If I find anything I'll let you know. The messing around I generally do, is because a program that is used to edit music code for another game I play has the ability to import/export Midis.
As for my friend, I relayed everything to her-her response about the water is below:
I don't know what I did. XD I saw suicune, battled the reporter guy, and then I guess Eli escorted me out of the location because after the battle I found myself outside the gate, in Heather Hill. I hadn't gotten a chance to interact with the skrelp yet, so I went back to see if it was still there. Not only was it there, but the water was filthy again too. I don't know what I did, beyond enter and exit the area.
