It is a pin and you need it to open the door to the underwater room, To get it you need to go to puffle rescue ,on the black puffle(members) on the first level ,you need to get the puffle then wait til the squid starts to come across the screen then you need to follow it ,you MUST get the bubbles else you will haveto start again ,when you get to the bit where its like coral go through there still getting the bubbles until you get to the staircasey thing go into that and then you'll end up in the underwater room collect the moss key over in the right hand cornery bit and then you will be able to always get into the underwater room then. Hope that helped ,you might not be able to do it straight away ,it took me several attempts.
just click on the rock at the forest
Only members can.
If you are a member of club penguin and have a key to the door, u can go into the door at the right. Inside, there is a underwater mine that u can get gems& a new background.
go to the puffele rescue and the type what you just wrote in youtube
just click on the door the u should go in
Play puffle rescue on the black puffles and find the key on the first level
You will get the key when you have rescued the black puffle in puffle rescue three times it does not work
You have to be a ninja on Club Penguin. First, go inside the Ninja Hideout at the Dojo. There should be a sign with the fire element from Card-Jitsu on it. Click on it, and a door will pop up. Go inside it. You will be in the Volcano.
look at the instructions on the inside of the fuse box door
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.
If you mean the one by the underwater cave you have to follow the squid on the first level of rescue the black puffle there is a squid follow it and you will come to a door which the key is hidden in.
Not really, there's only a moss key pin and an underwater room (only for members).
yes,you go through to the mining place and to the hidden lake then through the squid door.(if u have the mossy key pin)
