I've recently replayed Crystal, again, and I'm almost near the level where my Poliwhirl is ready to evolve into Poliwrath and learn Submission. Problem is... I'm kind of impatient in waiting for Fisher Tully fish up a Water Stone for me to use on said Water-Type. Is there any faster way to get Water Stones from him, because I'm pretty sure the only way to get Stones in the GSC games is to get certain trainers' phone numbers and wait out until they have the Stone you need, except for Sun Stones.
