Editing Bowser's Castle

Bowser's Castle is the setting of [[World 8-4 (Super Mario Bros.)|World 8-4]] in ''[[Super Mario Bros.]]'' Prior to this, in [[World 8-3 (Super Mario Bros.)|World 8-3]], [[Mario]] battles [[Bowser's Minions|Bowser's forces]] outside of the castle. At the end of the castle, Mario defeats Bowser and saves [[Princess Peach|Princess Toadstool]]. Bowser's Castle similarly serves as the setting of [[World 8-4 (Super Mario Bros.: The Lost Levels)|World 8-4]] in ''[[Super Mario Bros.: The Lost Levels]]'', although within the sky in [[World 8-3 (Super Mario Bros.: The Lost Levels)|World 8-3]]. Bowser's Castle also appears in [[World D-3]] and [[World D-4|D-4]], on the ground. In both games' remakes in ''[[Super Mario All-Stars]]'', Bowser's Castle differs from other [[castle]]s by having thunder and lightning flashes in the background.

In ''[[New Super Mario Bros.]]'', Bowser's Castle is found rising out of a lake of lava, appearing at the end of {{id|World 8|NSMB}}. The castle features [[Thwomp]]s, [[Dry Bones]] and [[Lava Bubble|Podoboo]]s as common enemies. The ? Switches in the castle uniquely invert the floor and ceiling, including all objects except [[burner]]s. The second part of the castle features lots of lava, a Podoboo, and a [[Fire Bar]], and loops like {{id|World 4-4|SMB}} and {{id|World 7-4|SMB}} of ''Super Mario Bros.'' After accessing the boss door at the end, the player character has to battle both [[Bowser Jr.]] and [[Bowser]] to rescue [[Princess Peach]].
