SNES Bowser Castle 3

Bowser Castle 3 is the fourth track of the Star Cup in Super Mario Kart. It was subsequently reused in Mario Kart: Super Circuit as the second track in the Extra Star Cup. Like every Bowser Castle course, the entire race is held inside a large castle room filled with a big lava pool.

Description
Typical elements of Bowser Castles, including falling Thwomps, zippers, jump lines and forks, are all to be found here. One major fork allows the player to choose one of three ways. The leftmost has six coins and one zipper, but is farthest away and narrows the following turn into a hairpin. The easiest path to reach is the right one, which has a jump line and a zipper directly behind such that a player who hits the jump line passes over the zipper. To reach the zipper, the player must time a hop over the jump line and activate the zipper. The middle path has six coins and two jump lines with Item Boxes positioned behind them.

Mario Kart: Super Circuit
Bowser Castle 3 reappeared in Mario Kart: Super Circuit, and is the second track in the Extra Star Cup. It uses the background from that game's own Bowser Castle 1. The Thwomps and zippers were removed from the track, along with the jump pad in the rightmost path at the end. Also, the ? Panels in the first split path were reduced to just three Item Boxes (one on both sides early on, and one in the middle afterwards).
