I think I got stuck, can't seem to get the key next to the root in the forest, tried to follow the steps from the comments, but for some reason it won't let me take the rupee from jeane's shop even though I have her love at level 2. Also, where can I find the wire?
Wire is in the cash register in the food court. Need the knife and Int level 1 I believe. That quest is probably what's blocking you from progression. you'll need to have started the task singing stone before the root hand gives you the proper prompt. That'll start after you're done with the elevator.
