It says in the books. Vampires, according to Mormon lore, are rock hard, cold as ice, sparkle in direct sunlight (but not any other light), don't have fangs, do have "venom, and sound like metal when you tear them. They have black eyes when they're hungry, red eyes when they drink people, and golden eyes when they only drink animals so as to reflect their hearts of gold.

Jeez, Shiny, keep up.
