Bowser's Castle (Mario Kart: Double Dash!!)

Bowser's Castle is a race course in Mario Kart: Double Dash!!. Racers start out outside of the castle and enter through a large doorway shaped like Bowser. As they precede through the hallway, Thwomps will try to spin them out or squish them. Racers will then travel over a pit of lava and through a circular room filled with Podoboos. During the final stretch of the course a statue of Bowser will shoot fireballs at oncoming cars. If the players have any trouble, Bowser's famed laugh will emit. Escaping the castle by a jump only leads to the front of the track again for the second lap.

Course layout
The race starts in a quite straight dirt road that leads into the castle, past a drawbridge and into an opening that is shaped like Bowser. The players can then see that the path splits, but it results in two identical paths that also have the same obstacles: Thwomps. Past that, where the path meets again, is a 90 degree turn to the left with leads into another straight path with Thwomps. In split screen mode, the Thwomps in this lane are absent. After the Thwomps, there is another turn left that leads into a room with lava on the ground.

In the room with the lava on the floor, the players drive over a chain link bridge with a square in between. In single player, Podoboos will fly out of the lava and try to burn the players. Falling off the chain link bridge results in falling in the lava. After the chain link bridge is a ramp with boost panels in it. Past the ramp is a long curve that spirals upwards into a nearly complete circle. Succeeding the curve is another circular room, this time with fire balls that orbit a pillar in the center. The players can see portraits of Bowser Jr. on the walls of this room.

Past the circular room is a short path that turns to the left in a 90 degree angle, which also leads to another 90 degree angle turn. It leads outside and the players can see the start of course on this road. However, if players attempt a shortcut here, the game will consider it as falling off the track and place the racer back on the track. The road has two somewhat steep ramps that aren't exactly straight, but they don't slow down the players. Past the ramps is a U-turn that leads to a straight road. The road then curves to the left, then makes a U-turn that leads into another interior.

In this room, there is a giant Bowser Machine that shoots one fireball at a time to the players. Despite that, the road is straight. After that is a turn left and a curve right that leads nearer to the Bowser Machine. The players then makes a left turn that also has the Bowser Machine's fireballs, but it isn't getting directly shot at the players. The road is straight and there is a ramp that has boost panels in it. After the ramp is a curve left and the finish line.

There is one notable shortcut in this course that does not require the use of a Mushroom. It is in the room with the Bowser machine. Before the curve that leads the players right, one can notice an opening in a wall, directly where the Bowser Machine belches out fire from. The players can drive over that, but must steer quickly or risk falling into the lava just after making the ramp. The players also have a risk of getting burnt by a fireball just before the jump, making the players also fall into the lava.

Trivia

 * The background of the course looks very similar to that of the Mario Kart: Super Circuit course Broken Pier.
