Mike, Lu & Og

Mike applied as a foreign exchange student, and on a lark asked to be sent to a tropical island. She found herself dumped on a forgotten, barely mapped island populated by descendants of a British shipwreck. This island may be based on the real-life Pitcairn Island. The Castaways have "gone native" and are trying to behave like Polynesians, with varying degrees of success. Amongst other things, this explains Og's name and his dress sense.
