Pokémon BDSP Grand Underground: What Happens When You Find 40 Digletts

Summary Finding 40 Digletts in the Grand Underground increases the chance of Gorgeous Stone Boxes appearing.

The Diglett counter resets to 0 when returning to the surface in BDSP, requiring players to find 40 Digletts in one session.

Multiplayer sessions help find Digletts faster in the Grand Underground.

While exploring Pokémon Brilliant Diamond & Shining Pearl’s Grand Underground, trainers will occasionally find Digletts and Dugtrios in the tunnels connecting the subterranean caves. These Pokémon can’t be caught, but they leave behind pink sparkles when they burrow back underground. Trainers can collect these sparkles before they disappear, which will increase the meter that reads 0/40 just below the Grand Underground’s mini-map in the top left corner of the screen.

This Diglett meter will keep track of how many Digletts players have run into in Pokémon BDSP, and the rarer Dugtrios will increase the meter’s count by three instead of one. However, like many of the mechanics of the Grand Underground, the meter’s function isn’t explained, leaving players to figure out how it works on their own through exploration and experimentation. Finding 40 Digletts will unlock one of the Grand Underground’s best bonuses, and once the meter has been filled, a message reading “Something good may happen in the Grand Underground!” will appear.

What Getting 40 Digletts Does in the Grand Underground

40 Digletts Rewards In Pokémon BDSP

The Diglett bonus achieved by finding 40 Digletts in the Grand Underground increases the chances of digging up Gorgeous Stone Boxes in the Grand Underground’s many digsites, which contain Shiny Pokémon Statues for players to put on display in their Secret Base. Shiny statues are far more effective at increasing the spawn rates of the types of Pokémon they represent than regular Pokémon Statues, and their unique green color makes them a valuable find for decorators as well.

The Diglett Counter Resets in Pokémon BDSP

However, returning to the surface in Pokémon BDSP will automatically reset the counter to 0, so Digletts found only count toward the current session’s tally and can’t be carried over to future sessions in the Grand Underground. Once the meter is completely full, the bonus will activate, but trainers only have four minutes to take advantage of its good fortune before the meter resets and another 40 Digletts must be found.

Trainers can maximize their time with Pokémon BDSP's Diglett bonus by quitting digging sessions as soon as a Gorgeous Stone Box is dug up, as there will only ever be one box per digsite!

Fortunately, when exploring the Grand Underground with online or local multiplayer, the meter’s count is collective, and trainers can work together to find Digletts quickly. All players who are present in the Grand Underground when the bonus takes effect will benefit from it.

Trainers can also buy a Digger Drill to move their Secret Base in BDSP next to a Diglett spawn site. This will allow them to quickly fill the meter as the Diglett will respawn each time they exit the base.

Is Finding All 40 Digletts Worth It?

Pros & Cons Of Diglett Hunting In Pokémon BDSP

But when undertaken as a single, sustained effort, catching 40 Digletts in the Grand Underground can take a lot of time. It may not be worth doing for every single player, every single time they visit the area, but it does have its benefits.

Firstly, the types of Gorgeous Stone Boxes the player finds are totally random. There's no way to exploit the Diglett bonus in order to boost the chances of catching a particular type of Pokémon, let alone a particular individual. It's entirely possible for players to end up finding a statue that boosts the spawn rate of a type they have no use for. But at the same time, it's all based on the luck of the draw, and players can always find additional Gorgeous Stone Boxes of their desired types.

But there's no harm in finding multiple Gorgeous Stone Boxes and amassing a large collection of Shiny Statues. Since the bonuses depend on which Shiny Statues they choose to display in their bases, it's ultimately up to the player which type's spawn rates end up getting a boost. The more Shiny Statues they have, the more options available for customizing spawn rates. Players can even mix and match different combinations depending on what they're looking for each time they delve into the Grand Underground.

So, while it may not be worth it to stake out a spot and exploit Diglett spawns to get to 40/40 every single time, players should go after Digletts when they find them. Once they have a little experience, they'll generally catch enough each time they go down to the Grand Underground without even really trying, especially if they're playing with multiple people. The more time they spend in Pokémon Brilliant Diamond & Shining Pearl’s Grand Underground, the more trainers can expect to benefit from this secret bonus - but they should also expect to end up catching way more than just 40 Digletts.
