*Laughs* I mustv'e seen a million topics debating how Blitzball players can breathe under water.
Did...it occur to anyone that the water is not pure?...because it isn't.
Notice the black myst when going inside a Save Sphere?
Yeah, I believe there are some chemicals in the water that make it more breathable, kind of like a semi-balanced substance that's not too dense...and it couldn't be, judging by how fast players can actually move in it.
Two birds ith one stone, right there. Makes sense, doesn't it?
