Editing Bowser Castle (Mario Kart DS)

The players start by passing through a metallic doorway with a statue of Bowser's face above (which plays his laugh on entry). They then pass through a hallway with [[Thwomp]]s. After climbing two sets of stairs they cross a thin bridge, which has barriers so racers cannot fall back down to the hallway below. Next, they enter another circular room, which has a large metal circle as part of the floor that spins counterclockwise, while the racers are going clockwise. [[Burner]]s from Airship Fortress appear in this room. A hallway with a Thwomp follows. This Thwomp actually moves horizontally out the window, then comes back into the castle. After a right turn and then a left turn, there is a spiral path. If racers are not careful, they can fall a long way down into lava or back to the beginning of the spiral.

Racers will then encounter two paths; crossing a rotating cylindrical bridge, or driving down to a garden below it. The bridge provides a much faster route to go through, and if they fall off, racers can simply land in the garden, but will lose some time. The garden is partially paved and have grass parts that slows them down. Afterwards, racers will drive through metal grates with a large [[Dash Panel]] ramp that launches them to the final stretch that consists of four moving platforms, allowing racers to take a right turn to the finish line. The platforms move from left to right, but are not difficult to traverse due to their moderate speed. Heavy racers can push lighter racers off during the ending section; however, some of the path has barriers preventing them from falling. The path from the platforms to the finish line is comprised of the same metal grates from earlier.
