Deepwater Dungeon
Template:Levelbox
Deepwater Dungeon, otherwise named World 
Bowser-5 is the fifth level in World Bowser from Super Mario 3D World, becoming accessible along with Footlight Lane after the completion of The Bowser Express. This level takes place in a dungeon with moving bodies of water, spiked walls, and a short Plessie section. Its completion unlocks A Beam in the Dark.
Layout
The level starts off with the player falling down before sliding down to a pit of water that rises/drains every few seconds that has Madpoles. After that, the player will have to swim on a series of moving bodies of water before reaching the checkpoint. On the second body of water, the player must avoid blue spiked walls. This level's stamp can be found in this area.
The next area includes players riding on Plessie before a Donut Block bridge and a body of water with red moving spiked walls. Then the player traverses a series of moving bodies of water while avoiding moving spike walls. After that, the player must go through a Warp Pipe to head to the Goal Pole.
Green Stars
- Green Star 1: Before the checkpoint, the player will need a Cat Suit to climb to an invisible wall after the moving bodies of water.
- Green Star 2: After the Plessie section, the player will again need a Cat Suit to climb walls to reach the star.
- Green Star 3: Before the Warp Pipe to the Goal Pole, the player will again need a Cat Suit to find a Cloud Cannon where the player will find the star in Coin Heaven.
Stamp
In the first set of moving bodies of water where the player must avoid blue spiked walls, the player should go up the top left path where the stamp is in an alcove.
