Vicki Vampiress
Vicki Vampiress is a vendor on some Magic Town lots. (The default lots she appears on are Vernon's Vault and A Spooktacular Spot.) In addition to selling dragon tears and dragon scales, she sells dragon nests. She also sells Dragon Treats and dragon chew toys, which are things every dragon owner will need. She accumulates garlic, though she doesn't like having it around, and will trade garlic for beeswax.
Trivia
Vicki was perhaps named after one of The Sims's engineers, Vicki Fairchild, who's last name was used as a name of a studio in Studio Town of Superstar.
