Pokémon world locations

The Grand Underground (Japanese: 地下大洞窟 Grand Underground Cave) is an area in Pokémon Brilliant Diamond and Shining Pearl found beneath the entire Sinnoh region. Players can travel to the Grand Underground using an Explorer Kit, given to the player by Underground Man in Eterna City.

It takes the place of the Underground from Pokémon Diamond, Pearl, and Platinum.

Changes from Diamond and Pearl

Lucas and Dawn in the Grand Underground
Digging
  • The map now conforms to the shape of the Sinnoh landmass instead of a large square layout. Notably, it excludes Iron Island, Fullmoon Island, and Route 223 onwards, however the Explorer Kit is usable on Fullmoon island but not the other locations.
  • The map is still split into six disjoint areas like the original Underground, but the sizes and locations of the six areas do not match those of the original Underground.
  • Areas now include Pokémon Hideaways, and each area now corresponds to a different aesthetic environment.
    • At least three areas include surfable water. These hideaways are the Swampy Cave, Lakeside Cave and the Glacial Cavern.
  • The digging minigame returns following closely to its original incarnation with the exception of digging up Pokémon statues, which come from Stone Boxes.
    • If the player runs out of digging spots, more will appear once the player enters and exits a Hideaway.
    • After the Sinnoh Pokedex is completed, Mysterious Shard S and Mysterious Shard L will start appearing in the underground.
  • Secret Bases return and are created using a Digger Drill as before.
    • Bases can only be decorated with statues and pedestals to place them on.
    • The flag stealing mechanic has been removed.
  • Goods and Traps, with the sole exception of the Digger Drill, have been removed.
  • Spheres no longer have a numerical size and are instead categorized as Small or Large. They can no longer be buried either.
  • Instead of goods or traps, merchants (who appear as Hikers) in the Grand Underground can exchange treasures and for spheres. Spheres can now be exchanged for pedestals, items, and TMs.
  • The radar is now triggered by pressing [R] and searches the area around the player's location.
  • The Grand Underground supports online communications, compared to the original games which only supported local communications.
  • Diglett and Dugtrio will occasionally pop out and leave pink sparkles that give 1 and 3 points respectively. Accumulating 40 of these points causes "something good to happen" which increases the shiny odds for Pokémon in Hideaways to 1/2048 for a period of 4 minutes. Additionally, all Stone Boxes found while digging during the 4 minute bonus period will be Gorgeous Stone Boxes. A whistle is heard when this period begins and once more when it ends. The bonus and progress gauge is shared between all players connected to the same instance of the Grand Underground. If all connected players leave the Grand Underground, this gauge resets to zero.
  • Steps taken in the Grand Underground count towards Egg distance as well as the step counter app.
  • Some Hikers found in the Grand Underground allow the player to rest, acting as a Pokémon Center.

Zones

The Grand Underground is organized into six zones, with each zone containing Pokémon Hideaways.

Pokémon Hideaways

Pokémon Hideaway

Pokémon Hideaways (Japanese: ポケモンの Pokémon Hideaway) are new places where wild Pokémon can be encountered. Unlike the main overworld, these areas feature symbol encounters. Each of the seven areas contain at least one large Hideaway, though multiple, smaller Hideaways are scattered throughout the map. Various hideaways - particularly larger areas - include items for Trainers to discover, such as Deep Sea Scale. Some Pokémon available in the game can only be found in Hideaways.

The variety of Pokémon encountered increases at five milestones - obtaining TM97 Defog, obtaining TM96 Strength, earning the Icicle Badge, obtaining TM99 Waterfall, and unlocking the National Pokédex - while each badge earned will increase the strength of the Pokémon. The player does not need to be able to use the TM outside battle in order for more variable Pokémon to appear. All Pokémon in the Hideaways will have at least one Egg Move if applicable, and The Grand Underground also unlocks some Egg Moves that would otherwise be unobtainable, e.g. Aura Sphere for Squirtle.

Hideaway locations include:

The level of Pokémon available in the Grand Underground varies, depending on the number of Gym Badges the Player received and their progression in the game.

Progression Level Ranges
1 Badge 16-20
2 Badges 25-29
3 Badges 29-33
4 Badges 33-37
5 Badges 36-40
6 Badges 39-43
7 Badges 42-46
8 Badges 50-55
Elite Four defeated 58-63

Secret Base

Secret Base with Standard and Color statues

Similar to Pokémon Diamond, Pearl, and Platinum, the player is able to create a Secret Base within the Grand Underground using a Digger Drill. However, unlike the previous games, the Secret Base can only be decorated with statues and pedestals to place them on.

Statues can be obtained from Stone Boxes. Stone Boxes can be found by digging, similar to spheres and fossils. There are two kinds of Stone Boxes, the common Pretty Stone Boxes and the rare Gorgeous Stone Boxes. There is a box for each type.

Standard statues are obtained from Pretty Stone Boxes, while Color statues are acquired from Gorgeous Stone Boxes. Color statues appear to be made of jade and seemingly depict Shiny Pokémon, due to the statues' names having the shiny symbol next to it.

Each statue placed in the Secret Base increases the chance of encountering a Pokémon of the corresponding type in Hideaways. Only the type with the greatest number of statues of the corresponding type will have a boosted effect, which is indicated by the color of the orb placed next to the entrance of the player's base. This "Statue Effect" is increased for every statue of that type that is placed in the player's Secret Base. If the Pokémon has two types, the primary type of the Pokémon has a greater effect than its secondary type in determining which type has a boosted effect. Hence, if only one statue of a dual-typed Pokémon is placed, the boosted type will correspond to the Pokémon's primary type. Furthermore, larger statues and Color statues provide a greater effect. Up to 18 statues can be placed at one time.

A player's chance of finding a Gorgeous Stone Box can be temporarily increased for four minutes by collecting 40 Diglett that can be found scattered throughout the Grand Underground. Each Diglett counts as one towards the tally, while encountering a Dugtrio counts as three. This count is reset when the player leaves the Grand Underground.

The size of the Secret Base can be expanded by exchanging spheres with one of the merchants in the Grand Underground. Like in the original, a player can only have a single base at a time.

Merchants

Spheres can be used to exchange for pedestals and various items, such as TMs. There are three types of merchants in the Grand Underground:

  • Small sphere merchants allow the player to purchase additional Digger Drills, small or medium pedestals, and TMs which change daily.
  • Large sphere merchants who offer large or extra large pedestals, and a different set of TMs.
  • An item exchange merchant, who will give spheres in exchange for items that can be dug out. Additionally, he can also be paid to expand the player's Secret Base.
Number of spheres required Expansion

Blue Sphere S ×60
Green Sphere S ×60
