History NightmareFuel / Phineasandferb

** There's also Rodney's willingness to throw the Earth into a new Ice Age is kinda disturbing, even going so far to destroy the reverse switch and self-destruct button on his latest machine to ensure that he would accomplish that, which would endanger the entire world population. Fortunately, Doofenshmirtz's HeelFaceTurn was enough to prevent it from happening as he holds sheer disgust over Rodney's plot; even Perry too shares Doof's feelings over the event, as evidenced when [[EnemyMine he personally helped Doof in taking down the machine to save the Earth and foil Rodney for good]].

"NO! No we're not!"

* Klimpaloon is unnerving. The knock-off Klimpaloons are horrifying. Not only do they look a hundred shades of wrong, the noises they make sound utterly ''agonized''.

* Doofenshmirtz's PainfulTransformation into a Were-cow was no picnic either. The background music while it happens does ''not'' help.

** The first 'story', following Candace is probably the scariest one. It involves Candace accidentally turning Ducky Momo (as in, [[KillerTeddyBear her doll]]) evil. While that may not sound frightening, we're treated to a [[SarcasmMode lovely]] scene where it gets stuck in a door Candace is obliviously trying to close, and it ends up loosing one of it's eyes, which is still barely holding on by a string, and having a seam ripping open, with stuffing falling out. And then, as the song begins, it simply... draws everything back to it's body. Slowly. It's creepier than it sounds, especially if you listen closely as it happens. Also Ducky Momo spinning it's [[Film/TheExorcist head around]] didn't help things.

-->'''Doofenshmirtz:''' Remember two seconds ago when you foiled my latest plan? ''I do!'' ''[[EvilLaugh laughs evilly]]]''

** This transforms Doof into an evil monster, and Perry is actually scared of him. Seriously!

* When Perry kicks Doofenshmirtz out of his chair, [[NiceJobBreakingItHero this gives him one more bad memory that helps power the Backstory-inator!]]

*** And let's not forget the end. Ducky Momo isn't evil, he just wanted a hug. Why? Because Candace didn't expose it to moonlight, which was the key factor for it being evil. Then the moon comes out and shines on [[KillerTeddyBear Mr. Miggins]] who grows ''claws and teeth'' and sports a horrible expression and ''[[TheFourthWallWillNotProtectYou lunging at the screen]]'' to the sound of Candace screaming. Cue commercial break, then a new, unrelated segment all together.
** Finally, there's the third 'story', involving Perry having grape juice spilled on him (via Buford) which creates an evil, purple clone. The clone, after scarring the kids, pours more juice onto itself to create more clones, and then they spread out throughout Danville causing havoc and [[ArsonMurderAndJaywalking playing tennis]]. In the end, the kids, after trying and failing to wipe out the at least several hundred clones, they end up in a grape juice box factory and end up ''[[FamilyUnfriendlyDeath being ripped to shreds]]'', thankfully offscreen. Of course, it was all just a story and the ending got changed to "the Hollywood ending", but that arguably makes it worse... ''[[CheerfulChild Phineas]]'' wanted the story to end that way.

** His plan with it. Red Skull states he and the other villains aren't interested in conquering the Tri-state area, they are destroying it. He demonstrates the -inator by destroying a hog dog vendor but threatened to increase it's area of effect to hit the entire city, and before the -inator was crushed by the falling space station, he nearly set it off to destroy the city, just to kill the heroes.

** '''[[TheHeroDies Agent P getting infected.]]''' Yes, you read that right. Perry the Platypus, who has gone through another dimension and fought endless times with Doofenshmirtz with little to no trouble, and has overall been shown to be extremely good on the job, [[AndThenJohnWasAZombie is touched by one of the Doof-zombies and is helpless to do anything as he transforms into yet another fusion between Doof and an animal]]. It also highlights the fact that, as pointed out earlier by Phineas, even someone who is a complete badass at hand to hand combat (as many of the characters are) is [[TheWorfEffect helpless]] against the zombies if they are unarmed, because ''any'' physical contact will cause infection. What's worse, ''he speaks''. Perry's infected form goes from his familiar chatter to a growling "Lots of me."

* The Drusselstein Driving Test Waltzis actually quite terrifying given it's so dangerous that Doofenshmirtz barely run over pedestrians and nearly got himself and Perry killed. Speaking of Perry, [[OOCIsSeriousBusiness he is legitimately terrified]] that he secures himself with several extra seatbelts and later writes out his will.

[[caption-width-right:350:[[RunningGag Aren't you a little too old to think this picture is scary?]] [[BodyHorror YES! YES WE ARE!]]]]

** This transforms Doof into an evil monster, and Perry is actually scared of him. Seriously. Take a look.

* Doof's SuperpoweredEvilSide. Seriously. He looks like a scary monster!

* Busting Candace, one of the titular split personalities, makes [[https://www.youtube.com/watch?v=TXCiJ17ceNA this]] inhuman noise at one point. It's unsettling ''in-universe'' too, as the brothers quickly decide that when this is over they will destroy their invention that made the split personalities to prevent it from ever happening again.

* Doof's [[SuperpoweredEvilSide]]. Seriously. He looks like a scary monster!

* Are we forgetting that bit in the end credits with the Kinderlumper looking through young Doofenshmirtz's window?

* The moment when the Death Star is seconds away from being destroyed. For a moment, Phineas and the others are certain their all about to die when it explodes. Remember, most of these people are kids.

* Five words: [[RetGone "Who are Phineas and Ferb?"]]

[[AC:Other]]

* The [[http://phineasandferb.wikia.com/wiki/File:Turning_on_their_creators_1.jpg Phinedroids]] and [[http://phineasandferb.wikia.com/wiki/File:Turning_on_their_creators_2.jpg Ferbots]] are quite terrifying the first time you see them. The Candroid is even more so. There's one particular shot, right after the boys shut down their coffee stand, where they look toward the camera in the ''[[UncannyValley creepiest]]'' fashion...

* The costumes in the live stage show with the big, constantly staring eyes. Not to mention that the heavily stylized cartoon anatomy of the characters overall just doesn't really... [[UncannyValley fit]] when it comes to a live action adaptation.

[[AC:Non-canon]]
* Like the stage costumes, this image of [[http://img04.deviantart.net/3906/i/2014/147/c/a/phineas_and_ferb_in_real_life_by_danielplackey-d7k05i5.jpg Phineas untooned]] falls straight into the UncannyValley.

* This episode is creepy on ''so'' many levels. That's right, Phineas and Ferb deliberately created an AI smarter than them to trap them repeatedly - a new trap every time they escape one - so that they may ''never'' be able to get out. The mallet they built to smash it from the outside in case of the inevitable emergency? Doesn't work. And ''then'', when they finally get into their backyard (by tunneling through the ground), the thing traps them with a shield and announces its plan to ''cut off their air supply''. The happy ending? The shield expands to include the entire galaxy. Cold comfort.

* The aliens's plan. To begin, they trick the boys and their friends into switching minds with them, trapping the kids in prison. Then, in order to make sure they can't be sent back, set the boys's machine to self-destruct, meaning they were totally willing to leave the kids in jail. Only Phineas managing to warn Candace saves them.

* How about the cause of all this mess: the Power-Drain-inator. Doofenshmirtz created it to drain Roger's power of mayor and did not even realize that it could actually be dangerous if used against a different target. Such as [[ComicBook/TheAvengers Earth's Mightest Heroes]] and ComicBook/SpiderMan.

** When Phineas, Isabella, and Ferb are going to activate the vortex sprayer to spray all the Doof-zombies back to normal with water, the Doof-zombies ''climb the pillars of the water tower'' towards them! It gets worse when, just as they are about to be touched, Ferb [[HeroicSacrifice sacrifices himself so they can go]] by kicking them away...and is then touched by one of them, shortly turning into a Doof-zombie in front of Isabella and his step-brother!
