Category talk:Fiction set on ocean planets

What about fictions set in alien oceans but not on ocean planets?
I am thinking about Avatar: The Way of Water. It should belong in this category, but won't because Pandora isn't an ocean planet. How to fix this? I propose making this category a subcategory of a new category Category:Fictions set in alien ocean. This would fix the slight issue. Anyone has a better idea?
