking. maybe he said that because there is treasure there. the real answer is that behind the door is a secret room. there is also a free pin. it is the key that you earned as a pin. when you click on it. it is called the mossy key pin
you get the pin that is by the clam
you open up the door in the hidden lake
Not really, there's only a moss key pin and an underwater room (only for members).
you dont need one :]

You go to the nighclub. go up to the games room ( i dont know the name of it) play one of the games im not sure which one. after you completed the game you will get the key to the door in the hidden lake
The stage door is hidden from view behind large security gates on Deansgate.
