World 6-2 is the second main level of World 6 in New Super Mario Bros.. It is unlocked after completing World 6-1 or World 6-A, and completing this level will unlock World 6-Fortress. This is the last level in the game to feature The Beach Overworld Theme.
The level starts off on sand. The player will have to make a few jumps over several Spinies to reach a red Warp Pipe. A flying Question Block is also in this beginning section. After entering the pipe, Mario reaches a section with constantly changing water levels. By the first palm tree, Mario will find a Question Block with a coin in it. Located above are two invisible blocks, with one of them having a vine. Climbing the vine leads to a block that has a P Switch that must be used to obtain the first Star Coin to the right. After this section, Mario can find two warp pipes, both being cannons. One of them takes the player into a bonus area in the sky that has many blocks, most containing coins but also some have 1-Up Mushrooms. The other pipe takes the player forward through the level, leading to the second Star Coin. The exit of the yellow pipe from the bonus area and swimming through the rising water in the main level both lead to the checkpoint. After some platforms, the player can find a Question Block containing a Starman, which can be used to dash through Spinies to obtain the third Star Coin. Moving forward is an uphill with more Spinies leading to a yellow Warp Pipe that takes Mario to end of the flagpole, past the last of purple platforms.
- Star Coin 1: After entering the opening red Warp Pipe, two invisible blocks are located above the first palm tree. One of these has a vine. Climbing the vine leads to a Brick Block that has a P Switch. After hitting the switch, Mario must carefully jump across flying blocks and stationary Brick Blocks that result from coins to get the Star Coin.
- Star Coin 2: After traversing across three green Warp Pipes, the player must use the water and wait for it to rise to jump up to the Star Coin.
- Star Coin 3: Not too long after the checkpoint, there is a Question Block containing a Starman. Mario must grab the star and dash through Spinies underneath while the water is low to reach the Star Coin.
