goldenrod city and kanto by cerulean city(route 25)
Go to the Pokemon center in Ecruteak City and talk to Bill. Then go to his house in Goldenrod City and talk to him. Remember you have to have an open space in your party.
There is not mention of anything being behind the hole in the wall of Bill's seaside house on Route 25 in Pokemon Crystal.
Bill's grandfather lives in Bill's old house on Route 25 which is above Cerulean City.
after you get the macine part and return it you go up to bill's house
In the Pokemon center in ecruteak city When you enter the ecruteak city Pokemon center bill will come down from upstairs then he will return to his house in goldenrod city
You get it from Bill in Goldenrod city (his house is south-west of the Game Corner), but you have to talk to him in the Ecruteak Pokemon Center in order for him to be there.
Oddish Try finding one in route 24 but they only come out at night
you would have to go look for her she is out of town where bill's house is then you can battle her at the gym.
In Pokemon crystall Bill is the guy who makes the PC system and also likes rare Pokemon
Once you're in the Kanto region, go up the Nugget Bridge and go to Bill's House, just north of Cerulean City. There, Misty will be dating a strange man. Misty will then return to the Gym where you can battle her.
Bill is not in Pokemon Sapphire. He is only in Red, Blue, Yellow, Gold, Silver, Crystal, Fire Red, and Leaf Green.
It's impossible. No. 1: Bill lives in the Kanto region No.2 : You can only get to Bill's house in fire red or leaf green Glad I could help! Ameri23
