Dirt is one of the many things that you want to use to guide the water to Swampy's shower. Unlike some of the other things you use your finger to cut through it. Dirt can not affect the water in any which way. They're in nearly all of the levels in Where's My Water exept level 4-14, level 7-13, level 4-16, level 7-3 and level C1-11.
- The achievement Efficient Cut is when you cut/dig with 2 fingers at the same time.
