List of boss arenas in Mario Kart DS

The Mission Mode of Mario Kart DS uses several locations for its Boss Battles, some of which were created for the Mission Mode and are not found anywhere else. Please note that the arenas exclusive to Mario Kart DS are not named, and thus, the name used for them here are conjectural.

Water Arena
The Water Arena is where both Big Bully and Chief Chilly are fought. The Arena consists of a Platform surrounded by Water. There are no boundaries, allowing both the player and the boss to be knocked in the water.

The Background of this stage bears some resemblances to the interior of a Fortress in Super Mario Bros. 3. A few waterfalls and empty ? Block are also present.

When versing Big Bully and Chief Chilly there are 2 differences. 1. There are 3 ? Blocks compared to 1. 2. When versing Chief Chilly, the Arena is slightly bigger.

Sand Arena
The Sand Arena is where both Eyerok and Big Bob-Omb are fought. Much like the Water Arena, it is completely featureless. However, unlike the Water Arena, there are boundaries, meaning that the player and the Boss can't be knocked off-stage.

The background of this stage seems to be based on the interior of the Pyramid in Shifting Sand Land.

Lava Arena
The Lava Arena is where King Boo is fought. The arena consists of a Platform above a pit of Lava. The platform is a lot bigger than the Water and Sand arenas, but it has quite a few holes in it, which may result in falling into lava.

This is where Goomboss is fought. It is completely identical to the race course version. But this time, there are Goombas on the track and Goomboss gets bigger when you enter the next lap. The Goomba King throws mushrooms which bear a slight resemblance to Goombas from a distant viewpoint.

Mushroom Bridge

This is where Wiggler is fought. It is completely identical to the race course version, except that Wiggler will often knock out passing cars, slightly changing the course. The ? Blocks will have Stars in them. If you bump a car or truck while star, you will earn a Dash Mushroom.
