This Spanish animated movie, with all the dialogs in rhymes, shows the misadventures fisherman's town menaced by an Unicorn from under-the-sea and a gang of monsters like a vampire and a mummy (¿¿??). Marina, a little girl, and the kids of that town, try to solve this big trouble.
This animated movie reminds me a very old cartoon movie from Australia named Dot and Keeto (1986), with talking animals interacting with children.
I gave this movie 4 of ten stars only for the catchy songs played during the movie, but it had an early 80's animation style and a very, very weird plot line. Could be a little entertaining, I think.
Just a nice try.
