yes at places that seem haunted
Go to the game corner the go fight team rocket boss and you will get a slithscope(something like that. Wrong spelling.). Than you will be able to see gasly, haunter, etc. Go to the highest floor by the stairs and fight Marawak. Than go down the stairs.
get a female wabudfet and breed it with gasly bannete e.t.c.
to my knowledge you cant. some one has to trade you a hounter. the hounter will immediately evolve into gengar. you can just trade it between two of your own games, ifyou have access to two DSes
well, you hav to get a haunter (get a gasly and evolve it at lv.16 )and go to the top of the lighthouse.when you get to the top, go to the medal gate, press a and the ampharos runs off. jasmin e sould go out and talk to you. good luck.
Sprout tower & bell tower (Take note they are not the only places)
