The Bowser Express

The Bowser Express, or , is the fourth level in World Bowser in Super Mario 3D World and its Nintendo Switch port Super Mario 3D World + Bowser's Fury. This level is a train-style level that is modeled after Bowser. At the end of the level, the player must battle Pom Pom for the second time. This level features various enemies and obstacles, such as Spike Bars that swing back and forth.

In Mario Party 10, the Bowser Battle Minigame Bowser's Sinister Slots takes place on the Bowser Express.

The Bowser Express's background is reused in Super Mario Maker 2, in the airship theme of the Super Mario 3D World style.

Layout
The level starts on a platform near a train with some Skipsqueaks nearby. The player needs to hop on the train and avoid a nearby Spike Bar in order to reach an area infested with Conkdors and Bullies. A pool of water comes soon after that where the player must navigate past some Madpoles in order to get back on the train. The player must now avoid a Spike Bar and enter a room filled with Mini Goombas. A Hammer Bro guards the nearby pipe which brings the player to Pom Pom. After defeating her, a Warp Box brings the player to the area with the Goal Pole. As with the Bullet Bill Express, the train starts off at a platform before speeding up and leaving, and if the player chooses not to board the train or fails to in time, they will lose a life due to being left behind by the level's auto-scrolling camera and the train itself.
