I happen to be throwing the biggest, baddest, Halloweeniest bash ever!


When Vanessa learns that Doofenshmirtz has inherited a Drusselsteinian castle right next door to her she seizes the opportunity to throw the biggest Halloween bash ever. The whole town is there, including Phineas and Ferb, who act as the event's party planners and DJs. Meanwhile, Doofenshmirtz enlists Perry to help him find a large, hidden treasure that his Great Aunt has placed somewhere within the castle.

Episode Summary

The story opens at the Flynn-Fletcher House, where Lawrence is dressed in a gorilla costume making a jack o'lantern. Phineas tells Dad that he, Candace and Ferb are off to a Halloween party in a castle where they will work. Linda arrives in a nurse outfit, and Lawrence puts the gorilla head on, mock-scaring Mom in the process.

Meanwhile, Agent P jumps into his lair via a pile of leaves quickly cleared by a leaf blower. In his lair decorated for the holiday, Major Monogram, dressed as Carmen Miranda, informs Perry that he has to work tonight keeping an eye out for Doofenshmirtz and Carl enters in a variation of the outfit. After saying that's what he looks like in the costume, Monogram tells Carl he can have it, and will look into getting another costume.

Vanessa is on the phone with the Major's son, Monty, doing a bit of freelance work at a black-tie party, telling him about the party she is throwing in a castle that her dad inherited via a split screen. After saying she'll dress as a vampire queen, Monty says he'll be dressed as The Scarlet Pimpernel. After hanging up, he tells Agent M that he's alone from there.

At the Doofenshmirtz Evil Incorporated building, Doofenshmirtz gives out candy to trick-or-treaters, including Perry, who is dressed as a ghost. After Perry twists Doof's arm, the doctor says he has no -inator, but inherited a castle from his Great Aunt Henrietta Hawkenschpit, who liked Heinz more than Roger.  Inside that castle is a major treasure, and suggests that Perry join him searching for the treasure on a map with clues.

At the castle, next to the D.E.I. building, Vanessa welcomes guests, including Lacie, who really isn't in a costume, and Candace, who is dressed like Vanessa, as is Stacy, who says she'll change her costume.
