So, wait... Did you seriously just say "I don't care what the game says, this is how DnD and Tolkien put it, so that's how it is."
If the game defines a cyclops with wings, are you going to ignore it as it flies over your walls?
Also, why the hell is Tolkien (one individual) and DnD (one money-hungry franchise) able to define things like that? A big part of fantasy, perhaps the biggest and only part, is that a huge chunk of it is imagination. If you're allowing one person or one board game to limit your views, then you're doing a serious discredit to yourself and to gaming as a whole. You should, literally, be ashamed of yourself. I'm not just saying that to be cute either. If you have sunk so low that you gobble down whatever one person said and spout it as solid truth, then you are living in one of the worst ways imaginable. Tolkien doesn't matter. Tolkien was one guy who wrote a popular book series and that should NEVER allow anyone to have that much sway over your opinions. He was just a guy, born raised and died like anyone else, but people assign him a godlike status because he made fantasy into mainstream. Same with DnD. Great game, sure, but it's just a game. The rules and the species and descriptions were written by someone sitting in a studio, they weren't hand-delivered by the Fantasy Deity and set in stone as "this is the only way fantasy exists".
You're free to disagree with us. Kobolds don't have to be cute for you. But for you to say "it's impossible for kobolds to have fur" is the most blatant pile of BS that I've heard in the longest time and you should REALLY try to broaden your views a little. My Kobolds are fuzzy and they noserub. Yours don't have to be. You're free to disagree, but you're not allowed to tell me that my view of of things is wrong, not when the entire creature is purely defined by imagination. If this was a real graphical game then you could point and say "those are horns" but you cannot point at a "k" and say "those are scales". DF's utter lack of hard descriptions means that it's up for the player to envision the scenario, but you don't seem to get that at all. You've let a man 40 years dead tell you what to think.
