While on the
Isle of Armor, you will be given a major side quest almost immediately after arriving on the island. On you way to the Master
Dojo, you will come across an Alolan Diglett hiding in the ground. A trainer will arrive and ask if you could help him find all of the Alolan Diglett hiding across the entire Isle or Armor, a whopping 150 of them to be exact. If you can do so, he will reward you for your time and effort along the way.
In order to find all 150 Diglett apart of this side quest, you will need to keep an eye toward the ground at all times to see their hair sticking out. Within the
Fields of Honor, there are eighteen Diglett to be found. Within the
Soothing Wetlands, there are another twenty Diglett you can find. There are another eight in the
Forest of Focus, and another nine in
Challenge Beach. There are seven Digletts in Brawlers' Cave, eight in
Challenge Road, seven in
Courageous Cavern, and seven in
Loop Lagoon. Finally, there are fifteen Diglett in the
Training Lowlands, three in
Warm Up Tunnel, ten in
Potbottom Desert, eleven in
Workout Sea, seven in
Stepping Stone Sea, six in
Insular Sea, three in
Honeycalm Sea, and eleven on
Honeycalm Island.
After finding five of the Digletts, the Diglett Man will gift you with an Alolan
Meowth. After finding ten, he will give you a Kantonian Slowpoke. After finding twenty and thirty Diglett, he will give you an Alolan Vulpix and an Alolan Sandshrew, respectively. After finding forty, fifty and 75 Digletts, he will give you an Alolan Raichu, an Alolan Marowak and an Alaolan Exeggutor, respectively. After finding 100 Diglett, he will gift you with either Rowlet, Litten or Popplio depending on the
Starter Pokemon you originally chose in
Pokemon Sword & Shield. And, of course, after finding all of the Diglett, he will give you an Alolan Diglett of your own.
