DS Luigi's Mansion

Luigi's Mansion is the last race course of the Mushroom Cup in the game Mario Kart DS. Outside the mansion is Boo Woods which has a graveyard surrounding the mansion and beyond it, a swamp of mud with moving trees. When a character runs into one of these trees, instead of spinning out or rolling over, the character instead will just get stuck on the tree as if it were a wall.

Racers start outside the mansion in a section of Boo Woods, and they will go through a curl path to the entrance of the mansion, running along a narrow hall that leads the racers downwards to a room beneath the lobby. The racers then go out of the mansion, crossing a stone path tunnel, where they reach the graveyard, leaving the mansion. Finally, racers end up crossing the swamp to cross the checkered line.

Missions
Missions 1-6 and 2-4 take place on this course, with Luigi driving in both of them.

In mission 1-6, the player has to exit the mansion in reverse, and in mission 2-4 the player must destroy 5 item boxes.

Staff ghost
The staff ghost in this track is 1:59:357 using Luigi in the Streamliner.

Mario Kart 7
Luigi's Mansion appears as a Retro course in Mario Kart 7 as the final track in the Shell Cup. The only changes are the ramp that lets racers use gliders, and the Boo and the portraits are replaced by solo arts of Boo who will attempt to pop out when the racer passes. The mansion's foyer has been redesigned to more closely resemble its original appearance, instead of the relatively simple single-story room seen in Mario Kart DS. Also, there seems to be a ramp towards the end of this course, where there is mud and part of the gate wall leading to Boo Woods is broken as a small path to cross through. There are two gliding segments: one on the aforementioned ramp, and the other on the right when in the mud segment.

Official descriptions

 * European website: "After rescuing Mario from the dark dungeons of this dreary old place, Luigi has decided to make some money from his mansion by turning it into a racetrack. Perpetual darkness means you'll need your headlights on for this one, especially since the trees have a tendency to walk around..."

Trivia

 * The Boos that pop out of the portraits in Mario Kart 7 were originally going to appear in Mario Kart DS.
 * Luigi's Mansion in the only Luigi-themed race course in the series that isn't a "Circuit" type course.
