Explore the revamped Grand Underground or put on a Super Contest Show
The Underground from the Pokémon Diamond Version game has been powered up and is now called the Grand Underground. Here, you can dig up valuable treasure and Pokémon Fossils, create your own Secret Base, and catch Pokémon in places called Pokémon Hideaways. When you aren’t exploring in the Grand Underground, enter a Super Contest Show! Super Contest Shows are popular events in the Sinnoh region, each put on by four performers and their partner Pokémon, who work together to dance and show off their performance skills. You can also adventure in the Grand Underground or put on a Super Contest Show with other players through the local* communication or online** communication of your Nintendo Switch system***!
Walk with your Pokémon, change up your style, and customize your Poké Balls™
Choose a Pokémon that you’ve befriended during your journey to walk along behind you in the game. In the relaxing Amity Square you can walk with up to 6 Pokémon! Depending on the Pokémon, you’ll see different gestures or ways of walking, and when you talk to your Pokémon, it will respond. You’ll also be able to add your own personal style! Choose a variety of outfits and coordinate tops and bottoms. Some are based around Pokémon motifs and others change your hairstyle. You can even use Capsule Decoration to add stickers to customize the effects that appear when your Pokémon comes out of its Poké Ball!
