Isle of Armor Diglett locations: Courageous Cavern
There are a total of seven Diglett to find in Courageous Cavern, but thanks to the layout of the cave, they can be found in any order. This is the order we found them in, starting from the Fields of Honor river entrance.
The first Diglett can be found immediately on your right as you enter the first main room of the cave, next to a raid den.
Number two is found further down the river, on the bank to the left, by a rock.
Keep following the path and you'll come to the main junction. The third Diglett is by the big rock pillar, at the top of the path that descends.
Go down the path that slopes downwards and you'll find another Diglett behind a rock, next to a wild Druddigon spawn.
Keep going down the path to find a room with three raid dens. There's a Diglett by one of them.
Go back up to the junction and take the path directly opposite. On the otherside of the river will be a ledge with a Diglett on.
Finally, a little further along the same path to Loop Lagoon, the last Diglett is on the left.
