Episode Summary
On Halloween night, Phineas and Ferb are finishing up the finishing touches to their epic Halloween party. Phineas then wonders how many Halloween episodes they've even had. Ferb says ten counting this one. Phineas is impressed. He thinks they should stop breaking the fourth wall and wait for the guests to arrive. Then he wonders where Perry is. Perry enters his lair through a Jack O'Lantern. When he enters, the lights are turned off and he wonders why. Just then, weird music plays in the background. Suddenly, Monogram gives Perry a jump scare while dressed as a creepy, animatronic animal. Monogram and Carl start laughing because they should've seen the look on his face.
