Bowser's Castle is the final track in the Star Cup of Mario Kart 64. The course features many 90 degree turns and a variety of hazards such as Thwomps, fire-breathing statues, and lava bridges. In a giant hallway of the castle, a pair of Thwomps moves along in front of the driver, following their motions, and will either block them are fatally squish them. In one area of the castle, a green Thwomp, nicknamed Marty by fans, can be seen behind jail bars laughing at passing racers. This track returns in Mario Kart Wii in the Lightning Cup with a few minor differences. The fire-breathing statue will cause players to spin out, and lava geysers near the end were added. There are also rattling Thwomps. The mysterious green Thwomp, Marty, is now a regular Thwomp's color, but he still laughs.
- This is the only Bowser's Castle track in the Mario Kart series to be in the Star Cup, rather than the Special Cup (excluding the Bowser Castle tracks from Super Mario Kart and Mario Kart: Super Circuit).
- This is also the only non-GBA Bowser's Castle track in the series that was remade as a retro course, not counting Mario Kart: Super Circuit's Super Mario Kart remakes.
