Based on Tolkien's Hobbits. In the early incarnations of the game, they were actually called Hobbits, until threats from the Tolkien Estate caused a name change.

But at any rate hobbits can move quietly in woods, absolutely quietly. They take a pride in it, and Bilbo had sniffed more than once at what he called "all this dwarvish racket," as they went along...As for Bilbo walking primly towards the red light, I don't suppose even a weasel would have stirred a whisker at it. So, naturally, he got right up to the fire-for fire it was without disturbing anyone. And this is what he saw...
