I really don't want to spend my time going through Pearl for a Smoochum then trading it if there's a way to get it in SoulSilver.
You can get it easily in SoulSilver by breeding a Jynx with a Ditto or any male Pokemon from the Human-Like Egg Group. Jynx can be caugth at the Ice Path or the Seafoam Island. Sources: http://pokemondb.net/location/johto-ice-path http://pokemondb.net/location/kanto-seafoam-islands
