Mineral Cavern, also known as MC, is a dungeon found south-west of Grassroot Town in Exbel. It provides the player HM Surf at the end of the dungeon, and has no boss to defeat in order to complete the dungeon. 

After completing Mineral Cavern, the players gain access to Southern Sea and Crescent Islet.

The Pokémon in this dungeon are mainly in the level range of 24-30 and are mostly Water-Types.


It may occasionally rain in this dungeon, but due to Psyduck's Cloud Nine ability, the weather in Mineral Cavern is often clear.


Mineral Cavern features compact, beige floor tiles occasionally littered with rocks with light, concrete-grey walls. Large quantities of water are found every floor, and scattered puddles are common. There is darkness in the dungeon starting from the first floor all the way to the last floor.

On B4F, a set piece boasting 4 siltstones in a large square room can be seen in Mineral Cavern.

Mineral Cave Opening

Mineral Cave Opening

You arrive here at the end of the dungeon, where a single HM Surf is found.

From here you may go up the ladder back to the entrance of the dungeon, or go down to Exbel Peninsula. If you didn't bring a Pokémon who can learn Surf or a Pokémon who already learned Surf, you'll have to go through the dungeon once more.

Outside of the opening, you can choose two routes. Going north into the cave will take you back to the opening, while going south will take you to a small port leading to South Outpost Island if you have Surf. If you use Surf or press enter while your Surf Pokémon is active, it should say, "Water currents lead into the distance... would you like to use Surf?"


Pokémon in bold are recruitable. Please visit the Recruitable Pokémon page for more information.

Dungeon Objective

The main objective of this dungeon is to obtain HM Surf, and gain access to the dungeons Southern Sea and Crescent Islet.

This dungeon is also the first dungeon accessible for players to recruit Psyduck, Marill, Azumarill, Shuckle, Corphish, and West Sea Form Shellos.


  • Players can continue onward to Southern Sea by exiting via the pathway southwards from Mineral Cave Opening after completing the dungeon, or alternatively warp back to the Crossroads by taking the ladder north.
  • If the player plans on going to the Southern Sea but do not have a Pokémon that can learn Surf, have a space open in your party and recruit a Water-Type Pokémon in the dungeon before exiting the dungeon.


  • This dungeon was made by the former Mapper, Dandy.
