A lot of PetVille's Twilight Dusk release is outdoor decor that can only be used in the yards, but there's still new clothes, walls and floor styles. Also, if you head to the game's Premium Showroom section, you can buy PetVille-styled versions of the Twilight Dusk characters for your pet's home. The following is the rest of the cast, not including Edward (or Petward Culven, as the game calls him) since he appeared before the weekend.
Another adopted sister of Edward is Rosalie Hale, who's been renamed Josalie Tail (costs 27 Pet Cash). In Twilight, Rosalie grew up with everyone telling her how beautiful she was, and she's always been mad at Edward for not being attracted to her. PetVille has chosen to represent this by having its version of Rosalie whip out her compact mirror to gaze at herself.
Now I know I said no more Edward, but this one screenshot was just too cute to pass up. Like the Howling Jaycub Grey, this version of Edward, called Petward Culven and the Apple (for 35 Pet Cash), is only available for the next 6 days. So grab him while you still can!
