I'm trying to remove Finland from this map and replace the area with ocean. What would be the easiest way to do this? I can't seem to select the surrounding countries and layer mask. If this sounds like a strange request, it's for a conspiracy theory night my friends are having. I'm making a powerpoint on the topic of Finland not actually existing and that it was made up by the Soviet Union and Japan to bypass conservation laws when it comes to fishing.
