Hello. I have a question about gen 3.
Basically, I'd like to know if there are any known graphical glitches regarding shiny Pokémon/Pokémon colors.
I would like to know this because years ago I found a black tentacool near route 124 in Ruby and as far as I know, a shiny tentacool is like a greyish blue and green. Years after that I transfered it to Diamond and it was just a regular tentacool in there.
The same happened to a friend of mine that found a red geodude in Magma's lair in Emerald, but that fucking faggot didn't had Pokéballs to catch it.

I don't have any pics or anything, but would like to know if anyone has seen something like this.
