Sour Root Passage is a small room containing various warp panels after the player proceeds from the 5th floor of Sour Root Cave. To access the stairs which will lead to the mini-boss Weepinbell, the player must solve a warp puzzle. Players whom wish to recruit Oddish can find them here at night.

The solution for the warp panel is as shown below.

After completing the warp puzzle at the Sour Root Passage, the player will arrive at Sour Root Chambers, the midpoint of Sour Root Cave. A timid Weepinbell will be caught by surprise when the player arrives, and proceeds to attack the player after some hesitation. Upon defeat, Weepinbell will drop HM Cut.

    Original PMU 6 Entrance to Sour Root

  • This dungeon was initially introduced in PMU 6, and is reintroduced as one of the original dungeons in PMU 7.

    "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 player 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.
