Where can I watch the sequel to Titanic?

The one where mermaids revived Jack Dawson from the dead, by having sex with his corpse as he sank to the bottom of the ocean. A lot of the movie takes place in the Titanic. Only this time it's under the sea, under the sea. When the sardine begin the beguine, it's music to me. What do they got? A lot of sand. We've got a hot crustacean band. Each little clam here, know how to jam here. Under the sea. Each little slug here, cuttin' a rug here. Under the sea. Each little snail here, know how to wail here. That's why it's hotter, under the water. Yea we in luck here, under the muck here. Under the sea.
