GBA Bowser's Castle 2

Bowser Castle 2 is the fourth course of the Flower Cup in Mario Kart: Super Circuit. Its obstacles are falling Thwomps and thin rectangular gaps in the floor that make drivers fall into the lava below. The track is also notable for its jumping ramps; similar to those found in newer installments (after Mario Kart DS) which allows racers to perform Tricks. A large statue of Bowser can be seen in the background.

Mario Kart DS
This course returns in Mario Kart DS as the third course in the Banana Cup. The layout of the course remains unchanged from the previous iteration, except with its enhanced 3D graphics and all the ramps now encompass Dash Panels. If a racer is shrunk by a Lightning, they cannot complete the first jump necessary for completing this course and will fall to the lava. Missions 4-5 and 5-4 take place on this course. In 4-5, the player has to collect 15 coins without getting squished by a Thwomp, and in 5-4, the player has to drive through 10 numbered gates in order. The course has never been available in Wi-Fi.

Mario Kart Tour
MKT Icon BowsersCastle2GBA.png The course reappears once more in Mario Kart Tour, stylized as Bowser's Castle 2. It was added into the game at the start of the Hammer Bro Tour alongside SNES Donut Plains 1, which was also last remade in Mario Kart DS. Though the standard layout is largely the same, there are now Barrel Bombs that are in certain areas, and some of the lava pits are smaller or absent. The platform directly after the first jump has a slightly different layout. It now uses the background of GBA Bowser's Castle 1. It is favored by the Ice Bro, the Fire Bro, and Dry Bowser.

Hammer Bro Tour
The course made its debut in the Hammer Bro Tour, alongside SNES Donut Plains 1. It appears as the first course in the Bowser Cup and the location of the challenges in the Yoshi Cup, the Luigi Cup, and the Ice Mario Cup. It also has a Reverse variant which appears as the third course in the King Boo Cup, and a Trick variant which appears as the second course in the Birdo Cup.



Mario Kart DS

 * Instruction booklet bio: "This course appeared in Mario Kart: Super Circuit™ for the Game Boy Advance™. It's a flat course, but the lava trenches all over make it really dangerous."
 * European website bio: "Tight right-angled turns abound on Bowser's turf, as you contend with angry Thwomps threatening to squash your kart into a pancake, make daring boost-assisted leaps over lava pits, and cut corners mere millimetres away from flames hotter than Bowser's breath."

Mario Kart Tour

 * Mario Kart Tour Twitter: "Stay on course or you'll take a dip in the lava in Bowser's Castle 2. You'll want to keep an eye out! The path to victory is lined with Thwomps and Barrel Bombs. Keep your wits sharp as you take on Bowser's most fiendish course yet!"

Trivia

 * In Mario Kart DS, one can make a high jump by hopping at precise timing when driving over one of the boosted ramps.
