underground_(sinnoh)
The Underground is a large area comprised of many corridors located underneath the whole region of Sinnoh, accessible in Pokémon_Diamond,_Pearl_and_Platinum.
Multiple players can interact in the Underground via the DS Wireless Communication.
Some activities available in the Undergound include:
* Digging items such as fossils and evolutionary stones from the walls.
* Building and decorating a Secret_Base.
* Finding the Secret Bases of other players and capturing their flags.
* Placing traps on the ground, which often negatively affect the movements of players who step on them.
