World 4-4 (New Super Mario Bros.)

World 4-4 is the fifth level of World 4. Alternatively, World 4-A can be used to bypass this level.

Layout
This level features a lot of Wigglers. Mario can complete the Red Ring by getting a boost from a Wiggler. The first Star Coin is found in a small cave near a Wiggler. Later, Mario needs to hit a block that contains a Beanstalk to climb up it and continue. If the player goes left and Wall Jumps off the wall, they will find the second Star Coin. The last Star Coin can be obtained by sliding on a wall next to it, then Wall Jumping to the small pipes. After going through the Yellow Pipe, Mario reaches the flagpole.

There is a secret area in this level, reached by using a Mini Mushroom to go down the second small Warp Pipe from the left where there are four together, with a Wiggler on top. This secret area has a Mega Mushroom, and a lot of pipes to smash, along with some coins to collect.

Star Coins

 * Star Coin 1 - Mario should throw a Koopa Troopa shell against the left wall so it bounces off the wall and takes out the Wiggler along with itself. Then, Mario must slide down the right wall to land in the area with the Star Coin. Alternatively, there is a Hidden Block containing a Beanstalk, just to the right of the other blocks below the Star Coin.
 * Star Coin 2 - After reaching the area with a Random Block, Mario should climb the Beanstalk and head to the left. Next to the Brick Block is a hidden Beanstalk that Mario must climb to reach the second Star Coin.
 * Star Coin 3 - Mario should carefully slide down the wall of a cliff, and then Wall Jump to some nearby mini pipes.
