I concur that this is an interesting connection you've observed that I didn't notice before. I was trying to think of some other possible names of places or important items on the island that might follow a similar naming convention, but nothing immediately came to mind. The closest I could come to something like that was "Bottom of the Island" from Wind Fortress, and I was thinking about making some joke about it being "the island's ass," but I couldn't think of a way to make that joke that wouldn't have come across as ridiculing the OP for starting this thread. If only Captain Fabulous was here.
