Layout
This course begins in a road with two Kick Bombs, a Green Ring, and a Goomba Tower. Later on, there is an area with two Cannons shooting Kick Bombs. Some Thwomps and a Cat Wheel appear soon after. A short path with a Goomba Tower and a Green Star follows. The road ends in a wall made of many stone Brick Blocks. The player must use some nearby Kick Bombs to break the wall, and get to the nearby Warp Box leading to the boss. After climbing up a staircase, the player encounters Bowser in his car.

The strategy to defeating Bowser is quite simple: The player must knock back the Kick Bombs he throws. The player will score full damage if they hit Bowser directly, but the car will take 3 hits before actual damage is scored. After a while, Bowser will begin to spit fire onto the road which will leave flaming residue where it lands? The player must steer clear of these fiery puddles. Once defeated, a Warp Box will appear which leads the player to the Goal Pole and the Green Sprixie Princess.
