The Key Past The Hidden Lake

The hidden lake has a door in it that most peeps have already found but just this morning I found out how to get in. It is really simple actually. All you have to do is play the black puffle rescue and find the black puffle on the first level. then stay on the square you found the puffle on and wait for the squid shadow to pass under you. Then follow the squid shadow and land on the bubbles as you go because they bounce you up into the air. Then you will come to this green part and if you go a little to the right you will see a staircase go down it and you will see the underwater room that is what is past the door. Click the key in the underwater room and then you you can go in and out of the underwater room as you please. The photos I put were to show you what to look for. The first photo i put up is a picture of the underwater room. The second photo up is what happens when you first go down the staircase and the last photo is what the moss key pin will look like when you press on it.
