is there a movie of mermaid 4?

Well there is The Little Mermaid original), The Little Mermaid 2: Return to the Sea (It's all about their divorce- I MEAN MARRIAGE!) and Little Mermaid: Ariel's Beginning, but so far there is no sequel of the sequel's sequel. (4th movie) Even though there is that direct-to- direct video of it in Youtube, it's fan-made.
