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.

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of the course remains unchanged from the previous iteration, except with its enhanced 3D graphics and all the ramps has been replaced by small boosted ramps. 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. The course has never been available in Wi-Fi.

Official descriptions in Mario Kart DS

 * Instruction booklet: "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."
 * Mario Kart DS European website: "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."

Trivia

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