In Cerulean City, there is a building next to the Pokemon Center. Enter that building with a Poliwhirl in your party that you don't mind saying goodbye to. Talk to the man in the back of the house, and say yes when he asks you to trade.
No.
You have to trade a type of Pokemon with an old man in Cerulean City to get a Jynx.

No, Jynx is already the highest evolution of the baby pokemon Smoochum. It evolves into Jynx at lv. 30.
Smoochum (sometimes misspelled as Smoochim) is an ice/psychic type of Pokemon. To get one in LeafGreen, you need to breed a Jynx.
Yes, you can obtain a Jynx in Pokémon Emerald, but it is not available in the wild. To get a Jynx, you need to trade with someone who has it, as Jynx is exclusive to Pokémon FireRed and LeafGreen. Alternatively, you can evolve a Smoochum, which is obtainable through trading from those games.

Get a jynx from Pokemon firered or leafgreen then put it in the daycare with a ditto and wait when you come back you can get an egg and when it hatches its smoochum. You can't catch smoochum you need to breed a jynx with a ditto to get it. Breed two jinx (leave in daycare)
No it is not.
jynx ..
To get Smoochum you must breed a Jynx and if you have a Smoochum you must maximize its happiness to evolve it to Jynx. You can migrate a Jynx from Firered or Leafgreen to a Generation IV game like Diamond then use the GTS to trade it to a Generation V game.
