Sour Root Cave, otherwise called Sour Root or SRC, is the lowest-level dungeon to provide an HM to players. It's found in Exbel, just north of Grassroot Town. It contains HM Cut, which allows the player to cut down small trees, giving access to various areas across the map.

The dungeon is home to Grass, Bug, and Poison Pokémon. This dungeon introduces status problems, the most notable of which is poison. You can also obtain HM Cut at the midpoint.

The Pokémon in this dungeon are mainly in the level range of 3-10.

The dungeon was introduced in PMU 6.

    "Top of Sour Root" Glitch in PMU 6.

  • There was a glitch in PMU 6 where players could walk on top of the overworld entrance to Sour Root. This was eventually fixed.
  • There was a glitch where you could rebattle the mini-boss without exiting the dungeon, which made it easier to farm HM Cut. They eventually removed that problem due to abuse.
  • Weepinbell is Level 14, while Vileplume is Level 17.
