Switching Sewer (or World 2-3) is the third level of Crystal Sewers from Newer Super Mario Bros. DS. It takes place in an actual sewer filled with Piranha Plants and Manholes.

Star Coins

  • Star Coin 1: At the start, when you hit the ! Switch, quickly get up the Red Blocks. At the top of these Red Blocks will be the Star Coin, too high to reach without the blocks.
  • Star Coin 2: Right after the first Star Coin, this'll be in plain sight, blocked off by some Stone Blocks. Get past the Big Piranha Plant, then activate the ? Switch up above. Then, instead of entering the Warp Pipe, jump up to make the Flipper close, and grab the second Star Coin.
  • Star Coin 3: You need to be Super Mario or up to get this Star Coin. After the checkpoint, there'll be a ! Switch. Hit it, then break the Brick Blocks near it. You'll then have to wall jump up to get the Star Coin.

Secret Exit

This level features a secret exit, which'll lead you to Hydroskip Drain. After the checkpoint, there'll be a ! Switch. Once you activate it, run right as fast as you can. Avoid the Flippers below, then enter the Warp Pipe which is only accessible with the Red Blocks. This'll lead you straight to the secret exit.
