Edit: It was just the Fishman mishearing the name, or it being distorted somewhere before he heard it, simple as that.
As the above states, it was just a mishearing on the Fish's part. Whatever Island the Fish says they're at, is where a chart leading to a Triforce of Courage piece is at. Timelinesplitter 01:37, June 8, 2012 (UTC)
