Dungeon 7?

[nahneun]

Hello all, I found the Iron Key but I can't figure out how to get to the door that uses that key. I know the two places you can fall from lead to the Wooden and Stone Key entrances. Any help would be greatly appreciated Thank you!

You did the puzzle with pushing blocks in the Great Fairy cave in that hill?

Ahhhh yes, I did but I left after I got the heart piece. Thanks! I didn't know there was a door there ;
