Hai all!

So the other day, my step brother showed me a song on his laptop, and I really liked it! But unfortunately, I can't even remember the artist or how the song goes. All I can remember is the music video, so here is my music video description:

there was a mermaid locked up in a room, it had sex with men and then ate them. This mermaid was a zombie mermard i think, but it managed to escape from the room.

Can someone please help me! I really want to know what this song is called because I fell in love with it!

Thank you, Tabitha.
