How do you evolve a nidorina Pokemon Silver?

Answer 1

Nidorina evolves when you use a Moon Stone on it. You can do it at any level you want, but I recommend you do it before it reaches level 23. That's when Nidoqueen learns Body Slam. Nidorina only learns Tail Whip, Bite and Fury Swipes so its not a big deal.

Answer 2

Give it a Moon Stone.

Answer 3

u cant.
