Vivian is a cream colored wolf that bears a resemblance to a German Shepherd, a breed of dog that is similar in appearance to wolves. Her ears are burnt-orange on the inside. She has a gray muzzle that matches the tip of her hands, the tip of her feet, the tip of her ears, and the tip of her tail. Her large, slanted eyes wear blue eyeshadow, with eyeshadow being a common feature found in villagers with the snooty personality. The back of her head is a pinkish brown color.
Vivian has a snooty personality, meaning that she will appear rude and snobbish to the player at first, finding small things to criticize them and other villagers on. She will get along with cranky and other snooty villagers, but will be annoyed/angered by lazy and jock villagers, both of whom conflict with her lifestyle. Additionally, peppy villagers have the tendency to call her "old" or "boring" while speaking to her, which will quickly make Vivian angry.
