The wolves are described as dark and evil and their eyes are blood-red, symbolizing their lust for blood and death. When the wolves attack, Pitu gets clawed by one of the wolves and the wound turns purple. This symbolizes that the wolves' evil and bloodthirst is contagious, like a virus. However, when the author describes their howl like “laughing or crying children”, this shows that there is a sinister, hidden meaning behind the wolves. Even though the wolves look and act evil, their howl is childish and similar to real emotion, implying that the howl is used to lure people, by tricking them into thinking a child is in danger.
