get lass dana's number and she will say she has something for you
You get it from lass Dana route 38, Mystery gift, or on route 25.
After you battle and beat the gym
route 38
Go to Ecruteak city. From there, start on your way to Olivine. If you stick to the upper route, you will see a girl. She is Lass Dana. Take her phone number, and she will give you a Thunder Stone after some time. Be patient! You can get Fire Stones from Schoolboy Alan who is near where the Sudowoodo used to be. Take his phone number.
One is given to you by Bill's Grandfather on Route 25 when you show him a Pichu. The other is given by Lass Dana on Route 38 after you defeat her in a rematch. I suspect there are only these two in the game as only two Pokemon evolve via Thunder Stone in Pokemon Crystal: Pikachu and Eevee.
well it doesnt really matter how much times it just get to it at some point so if i were you go home to your mom (in the game) and talk to her not about the money but when it says do you want to switch to daylight saving time keep doing it because an hour passes by and some one calls you so keep doing untill dana calls about the thunder stone. hope this helped!
She should be on route 38
You can get a Thunderstone from Bill's grandpa, Lass Dana (she's on Route 38,) and the Pokeathalon Dome. You can also win it as a prize from the Bug Catching Contest.
You can buy them using Athlete Points at the Pokethlon, win the Bug-Catching contest, or wait for specific trainers to call you and give one to you for free. The trainers that give you stones are: * Schoolboy Alan (Route 36) - Fire Stone * Fisherman Tully (Route 42) - Water Stone * Lass Dana (Route 38) - Thunderstone * Picknicker Gina (Route 34) - Leaf Stone
