Water is the primary fluid in Where's My Water? 2 and is the substance that is required to complete all of Swampy's levels. It is the first fluid introduced to the player, first appearing in the the Sewer.
- Water has a normal consistency in terms of movement. It behaves the same as Purple Water. Water is needed to complete Swampy levels and to collect Swampy Ducks, Swampy Mystery Ducks, Swampy Mega Ducks and Swampy Ducklings. If any amount of it enters Cranky's or Allie's pipe, the level is failed. Water will also kill Cranky Ducks.
