'''Bowser's Highway Showdown''', also known as '''{{world|1|castle3dw}}''', is the final standard course of [[World 1 (Super Mario 3D World)|World 1]] in ''[[Super Mario 3D World]]'' and its [[Nintendo Switch]] port ''[[Super Mario 3D World + Bowser's Fury]]''. It is a castle with many [[Kick Bomb]]s, with [[Bowser]] serving as the boss. The green Sprixie Princess is held prisoner in the castle. It is unlocked by completing [[Plessie's Plunging Falls]] or [[Switch Scramble Circus]]. Ten [[Green Star]]s are needed to enter and its own completion frees the green Sprixie Princess who builds a [[Clear Pipe]] to [[World 2 (Super Mario 3D World)|World 2]].

==Layout==
This course begins in a road with two [[Kick Bomb]]s, a [[Green Ring]], and a [[Goomba Tower]]. If the player, in cat form, climbs on top of the wall behind these things and waits, they will see an 8-bit [[Super Mario (form)|Super Luigi]] swimming; this is the level's hidden 8-bit [[Luigi]]. Later on, there is an area with two [[Cannon]]s shooting Kick Bombs. Some [[Thwomp]]s 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 Block]]s. 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 [[Bowser's Muscle Car]]. 

Players defeat Bowser by launching the Kick Bombs he throws by running into them. The player will score full damage if they hit Bowser directly, but the car will take three hits before actual damage is scored. After a while, Bowser will begin to spit fire onto the road which will leave hazardous flaming residue where it lands. Once Bowser is defeated, a Warp Box appears and leads the player to the [[Goal Pole]] and the green Sprixie Princess.
