One little Question

Hello everyone
Do you remember the Splash movie the one about a love story between a young man and a mermaid? It's produced in 1984. Well my question is that i do remember that it has a sequal with different leading actors. I don't have any idea about the movie's name, i thought it's splash 2 but apparently it's not because i searched a lot for it and found nothing about a movie in such name. The story of this movie is that the couple of splash (the first) are now having problem in defending their dolphin. If you do know anything about this movie, it's name or the name of the actors or anything, plz tell me because i'm desperate to watch it :(
