Invasion of the Ferb Snatchers

After an all night science-fiction movie marathon, Candace is convinced that Ferb is an alien and gathers evidence to prove it. The boys admit that they are doing something for an alien but that Ferb is not one. Her relief turns to excitement and then to frustration when her plan to bust her brothers is compromised by the alien disguised as Mom. Meanwhile, Dr. Doofenshmirtz is trying to sell an evil “-inator” under the guise of it being a cleaning device.

Episode Summary
Candace was annoyed when she heard screaming. It turns out that Phineas and Ferb were watching a sci-fi movie about aliens. She later begins to suspect that Ferb is an alien after she heard him talking in a weird way (Ferb was talking to his cousin from Scotland). Also when she saw his head being ripped off (was just Ferb fixing a power cuff link). And she becomes paranoid and begins to look for proof that Ferb is an alien.

Meanwhile, at Doofenshmirtz Evil Incorporated, Perry is disguised as an evil scientist. He then gains access to Doof's lair and sees his latest creation; The-Wrapped-Up-In-A-Nice-Little-Bow-Inator. Doofenshmirtz then asks Perry if he's wondering what it does. Doof explains and tries to sell it to him. Perry then takes his disguise off. Doofenshmirtz tries to hit him with his bat but Perry turns on the treadmill causing Doof to hit the box of baseballs. They then begin bouncing all around the lair, causing the ray to shoot random things. Doof then tries to throw a chair at Perry but when it is about to hit him the ray hits it and boxes it causing it to bounce off Perry harmlessly.

Back on the ranch, Candace shows Phineas her evidence. Phineas responds negative, and takes Candace with him to confirm with Ferb. Phineas and Ferb then explain to Candace that there's nothing to worry about. Candace, in epiphany, runs into the kitchen to bust them.

At Doofenshmirtz Evil, Perry kicks one of the boxes at Doof, into his mouth to be exact, and the ribbon comes off, causing the contents inside to expand. The force of the expansion makes the Wrapped-Up-In-A-Nice-Little-Bow-Inator go flying across the room leaving perry running to catch it. Doof, now immobilized curses Perry. Perry then jumps onto the Inator just as it falls off the building. On the way down perry presses the button on it causing Doofenshmirtz Evil Incorporated to get wrapped up in a nice little bow. Perry then jumps off the ray and escapes.

Just before it is destroyed the ray fires into the air, hits a satellite, and deflects right onto Phineas and Ferb's landing pad, causing it to fold up just as Candace brings Mom to see it. When it isn't there, A completly heartbroken Candace then repeats a direct quote from the movie - "But it was all right here! Oh, why did I think anyone would believe me? I was a fool!! A fool!!"
