Proposed Canon

The vampires of Transylvito are a sentient race of humanoids. Transylvito Vampires appear as Men except that they have red eyes with no sclera or pupil, pointed ears, and light gray skin.

Transylvito vampires:

• are not vulnerable to sunlight.^Erf-b1-p093
• may drink blood. (They do not appear to suffer from the hunger associated with many vampire types.)^Erf-b1-p139
• have the Natural Ability of flight^Erf-b1-p139
• Are known to controll and either act as a bivouac for or create Doombats

Speculation

Transylvito Vampires may have a desire or need to sleep in coffins.^Erf-b1-p049
