Forum:Hyoomen Evolution?

When the Hyoomens took off their hats at the end of "Susan Strong", we saw that they were just fish people, though Susan's species is still unknown ( most agree she's really a human ). But enough about that. We know that Hyoomens were really humans but what on Earth happened to them that they suddenly developed gills and fins? Was it some sort of toxic waste? Magic? Or some kind of freak evolution junk?

I--I know it's stupid but...answers please?
