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 well known for its jumps.

Appearance in Mario Kart DS
This course reappears in Mario Kart DS as the third course in the Banana Cup. The layout of the course remains unchanged from the previous iteration. If a racer is tiny, they cannot complete the first jump necessary for completing this course.

Official descriptions

 * 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."
