GBA Bowser Castle 4 is the fourth and final course out of the four Bowser Castles in Mario Kart: Super Circuit. It is the third course in the Star Cup. It includes dangerous jumps over death-defying lava, Thwomps that will squash the drivers, and Mechakoopas that are spread around the end of the course! This is probably known to be the hardest Bowser Castle in the game.
