Isle of Armor Diglett locations: Honeycalm Sea
Honeycalm Sea has just three Diglett to find thanks to the lack of land, in the following locations.
Cross the water directly east from Honeycalm Island and you'll find this small inlet of land with a raid den. The first Diglett is directly opposite the den.
The second Diglett is at the end of the path, behind the TR item.
Hop back on your bike and go to the small sandy island south of Honeycalm Island. This is where the final Diglett can be found.
