"The Curse of Candace" is the twenty-third episode of the third season of ''WesternAnimation/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:
* DidntThinkThisThrough: Doofenshmirtz testing his Gimmelshtump-Inator on his bathroom seemed like a good demonstration...until the time came where he had to use it.
* ExhaustedEyeBags: Candace has these after becoming a "vampire".
* {{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.
* InstantlyProvenWrong: Phineas tells Candace that she's not a vampire & tries to prove that by removing her hoodie & her glasses. Guess what happens.
* 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}}''.
** When Candace is bitten by the bat, she spins around on the floor running, a la The Three Stooges.
