Soggy Sewers is a section of the second world in Newer Super Mario Bros. Wii, with the rest of World 2 being in Rubble Ruins. It contains levels 2-2 through 2-Towernsmbw.png. It's a brown underground sewer-themed area located below the desert.

Its tower boss is King Thwomp.


Soggy Sewers is a brown, mushy, pipe-laden area with multiple lakes, which takes place under the upper part of Rubble Ruins. There are Piranha Plants, Jump Blocks, Munchers, and colossal stalagmites that scatter the area.

Soggy Sewers can be accessed through completing Cactus Cove of Rubble Ruins or through completing Leafpile Fortress of Goldwood Forest. Completion of Pipeline Tower grants access to Barrelband Wilds of Rubble Ruins.

  • Soggy Sewers is the only major world that has a Tower but no Castle or Airship. (Rubble Ruins has the opposite trait.)
