"One Good Scare Ought to Do It!" is a Halloween episode of the animated TV series Phineas and Ferb.


When Isabella falls prey to hiccups, Phineas and Ferb gather the other children together to help scare them out of her, using a remote controlled haunted house. Meanwhile, Doofenshmirtz sets out to destroy his mentor's hideout, so that no one can discover his secrets, but not if Perry has something to say about it.
