World 5-4 (New Super Mario Bros. Wii)

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 flagpole to avoid the poison.

Layout
The level starts in a area with Goombas falling from above, and four Hidden Blocks, one containing a Super Mushroom. The player must enter a Warp Pipe, which leads to a wooden plank that Mario must use to avoid the poison and reach the flagpole. A ? Block containing an Ice Flower is to the left of the exit Pipe. Enemies including Piranha Plants, Goombas, Koopa Troopas, Bob-ombs and even coins land on the plank, causing the numbers on the plank to increase from 0 up to 5, which causes it to turn red and stop moving. To make the plank 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 plank.

Star Coins

 * Star Coin 1 (pictured): The first Star Coin is floating high over the raft, 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 raft 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 raft to float under the Star Coin, then fall to it.
