World 4-3 is the third level of World 4 of New Super Mario Bros. Wii.

Layout
The level begins next to a Huckit Crab. Two ? Blocks and another Huckit Crab follow. Three lifts float above water, where a Big Urchin and some Urchins are found. A Huckit Crab is found on the second lift, and a ? Block containing either a Super Mushroom or a Penguin Suit is above the third lift. A Huckit Crab is found under a platform consisting of a ? Block and two Brick Blocks with a Koopa Troopa on top. A Super Star is found in the second Brick Block. The player then arrives at another lift, where Urchins and a Huckit Crab are found. A P Switch is also found, followed by an area with multiple Urchins and Huckit Crabs, one of which is above a Brick Block containing a Mini Mushroom. A Big Urchin is found before the Checkpoint Flag.

After the Checkpoint Flag, a ? Block and a group of Huckit Crabs are found on rocky platforms. More Huckit Crabs are found after some water, followed by an area with a log platform and multiple platforms made of Donut Blocks. Big Urchins and Urchins are in the water, while Koopa Troopas are on the Donut Blocks. A Red Ring is also located above Donut Blocks. A Warp Pipe is found at the end of the area, which leads to an area with coins that can be reached using Mini Mario and the Goal Pole.

Star Coins

 * Star Coin 1: The first Star Coin is near the beginning of the level, floating above a ? Block. Mario and co. should get on the ? Block and jump from it to the Star Coin.
 * Star Coin 2 (pictured): Shortly after the first Star Coin, there will be a row of two Brick Blocks and a ? Block with a Red Koopa Troopa on top. The middle Brick Block contains a Super Star. Mario and co. must obtain the Super Star then hurry along and kill the Big Urchin to make the second Star Coin accessible before the Super Star's effects wear off.
 * Star Coin 3: A Mini Mushroom is required for this one. To the direct right of the stairs-like platform with two Huckit Crabs is a small Green Pipe guarded by another Huckit Crab and an Urchin. Mario and co. must get past these enemies and enter the Pipe. This Pipe leads to an underwater area with two Big Urchins and the third Star Coin, which is surrounded by several other Coins in the shape of a heart.
