List of boss arenas in Mario Kart DS
The Mission Mode of Mario Kart DS uses several locations for its Boss Battles. It has a few arenas that only appear in Mission Mode, and since none of them are officially named, each of them have been given a conjectural name.
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.
When battling Big Bully and Chief Chilly there are two differences:
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 is based on the interior of the pyramid in Shifting Sand Land.
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. The background also has the Wood Blocks and falls from the Water Arena, except the waterfalls are now lavafalls. Unlike the first and most battles, the player will need to collect 50 coins while avoiding King Boo. Coins are scattered across the platform.
GCN Baby Park
This is where Goomboss is fought. It is completely identical to the race course version. However, in this version there are three laps instead of five, Goomboss throws Goombas on the track and Goomboss gets bigger when entering the next lap. Goomboss also throws Mushrooms sometimes, which bear a slight resemblance to Goombas from a distant viewpoint. Goomboss also cheats on the last lap and hops over the center of the divider.
GCN Mushroom Bridge
This is where Wiggler is fought. It is completely identical to the race course version, except that Wiggler often knocks out passing cars, slightly changing the course. The Item Boxes will all contain Stars. If the player bumps a car or truck with an Item Box inside, while powered-up with a star, they will earn a Dash Mushroom.
