There are 11 Diglett to find in the Workout Sea.
Alolan Diglett #1
This small sandy island is the furthest south on the map. If you are looking out at the ocean from the Fields of Honor beach you should be able to spot the rock the Diglett is hiding by.
Alolan Diglett #2
This Diglett is hiding on a small sandy island. If you can, use Wailord as a reference point as the island is right behind it. Otherwise, if you are looking out at the ocean from the Fields of Honor beach you should be able to spot a large sandy island with only a Pokemon Den on it. This small, flat island is to the left of it.
Alolan Diglett #3
This Diglett is hiding by a rock on an island filled with Ditto. If you are looking out at the ocean from the Fields of Honor beach you should be able to spot this island by looking leftward. The island has three trees.
Alolan Diglett #4
Like with Diglett #3 this Diglett is hiding on an island filled with Ditto. If you are looking out at the ocean from the Fields of Honor beach you should be able to spot this island by looking leftward. The island has three trees.
This Ditto is hiding in the sand on the shore near the most southern point of the island.
Alolan Diglett #5, #6
Like with Diglett #3 and #4, Diglett #5 and #6 are hiding on an island filled with Ditto. If you are looking out at the ocean from the Fields of Honor beach you should be able to spot this island by looking leftward. The island has three trees.
Diglett #5 is hiding in the shore near the northern point of the island. Use the tall grass and cave as reference points.
Diglett #6 is slightly to the left (if looking towards the water and cave). It is hiding with two pebbles in front of a tree.
Alolan Diglett #7
This Diglett is hiding on the island where you can turn Galarica Twigs into a Galarica Cuff. The island is the closest island to Stepping-Stone Sea and is opposite the secluded beach with a Berry Tree. If you are looking out at the ocean from the Fields of Honor beach you should be able to spot this island by looking rightward. The island has a large archway.
The Diglett is opposite the lady who turns the Galarica Twigs into a Galarica Cuff. It’s easy to miss as it’s on the surface above you. You can’t climb up there so speak to the Diglett from the ground below.
Alolan Diglett #8
This Diglett is on the same island as Diglett #7. Again, that is the island where you can turn Galarica Twigs into a Galarica Cuff. The island is the closest island to Stepping-Stone Sea and is opposite the secluded beach with a Berry Tree. If you are looking out at the ocean from the Fields of Honor beach you should be able to spot this island by looking rightward. The island has a large archway.
The Diglett is opposite the Pokemon Den near the center of the island. It is hiding by some flowers.
Alolan Diglett #9
Diglett #9 is on the same island as Diglett #7 and #8. Again, that is the island where you can turn Galarica Twigs into a Galarica Cuff. The island is the closest island to Stepping-Stone Sea and is opposite the secluded beach with a Berry Tree. If you are looking out at the ocean from the Fields of Honor beach you should be able to spot this island by looking rightward. The island has a large archway.
The Diglett is hiding on the shore at the back of the island (through the archway past the Pokemon Den).
Alolan Diglett #10
Diglett #10 is hiding on the secluded beach with a Berry Tree. To reach this beach, when you exit Armor Station head right and follow the cliff along the narrow grassy path. Once you reach the water continue following the cliff while riding your bike in the water. Shortly after you’ll reach the beach with the Diglett and Berry Tree.
Alolan Diglett #11
This heart-shaped island is close to the shoreline at Fields of Honor with a Pokemon Den on it. Diglett is hiding in the sand in the middle of the island.
