A lot of them are just like normal people. They have fins and some of 'em look weird, but things aren't too much different.

I don't think it was TOO well hidden though. It's just really tough to get there. [Like all islands filled with beautiful mermaids or something.] Nah. The last island I visited was this cool one where half of it was cold and the other half was hot! It's called Punk Hazard.
