if its on the black puffle rescue you have to go and get the black puffle and wait until there is a shadow when you have seen the shadow follow it but you have to keep changing but you have to keep going in bubbles when you have done it leads you to the underground water thing and then you get the moss key and then youhave finished the black puffle rescue .
in puffle rescue, if you choose the black puffle to rescue, then in the first thing, there is a big squid like thing. follow it. if you go in to the bubbles when they pop, you will stay alive while following it. it will bring you to a green thing, go in and through it. there will be an entrance, go in that. it will lead you to the water room. then you will see the moss key pin. that's it.
You have to play puffle rescue (black puffle game). Then save the black puffle but stay there.
Then follow the big shadow using the air bubbles to stay up until you reach the secret island-thingy. (This part might be wrong because I did it a while ago): go up, left, down and left and you should see a staircase. Go gown it to the secret room and pick up the moss key (it's really a pin).
If you mean for the game 'Puffle Rescue' in the Mine, follow the squid in level one and try to float on the bubbles.
This won't get you banned, it was mentioned in a Club Penguin blog I read somewhere.
You have to play black puffle rescue but you have to be a member
You need to be a member and play the puffle rescue game and it has to be the black puffle. you need to complete the black puffle rescue game and you will receive the key. In order to use the key you need to be a member. This worked for me and I hope it works for you :-)

You will get the key when you have rescued the black puffle in puffle rescue three times it does not work

On the black puffle rescue get the puffle and wait there until you see a squid shadow and then follow it but keep walking into the bubbles so you don't sink and then the shadow will lead you into a secret place and find the key! that's all
Play the black puffle rescue and follow the Shadow of the octopus and then you are in the secret room and you have the key.
