Stinky Kobold-wise

So, my players are sniffing the spicy-musky stink coming from the cellar. Now, I happen to know this is kobold musk, but the players don’t know that. That’s what they’re trying to identify with all of the sniffing. However, one player has “kobold-wise”. Would he not recognize that as the smell of a kobold? Of course, he can’t use kobold-wise yet, because he doesn’t know what the smell is. I suppose I could “good idea” it, but that relies on me knowing or remembering that one of the players has kobold-wise in the first place. Is there a good answer for this?
