I would like to know your area and cave design ideas? I think another wintery area would be good- more like a mountain though, a desert area, a rocky canyon area or rocky cave, a lush tropical forest with exotic creatures and pikmin, a mountain or high up area maybe where we meet pink pikmin? A more complex aquatic environment? A sea cave and a cave really dark sorounded by strange fungi and flora of which some glow to help you see? A clockwork cave, a coral and seabed like cave or tropical sea environment, a volcanic area or cave- maybe last area or cave? I think the last cave would be a mixture like last time. That's off the top of my head- what about you?
