GBA Bowser's Castle 4

Bowser Castle 4 is a race track in the game Mario Kart: Super Circuit in the unlockable Special Cup. It is the 3rd race in the Special Cup. This course features many dangerous jumps over lava pits, several Thwomps blocking the way, along with Mechakoopas at the end of the race. It is the only GBA Bowser Castle course that has yet to become a retro course in a later Mario Kart game. However, it is a definite candidate for the 8th Mario Kart game.
