Only members can.
you get the pin that is by the clam
no
you open up the door in the hidden lake
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.
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.
The Hidden Lake is a room for both members and non-members. It was first opened in the Cave Expedition where you needed to have the Amethyst Pin pin to come in here. It re-opened on March 15, 2010, where you didn't need any items to get in.On the right side of the Hidden Lake, there is a door to the Underwater Room, which is open only to members. As of the Island Adventure Party 2010, there is a permanent entrance to the Hidden Lake from the Forest[1], making it not really "hidden" anymore.
You have to have the Member's Card.

If you received it by mistery gift, the door should open normally. if you put it there with pokesav, you can't.
