Sour Root Cave (PMU 6)

Sour Root Cave, as in PMU 6, was the first dungeon to provide a HM for the player to have and the hardest dungeon that is completely non-random. It contained HM Cut, which allows the player to cut down small trees, giving access to hidden areas across the regions. It was filled with all sorts of Grass- and Bug-type Pokémon.

Scenery
The scenery in this dungeon is the same for all floors: Dirt, grassy cliffs and growing roots.

Pokémon
The Pokémon here are mainly Grass- and Poison-types.
 * Budew
 * Bellsprout
 * Nincada (Dawn/Dusk)
 * Caterpie
 * Metapod
 * Oddish
 * Kricketot
 * Weepinbell (Boss)
 * Ivysaur (Boss)

Items
The items that are in this dungeon are basic for explorers, however this dungeon introduces status conditions, mainly Poison, so there are Pecha Berries in this dungeon. The bosses here also drop items, this dungeon also exclusively offers HM Cut, something that is needed to make the game a lot easier.
 * Oran Berry
 * Pecha Berry
 * Leppa Berry
 * Apple
 * Leaf Stone (Weepinbell)
 * HM Cut (Weepinbell)
 * TM Payback (Weepinbell)
 * Tiny Mushroom (Ivysaur)
 * Poké (Ivysaur)

Dungeon Objective
The dungeon, like all others, requires you to climb the dungeon floors and beat the boss for completion. However, when you get far enough into the dungeon, you will reach a plant blocking the way, and you have to go up to face the Weepinbell to get cut.

After you gain the HM Cut and teach it to a Pokémon, you go left and face off with the Ivysaur.
