you have to be a member to get the key......go to the mine and play puffle rescue with the black puffle.....on level 1 get the puffle and wait there....you will see a squid ..go on the bubbles it produces onto the island ..go through the door in the island.. you will find yourself in a room .then you will spot the key ..pick it up and go to the hidden lake and enter ... you will find the room
You have to be a member. Go to the mine, and click on the 'Puffle Rescue' game. Click on the black puffle mission. When you see the squid, follow it, and stop yourself from drowning by going over the bubbles when they pop, and it should take you up. When you get to a maze of coral by following the squid, search around, and you'll find a key. Get it, and exit the game. Go to the hidden lake, and the door should now open.
