Chansey isn't obtainable in emerald.
Train a Chansey and will evolve.
Chansey isn't in the emerald safari zone.
Chansey appears on Route 209 and the non-foggy part of Route 210. Also, after getting the National Pokedex, Chansey sometimes appears in Mr. Backlot's mansion.
you can't unless you trade it from another game.
the only way i know of is to trade it from firered
occassionally, Mary and oak's radio broadcast notifies you of a swarm of chansey appearing at route 13.
holly wood no.....really no tho its funny chansey is found rarely on route 14
Chansey can be caught anytime. You should usually go to Route 210 or Route 209 to get it. Very rarely, it will be holding a lucky egg, which doubles Exp. from battles.
you get aerodactyl in a trade first you have to catch chansey and it can be found in route 14 once you get it in route 14 you will see a woman in the bushes walking around go to her and trade her a chansey
First you need a chansey which firered and leafgreen can get then to evolve chansey it needs max friendship with its trainer it will then evolve to blissey.
Since you can't catch chansey you need to trade one from firered, leafgreen or Pokemon xd gale of darkness.
Blissey can be acquired when capturing a Chansey and raising her Happiness to a value of 220, then leveling it up at least once. Chansey can be found in Route 209, Route 210, and in Trophy Garden.
