How to access the Grand Underground
If players want to catch some of these Pokemon in the Grand Underground of Brilliant Diamond and Shining Pearl, they will need to know how to access these special Hideaways.
One will receive the Explorer Kit item in Eterna City. An old man will give it to them in a house next to the Pokemon Center. Players can't leave the city or progress without learning how to use it.
Once players have the Explorer Kit, they can access the Grand Underground to start building their base or visit Hideaways. Hideaways are tucked away rooms that one can enter while roaming the Grand Underground.
Players can just walk into the entrance and find their character in a Hideaway. They will see a variety of different types of biomes as they explore along with plenty of the creatures above to add to their Pokedex.
