Koopa Chase

The Bowser Mobile is a vehicle owned by Bowser, which makes its first appearance in Super Mario 3D World. It is an initially purple muscle car with gold plating, spikes on the top, and wheel covers, with a Bowser hood ornament at the front. The car initially moves slow, but moves faster and faster when damaged, and when the player catches up with it. The car is also able to jump without the driver's input.

With the exception of World Bowser-Castle: The Great Tower of Bowser Land, the Bowser Mobile is Bowser's main weapon and mode of transportation in the game. It first appears in World 1-Castle: Bowser's Highway Showdown, where Bowser rides it for the duration of his boss fight. Bowser shoots Fireballs and tosses Kick Bombs from the car to attack the player, which could be kicked back to damage the car. After nine hits from a soccer ball bomb (three if they are knocked back with the cat form's scratch attack or rolled into) or twenty-seven hits from the boomerang suit's boomerangs, the Bowser Mobile destroys the highway and explodes, sending Bowser into the sky. The Warp Box to the Goal Pole then appears.

The Bowser Mobile makes a second appearance in World Castle-Castle: Bowser's Lava Lake Keep, where it gets a visual upgrade, with a mostly blue color scheme and neon wheels. The strategy is similar to before; however, a variety of terrain hazards have been added to the road, such as retractable spikes, jets of fire, and the occasional hole to the lava that lies underneath the road. After the same amount of hits as the previous, the Bowser Mobile is again wrecked, and the Warp Box to the Goal Pole is revealed. The Bowser Mobile (as it appeared in Bowser's Lava Lake Keep) makes its final appearance in the beginning of The Great Tower of Bowser Land, in its destroyed state. Players can hit it, but nothing happens other than the car making noise. The car mostly makes beep noises, but a soundclip of Bowser's laugh and some soundclips from Super Mario World can be heard after some hits.
