World 3-3 (New Super Mario Bros.)

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

Layout
This level is difficult without a Fire Flower because of all the Cheep-Cheeps and Bloopers. Mario must go into the Warp Pipe, which takes him underwater. Mario needs to keep swimming, while avoiding all of the Cheep-Cheeps and Bloopers. Almost halfway into the level, go down to find the first Star Coin. The player will also find a ? Switch. Pressing it will temporarily stop the strong bubble currents. Go right, then down (past the Yellow Pipe), then continue right. The player will see a set of ascending pipes. The player should go to the third pipe they see to enter a room filled with Bloopers. This room contains the second Star Coin. Continue through the main part of the stage to find the Exit Pipe. Instead of going through it, go down to find the third Star Coin. As soon as the player grabs it, swim up to the Exit Pipe rapidly to avoid the Bloopers that appear out of nowhere. Past the Exit Pipe is the Flagpole.

Star Coins

 * Star Coin 1 - Before hitting the orange switch to stop the bubbles, look to the left to see the first Star Coin guarded by a roaming Blooper.
 * Star Coin 2 - After passing the Red Ring, head into the third pipe from the left. Avoid the Bloopers and Blooper Nannies and go to the lower right corner. Grab the Star Coin and head to the upper right corner to leave.
 * Star Coin 3 - Before leaving through the Warp Pipe to the flagpole, head to the bottom of the level. Get the Star Coin and quickly head back to the surface as four Bloopers will appear.

Enemies
