About
Sibella is a vampire of about 12 years old. She is the pretty one out of the girls, and enjoys rough sports as much as the other girls. She is the most talkative and likes to make puns on words related to vampires, like "fangtastic". Sibella is often the one who runs errands, and is always happy to help. She is close to both Winnie and Tanis.

She has long purple hair, light purple skin, red lips, and green eyes, and her outfit consists of a purple dress with a slit, red high-heeled shoes, and a red belt. Her gift to her father was a "bat robe" (a pun on a bathrobe),She made one for herself too, but fire-proof for Matches. Her father loved it, as it was very useful on rainy nights. When he tried it on in a mirror just the robe showed and not him. Shaggy commented that it was "no reflection on him". Like many vampires, she can turn into a bat.
