Clock Town from Majora's Mask 3D, when I played Majora's Mask 3D, which was before I played Splatoon 1, I was envisioning certain areas of Clock Town being covered in ink. That was probably because I really wanted to play Splatoon 1 as it was the only game of the series at the time, but I decided that I should 100% Majora's Mask 3D first so that I could play Splatoon 1 without looking back.
Also, in terms of layout, it's a great stage to use for Turf Wars, it has a big open space with multiple ways to advance and the best part is, it has parts that can lead players away from the fighting so you won't have to splat the other players to escape being splatted if you're at a disadvantage.
