''The Curse of Candace'' is the twenty-third episode of the third season of ''PhineasAndFerb''.

Candace gets bitten by a bat after watching a popular vampire movie with Stacy and fears that she might be becoming a vampire. Meanwhile, Doofenshmirtz plans to turn Danville into a carbon copy of Gimmelshtump so that it will be easier to take over.

!!This episode contains examples of:
* {{Foreshadowing}}: In shots of her being a "vampire," Candace has noticeable bags under her eyes. This was hinting at the ending where Candace suddenly turns into dust under the sun.
* LeaningOnTheFourthWall: At one point, Phineas looks over to Ferb and says that this summer vacation has "felt more than 104 days."
* ShoutOut: The movie Candace and Stacy were watching is an obvious parody of ''Literature/{{Twilight}}''.
