you have to beat all the levels in the the black puffle rescue then when you beat it take the key when you find it and go to the hidden lake. click the door and your in. I've never beat the black puffle rescue before but i know how to get the key.
play the whell-bot mission- he'll bust open the door if you do the mission right.
With your puffle, you throw a puffle o through the puffle door.
You will get to access the place behind the door in the Mermaid Cove.
Only members can.
b uy a blue puffle then touch the black thuing onn the door
go to the puffele rescue and the type what you just wrote in youtube
What you have to do is you have to get a key from Gary and then go to the door and unlock it with the key! but choose wisely, or else you have to get another key from the drawer!!
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
be a member and go on black puffle rescue get the key and unlock the door /this may take a while/.
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)
