well it wolud be very had because faries cant get thiere wings wet and marmaids have to stay in the water so it would be very very difficult friendship but its possible unless of course the fairy had no wings wich is possible or the mermaid wolud have to be a land walker like what the person avove me sinabi but not all of them
yes I think so. I even have seen pictures of a fairy/mermaid things on google. But I don't think that would work cause the water would probley make their wings really heavy. so it would be dangerus for mga engkanto if they were mga kaibigan with mermaids. (sorry for REALLY bad spelling Pagsulat this fast.)
Totally. They can tell stores about their different surroundings and stuff. The mga sirena could learn about land, and mga engkanto can learn about the sea. :D
