Howard proposed four animals, among which the rabbit and the fox are the 'male and female protagonists.' The Broad-eared Fox had few scenes, but it presented a massive contrast in cuteness: in the script, the Broad-eared Fox and the fox Nick commit cons together. It looked like a three or four-year-old baby on the outside, but in reality, it was an old swindler, modeled after African American hoodlums on the streets of the United States.
Shrews are animals that look very similar to mice but are not related to them at all. They survive by eating earthworms, insects, and the like. Being one of the earliest placental mammals, they arose in the Cretaceous period. The shrew is the smallest mammal in the world, only a few centimeters long and weighing no more than ten grams, making it extremely vulnerable. Yet, in the script, the shrew played the role of a boss, with a group of strong Polar Bear thugs under its command, modeled after The Godfather.
