The Vampire first attacked when she stole a painting. She then attacked the gang in a greenhouse and stole a Star Orchid. The gang went to Dr. Calamari's restaurant and found the Vampire, but the gang accidentaly locked themselves in a cage and the Vampire stole a bottle of wine.
The Vampire was trying to steal a ruby in a museum called the Devil's Eye. Scooby cut the second net and it fell on her and it was Sheila Altoonian. She was jealous that her looks are fading away while Nan still looks like a teenager. Believing her rival to be a vampire Sheila red a book about the youth juice that will make her young and beautiful forever. She knew how to do gliding skills like a flying squirrel so she dressed herself as a lady vampire to steal the ingredients. Nan arrived and found out Sheila was the Vampire.
Sheila was then taken to jail by Sheriff Bronson Stone.
"Give me that painting!"
"That wine will be mine."

"Let me go! I'll strain you all!"
"Wait, I'm not a real vampire I'm..." (unmasks herself and was Sheila Altoonian)
