World 5-4 is the fourth level of World 5 in New Super Mario Bros. Wii. In this level, Mario must travel on a plank to the pole to avoid the poison. This level also does not have a midway point.
The level starts in a area with Goombas falling from above, and four Invisible Blocks, one containing a Super Mushroom. The player must enter a Warp Pipe, which leads to a Limited Lift that is used to cross poison. A ? Block containing an Ice Flower is to the left of the exit pipe. Enemies including Goombas, Mini Goombas, Koopa Troopas, Bob-ombs, Piranha Plants, and Big Piranha Plants land on the Limited Lift, causing the numbers on the Limited Lift to increase from 0 up to 5, which causes it to turn red and stop moving. To make the Limited Lift start moving again, the player has to defeat enemies so that there are less than five. Later, a POW Block can be found and used to defeat the enemies on the Limited Lift. At the end of the area, a Warp Pipe leads the player to the area containing the pole.
- Star Coin 1: The first Star Coin is floating high over the Limited Lift, just below the area before the first one with Mini Goombas. Mario and co. should jump up to the Star Coin from an enemy.
- Star Coin 2: Mario and co. should pick up the POW Block and activate it once the Limited Lift passes the enemy platform in which the POW Block rests. This makes the second Star Coin fall onto the raft.
- Star Coin 3: The third Star Coin is at the end of the level, blocked off by several blocks. Mario and co. should break some of the blocks with a Bob-omb, wait for the Limited Lift to float under the Star Coin, then fall to it.
