It was a game that had the blonde girl with the blue top you had to look after who turned out to be super voracious, it was a point and click with a huge amount of secrets like tell tale games a bit... To the point you press everything on the screen like a shop in the background would lead to another experience. If i could describe it in this game would be a cave in the background of the moving screen as the mermaid swims if you click it it goes to a cameo where she eats echo the dolphin. And goes through the Same game for a while. Or a passing boat or cruise ship you could click on where she could climb aboard and sing to people she could eat.
It's ok this is about this game which is great so far. Yeah I have the gold mermaid moving I'm not sure what she does it's an unlockable skin?
