"Terrifying Tri-State Trilogy of Terror" is a Phineas and Ferb Halloween special.


In this trilogy of strange tales, Candace accidentally conjures up a spell that turns her Ducky Momo plushie into a living, breathing doll that is set on stalking her, Doofenshmirtz encounters the inexplicable Giant Floating Baby Head that grants cursed wishes, and Phineas, Ferb and their friends confront a horde of mischievous, evil platypuses set on destroying the town.


Mr. Macabre, owner of the Macabre Book Mobile, tells the audience that he's going to read three stories in the book "The Terrifying Tri-State Trilogy of Terror" that will give them a scare. He is first interrupted by his assistant Renfield, then a boy who mistakes the bookmobile for a food truck and is unhappy when he isn't served. He immediately posts a one-star review of the bookmobile online. Macabre says that "burns". A title card written in blood appears, which Macabre pauses to squeegee off the screen, before continuing. The first tale is about a teenage girl and how dangerous careless words can be.

Ducky Momo Turns Evil

Candace holds her possessed Ducky Momo doll.

Tale One opens with the narrator -- a merchant selling books in a bookmobile. He tells us of the book the "Terrifying Tri-State Trilogy of Terror", then starts reading the first tale, which focuses on the Candace storyline. In her bedroom, Candace is talking to Stacy about the book she's reading, which just happens to be the "Terrifiying Tri-State Trilogy of Terror" book, and tells Stacy of a incantation in the book that supposedly turns any stuffed animal to life. However, the incantation claims that if it is said while in view of the full moon, the stuffed animal will turn evil. Candace jokes about this to Stacy, and reads the incantation aloud. Unbeknownst to her, her Ducky Momo plush toy comes to life, and starts sneaking around. Candace starts to have a wary feeling that someone is watching her, but merely brushes it off. Eventually, she sees the Ducky Momo plush following her, and starts running away hysterically from it. Ducky Momo chases her, and eventually catches up to her. Candace thinks that Ducky Momo is after her and is evil, but then she realizes all he wants is a hug. However, another one of Candace's stuffed toys, Mr. Miggins, coming to life and becoming evil as the full moon shines through the window. Candace screams in terror while hugging Ducky Momo.

Mr. Macabre is aimlessly playing with a pea with his fingers in his Macabre Book Mobile. Surprised to see that someone is there, he quickly recomposes himself and begins the second story about a platypus tries to stop an evil scientist and that every wish has a twist.

Night of the Giant Floating Baby Head

Doofenshmirtz meets the inexplicable Giant Floating Baby Head

Tale Two opens with the narrator texting on his mobile phone. Surprised to see that someone is there, he quickly recomposes himself and begins the second story, which focuses on the Agent P storyline. Agent P goes over to Doofenshmirtz Evil Incorporated to find that Doof has invented a Giant Floating Baby Head-Lure-inator to bring the inexplicable Giant Floating Baby Head to his building. Doofenshmirtz read from the "Terrifiying Tri-State Trilogy of Terror" book that the Giant Floating Baby Head will grant three wishes. The Giant Floating Baby Head floats to the building, and absorbs itself into Doofenshmirtz's finger. Excited, Doofenshmirtz wastes his first wish for an ice tea, as a test -- he quickly realizes his mistake, but it's too late. For his second wish, he begins to wish to rule the Tri-State Area, but Perry whacks his foot and he yells out, "Cheese and crackers", instead of "the Tri-State Area", inadvertently allowing him to rule over any cheese and crackers. Doofenshmirtz sends the cheese and crackers to fight Perry, but then he soon realizes that Perry can simply eat them. Doofenshmirtz takes some time to think of his third wish, since he wants to be careful about how he says it, as to not leave any loopholes. Finally, Doofenshmirtz wishes to be the head of the Tri-State Area. Quickly realizing his mistake, he shouts, but alas, it's too late -- his wish turns him into a giant floating head. Doofenshmirtz curses Perry and the Giant Floating Baby Head.

After the commercial break, the camera catches Mr. Macabre texting on his mobile phone. He quickly starts the final story about five kids in a suburban backyard finding out not knowing what to do today.

Invasion of the Evil Platypus Clones

The gang gets some help from Rusty Bridges.

Tale Three opens with the narrator texting on his mobile phone, yet again. He quickly starts the final story, which focuses on the Phineas storyline. Phineas is reading the "Terrifiying Tri-State Trilogy of Terror" book to the gang in a tent in the backyard. He comes upon a story that warns that spilling grape juice on a platypus will cause it to duplicate and form a evil platypus clone. Buford does so on Perry, disregarding the "evil" part of the warning, and creates an evil platypus. The clone pours some grape juice onto itself, creating more clones. Phineas then wonders how to get rid of the clones, and Baljeet tells him that he knows someone who can help them. Baljeet reveals that he has a "life coach", whose name is Rusty Bridges, a cowboy who owns a cleaning supply store. Together, they realize that all they need to do to defeat the clones is to use soap and water against them. They lure the platypus clones, but then realize that there's too many of them for them to defeat on their own. They get cornered into a grape juice factory, and Phineas, back in the tent, finishes his story, saying that everyone then died a painful death. The group doesn't like the ending, so Phineas then tells them the "Hollywood ending". In this ending, just before the platypuses finish the group off, Rusty suddenly comes to the rescue on a unicorn. Activating a pipeline, he turns on sprinklers that spray soap and water on the clones. Officer Concord, the Juice-Time Juice Box Flavor Cop, thanks the kids for saving his factory. At the tent again, Buford expresses his disbelief in the story, explaining that he doesn't believe in cowboys. He asks the other kids if they've ever seen a real-life cowboy, and dramatic music plays as they all stare at the camera in shock.


The story suddenly cuts to Mr. Macabre trying to pitch his idea for a Macabre Book Mobile to a banker so he can get a loan, but he is repeatedly turned down. After saying "pretty please with a cherry on top", the banker gives in to the idea, and then states that this will be the final loan that he'll give Mr. Macabre.

End Credits

Rusty Britches sings a song on the Flynn-Fletcher house front stoop and trips over them. He blows a dandelion while on the ground under the window and mentions the logo.




  • In the first tale, when Candace is talking on the phone in the window, the "Me, Myself and I" poster is blank.
    • Soon after, when Candace is putting on her clothes, the figure of a heart is missing in the poster.

Isabella's eyes are lit with normal lighting instead of a darker tone

  • In the third segment, whenever Isabella is outside, the tint on her eyes is normal, when it should be darker.
  • When the gang is chasing the clones, for a moment, Phineas' bubble washer becomes transparent.


  • All the stories happen in the same episode, however, not at the same time. Each story is separate from the others, which is a change from the regular format.
  • All the mini-stories are referred to by each main character as the episode transitions from story to story.
  • In the end of the episode, it is revealed that none of the stories actually occurred.
  • The title is a play on Trilogy of Terror. This special could also be a spoof on the Simpsons Treehouse of Horror episodes. Also, the three segments are spoofs of the "Clown Without Pity", "The Monkey Paw" and the "Send in the Clones" segments, respectively. (The last one is the most spoofed, including the part with the Perry clones throwing juice to themselves in a direct parody to The Simpsons episode).
  • The title of the second tale seems to be themed on the title of Night of the Living Dead.
  • The final tale's title is based on Invasion of the Body Snatchers.
  • Isabella says, "They're here", a line uttered in Poltergeist.
  • The spilling grape juice on a platypus is akin to getting a normal Mogwai (Gizmo) wet in Gremlins. Both result in evil clones.
  • The ending of "Invasion of the Evil Platypus Clones" is a reference to the ending of Wayne's World where they try different endings.
  • Mr. Macabre's assistant is named after Renfeld, the first victim in Bram Stoker's Dracula.
  • Buford says, "Zombie bunny don't care", a play on The Crazy Honey Badger's catchphrase, "Honey badger don't care."
  • Isabella's solution for getting rid of the Evil Platypus Clones is a direct quote from Aliens, originally spoken by Ellen Ripley as her solution for ensuring the aliens are all killed.
  • Both Ducky Momo and Mr. Miggins' heads eerily spin like Linda Blair's does in The Exorcist.
  • Candace's doll coming alive and turning evil is a very similar plot to Child's Play.
