>>42942129The female Nidos are lesbians.
Nidoran is still in denial about it, so she breeds with male Nidos and has purple as her shiny color.
Nidorina knows deep down, but she won't show it on the surface, hence still being purple in her shiny. When she gets put in the daycare with a male Pokemon, she just says she's not in the mood or has a headache.
Nidoqueen is out and proud. She makes herself as hideous a green as possible because she no longer cares about being desirable.
