Spared by the Adaptation: Generally, stories involving Br'er Rabbit and Br'er Fox end with Fox getting caught in his own trap and dying, which naturally doesn't happen here. Granted, he would always return for the next tale.
He could also be a subversion, since in the end he actually DOES step forward and save the day.
Nice Guy: He's the only character in the movie to not be shown having any real character flaws or being rude to people at any point. Given that the movie was trying promote tolerance, this was probably intentional.
