Re: Fire Stone in HeartGold? Fire Stone can be obtained through Bill's grandfather on Route 25 (show him a Growlithe). It can also be obtained from School Kid Alan at Route 36 (he has to call you first), as a Bug Catching Contest First Prize and at the Pokeathlon Dome on Sundays, Tuesdays and Thursdays. If you have the Pokewalker, it can sometimes be found at Warm Beach.
