Bowser's Factory

Bowser's Factory is a race course in Mario Kart Arcade GP DX, appearing in the first and third rounds of the Bowser Cup (which is only available for 100cc and up), while its counterpart, Bowser's Castle, appears in the second and fourth rounds of the same cup. The course uses a revamped layout of the Bowser's Castle of Mario Kart Arcade GP and Mario Kart Arcade GP 2, but is a lot more mechanical in comparison.

Racers start by driving into the castle (with a very large statue of Bowser looming over the gateway), and making a hairpin turn in a room full of moving gears and pistons above lava. Afterwards, they drive straight ahead to the entrance of the eponymous factory section, which about half of the course takes place in. Upon entering the factory, the racers turn right and move along the path as various Bob-ombs are being produced, overseen by King Bob-omb. After that, racers drive through a hallway under a giant Thwomp, held in place with two platforms that prevent it from collapsing, to then turn right as they enter a section in which Banzai Bills are being placed in hatches. They then exit the factory, ending up on a cliff in a volcanic area, which path leads them back to the entrance of the castle.
