Nick's New Mario World: Lemmy's Castle

This castle is a scale model of the first rooms of the first fortress in world 5 from SMB 3, the first room of the first fortress of world 6 in SMB 3, and the first room of the second fortress from world 7 in SMB3. The second room is a scale model of the second room in the first fortress in world 6 of SMB 3, the second room of the second fortress of world 7 in SMB3, and the main room of the second fortress of world 5 in SMB 3. I believe the footage speaks for itself here. No savestates used.
