They got raped by a rampant Nidorina, so ceruleon cave
use a moonstone on a nidorina. catch nidoran female or nidorina in safari zone
in the safari zone at fuschia city.
go to the safari zone, catch a nidoran(female) or a nidorina and use a moonstone (if it's a nidorina)
You can find Nidoran in route 3 (sometimes even Nidorino\Nidorina) and the Safari Zone in Fuchia city.
Clefairy, Jigglypuff, Nidorina, Nidorino
It evolves jigglypuff, clefairy, nidorino, nidorina and skitty.
jigglypuff clefairy nidorino nidorina jiigglypuff-wigglytuff clefairy-clefable nidorino-nidoking nidorina-nidoqueen hope i helped
The only way to evolve Nidorina to Nidoqueen or Nidorino to Nidoking is using a Moon Stone on either of them, which you can find throughout the game. Good luck! ~Katie
I've seen Nidorina in the Safari Zone at Fushia City. It would also be easier to catch a female Nidoran (also in Safari Zone but with a higher catching rate) and evolve it.
Goldeen/Seaking, Nidoran/Nidorino, Nidoran/Nidorina and Rhyhorn/Rhydon learn it.
You need to get a nidoran female first which only firered and leafgreen can get trade one to emerald then train it to level 16 to get nidorina use a moon stone on it to evolve it again to nidoqueen.
