Exactly, and it doesn't help that:
1. Not enough people stick around, so we don't get a lot of input from other people and...
2. Nidos don't get a lot of screen time on the anime, which honestly helps put the Pokemon back into focus for at least a little while. And unless I'm mistaken, there hasn't been a Nido episode since the Johto fillers. And there hasn't been a GOOD Nido episode since the Orange Island mini series.
That's how background they are. :| To be fair, though, I still don't think Rattata or Raticate got an episode proper yet. I swear, if I could afford to outsource to a korean animation studio, I would make a 30 minute Pokemon special featuring Nidos and Rats. In FULL animation (which'll cost more, but I'd only be doing this once, sooooo....). It'd probably make every other episode of Pokemon look lazy, and I may get sued, but I'd be the guy to do it just out of spite. It's how I did everything else. =P
Maybe it should be a Pokemon version of Watership Down. Hah! That would be funny
and worth the money spent. Heck, I'm putting that on the to do list.
Funnily enough, I had a dream last night about an episode of the anime, and it DID have a Nidorina in it, and it was based on the current season. Keep in mind I've only seen one episode of the Diamond & Pearl series, and despite how Nido crazy I may seem, I rarely ever have dreams about Nidos. Here's the weird part (and yes, this is going to sound self serving, but I promise you it's not, it's just the way the dream went): She was a childish, pink Nidorina would looked incredibly cute and defied just about all the normal Sugimori model standards (not that Nidorina follows them anyway), and she also floated around. In fact, even in the dream, someone pointed out that they made that episode because they drew inspiration from (read: stole and didn't give credit to) my character, Charlotte.
Charlotte is this girl here, by the way.
It was almost true, too. I didn't complain in the dream or anything, I was just happy they made a decent Nido episode, and on top of which, made her unique enough to the point where people would take a newfound intrest in Nidos. I was also happy the official guys noticed my site and at least did something special for the Nidos. Yes, a guy can dream. And apparently, I just did.
But, just to be clear, the differences between this pink leviating Nidorina and Charlotte is that pink Nido had a much more excited and bright and happy disposition. She had big wide eyes and although she kept the Nido hooked mouth (i.e. :} ), it was drawn in a way that made he look cuter and more smiley, like Squirtle, but even more happy & giggly than that. She was like the Mew of Nidorina. She honestly looked like something out of fan art, but still legitimate. Also, I doubt the pink Nido had hair, though I can't recall 100%. Then she'd really look fannish.
Granted, this was only about 5 - 10 minutes of the entire dream, but man, the effect it had was awesome. I saw people online already had screengrabs of her as avatars and everything (it was actually because of that I went back to watch the episode, since I wouldn't normally watch Pokemon on my own, anyway). It was just what the Nidos needed.
