- I guess because Bowser is the King of the Koopas, he has to be head of a kingdom. Though I do think that a kingdom is a place and not an organization. - Cobold (talk · contribs) 14:59, 25 May 2008 (EDT)
The places as: Dark Land, Bowser's Magma Mountain, Bowser Land, Bowser's Gnarly Party, World 8 (New Super Mario Bros. Wii), Bowser Badlands, World 6 (New Super Mario Bros. 2), The Lava Pit, Bowser's Castle, Grumble Volcano, Bone-Dry Dunes, Chaos Castle and Bowser's Kingdom it's probably the Koopa Kingdom locations. Because it has a lot of volcanoes spouting lava, dark ambience, thunderstorm, wasteland filled with bones, castle ruins, dead trees, ashes, fire embers and Bowser's images. Even in other languages show, for example: クッパ王国 (Kuppa Ōkoku) and クッパの国 (Kuppa no kuni) and Regatul Koopa.
