Steven Stone's Letter

***uming that you've already rescued Peeko, head south from Rustboro, through Petalburg
Woods, then talk to Mr. Briney in his house on Route 104. You'll then sail south to
Dewford Town.

Steven Stone is waiting in Granite Cave, north of the city. Flash is helpful in reaching
him (though not completely necessary). The HM itself can be found by talking to the Hiker
immediately inside the cave, and the Gym Badge from the Dewford Town Gym is required to
use the HM move.
