Isle of Armor Diglett locations: Challenge Beach
Challenge Beach has nine Digletts in total throughout an area that isn't particularly big.
As you enter Challenge Beach from the Courageous Cavern, the first Diglett is on the edge of the beach, in the corner by the wall.
A few steps up from the beach is a gap between two rocks. The next Diglett is against the smaller one.
Then the third Diglett is round the other side of the big rock.
Go past the two patches of tall grass and the berry tree in the middle to find Diglett number four in the corner by the river bank.
Cross the beach next and the furthest along standalone rock has a Diglett at the base.
At the far end of the beach, there's another Diglett in the corner.
Go down the path towards the Tower of Water and you'll find another Diglett behind the stone block on the right-hand side.
Go back towards the beach and head up the slope. Diglett number eight is overlooking the ocean.
Go behind the tree right next to the previous Diglett to find this one in some shrubs.
