Made before the movie aired
The Movie will have a Vanessa subplotI think the series as a whole is heading this direction with Vanessa's character, but she seems to be ambiguously moral at best. I figure that, considering the fact that Phineas and Ferb will be facing off against her own Father, there has to be some kind of plot there.
The Movie will not only take place in an Parallel Darker and Edgier universe but an Alternative Timeline.Take a look at these preview images in their official wiki. The boys are the only one still smiling (at least Phineas) because they're the ones from our universe/timeline. In this alternative timeline, somehow the boys (In the second dimension) were killed in their schemes along with Vanessa. Which lead Dr. Doofenshmirtz's Start of Darkness into more of a menacing villain and an Evil Overlord. While Candace, Isabella, Buford, Baljeet, and the rest their friends became part of an underground resistance into stopping Doofenshmirtz.
The Across the Second Dimension movie will introduce not just an alternate dimension Doofenshmirtz...But alternate dimension versions of all of the other characters, including a hopelessly-in-love-with-Isabella Phineas, a more talkative Ferb, and a Perry the Platypus that's...just as badass as the original Perry (because everywhere's better with platypi).
In Across the Second Dimension we will meet evil Phineas and evil FerbAs a logical succession of previous WMG. Evil Phineas and Evil Ferb will deliberately mess with Candace's head, and their inventions will not be for fun, but... well for fun. For very specific kind of fun.
The Big Bad Doofenshmirtz in Across the Second Dimension will be VanessaThey are not specifying the first name after all.
Perry will either die and come Back from the Dead or pull a Disney Death in Across the Second Dimension"Everything's Better With Perry" has gotta be foreshadowing something at least.
Perry will talk in Across the Second Dimension
Doofenshmirtz will become the hero of the Across the Second DimensionI mean the main universe Heinz Doofenshmirtz, and it could be for numerous reasons... maybe he notices two kids (Phineas and Ferb) are about to be killed, or Perry the Platypus, and pulls an Even Evil Has Standards moments on his other dimensional counterpart and saves the day... but then tells Perry afterwards that it was a one time thing only.
The alternate universe in the movie will be a universe where Perry never existedThe first song of the movie is titled "Everything's Better With Perry", and according to this, in the alternate universe Doofenshmirtz rules the Tri-State Area and summer doesn't exist. If we believe Quantum Boogaloo, the only thing stopping Doofenshmirtz from taking over is Perry. And their battles are the only reason that Linda hasn't noticed what her sons do every day. Considering what happened in Quantum Boogaloo, it's not much of a stretch to say that summer was banned over Phineas and Ferb's projects.
AU Perry in Across the Second Dimension is allied with Dr. D.Everything's Better with Platypi, including the side of evil. With Ho Yay abound!
In Across The Second Dimension, Linda and Lawrence never got married.Without Ferb, Phineas ended up as a typical kid with a huge imagination, and Candace, ironically, never really bonded with her typical little brother. Ferb, on the other hand, grew up talking even less than in our universe and was very introverted. Since the family never got together, Perry was never taken in and thus never became a secret agent.
Evil Doofenshmirtz from the second dimension is partially defined by having made direct attacks against his parentsAnd will sing a song to our Doofenshmirtz, explaining exactly why he should too.
Perry's full backstory will be explored in Across the Second Dimension.This came from a response by Swampy to a user's question (Fossy, if I recall correctly) on the Phineas and Ferb Wiki as to whether Perry came from Phineas' or Ferb's side of the family. Swampy said to "Watch the movie this Summer" in answer, implying that Perry's whole story will be revealed, possibly including how he was recruited to the OWCA.
Phineas and Ferb will forget Perry's secret identity by the end of Across the Second Dimension.Because of their memories got erased by OWCA. Hey, that's what they did to Phineas and Ferb's dad.
Perry will be a human for some or all of the movieOr that he will talk in English with Phineas and Ferb.
The reason Alt. Doofenshmirtz will be evil is because he never had Vanessa / never met CharleneThink about it! Who does normal Heinz love the most and would do anything for? Vanessa! Having a daughter taught Heinz how to be loved. If Alt. Heinz never meet Charlene or had Vanessa then he wouldn't know how to be loved by someone and wouldn't lessen up on his evil schemes.
There will not be a Reset Button at the end of the movieWell, someone had to say it. It would shake up the status quo, but there's only so much you can do with the same thing over and over, even if you avert, invert, deconstruct, and zig-zag at every opportunity. It wouldn't necessarily be a bad thing, either, just... different. Not that that would stop Fan Dumb from complaining, though.
Perry has a serious personality because of a Dark and Troubled Past, and will be shown in Across the Second Dimension.Based on a screenshot from Across the Second Dimension, Perry was rescued. It may be that he lost his previous family (platypuses) and was a prey for some hunters, probably wounded that time. He doesn't want that to happen again, so he is really serious on his job as an agent, and will do anything to save the Flynn-Fletcher Family. Or maybe because they've saved Perry after the Dark and Troubled Past.
As a Continuity Nod, Ginger will be the co-pilot in the Beak suit alongside Baljeet.As shown in the Episode The Beak, the Beak suit needs two people in order to operate it (although Ferb was able to control the Beak suit on his own while Phineas went to save Isabella, he still had difficulty controlling it.). So, unless they modified the suit so that it only needs one pilot, Baljeet would need someone else in the suit with him. Although Buford would probably seem like the more likely choice in this situation, This Troper doubts that Buford would want to be in a situation where Baljeet would get most of the credit. As shown in the Episode Isabella and the Temple of Sap, Ginger is shown to have a crush on Baljeet, so The Movie might throw in a reference to this by having Ginger offer to pilot the Beak suit alongside Baljeet. Nope. Co-pilot is Irving.
Our Doof will join Pn F to stop alt. Doof when he directly or indirectly threatens Vanessas' life some how.It would be the perfect way to do an Even Evil Has Standards.
Alt Doof's other eye will be a Chekhov's GunDuring the Villain Song, he mentions that it's in his pouch, and they being up the eyepatch thing alot, from the various promotions we've seen. I'm betting on this theory.
Sentient Vending Machines will save the dayOnce again, during the song, The doof's say they fear that vending machines will take over the world. What better way to bring this gag back, then to have them get saved by them?
Irving will save the dayWhy not?
Alternate Phineas, Ferb, and Candace (or Perry) Sacrifice ThemselvesAt one point in the movie, we see a captured Phineas, Ferb, Perry, Candace, and Doofenshmirtz being lead to the Goozim. How do they escape? Simple. Alternate Phineas, Ferb, and Candace show up and free them. As the 1st Dimension heroes prepare to travel to another dimension with that remote of theirs, Doofenshmirtz-2 sends his robot minions after them. Phin, Ferb, Candy, Perry, and Doof escape while the Alternates fight off the robots and are never seen again—presumably killed in the fight. Or maybe as they are being fought, Platyborg comes to his senses and remembers Phin-2 and Ferb-2 as his past owners and goes to save them, letting them escape as he has his last night against Doof-2's robots.
The Movie will shed some (read: little) light on the Giant Floating Baby Head.There's a blink-and-you'll-miss-it moment in 'Kick it Up a Notch's' video that features an alarming number of the darn things, several times larger than we've ever seen before. Heck, there might even be an entire dimension of them, looking at it.
There will be a Heroic BSOD moment for PhineasEach of the hour-long episodes have had one.
The boys are going to fight crime with perry, but...They are going to realize that in the alternate dimension everything is different and are going to think that crime fighting Agent P. was just the Perry of that dimension.
There is a Total Recall Patch, and Isabella will earn it.
Made after the movie aired
Perry's photos will end up on Phineas's computer and make his have a flashback to the movie.
There was no deeper meaning to choo-choo. Doof-2 was just incredibly spoiled.
At the next Cliptastic Countdown he attends, Irving will bribe Agent P for the photos
Irving and Albert know everything that happened.
Irving, and possibly Albert, already knew Perry's secretIrving's a fanboy. More then likely he knows, and for all we know, Monogram is aware. That's why his memory wasn't wiped. As for Albert...well Irving might have told have at some point.
Irving recorded the whole thing.Not the movie, per say, but carried a video camera and followed the boys around. Who knows? Maybe Irving will eventually show it to the boys.
Everyone's memories of the events of this movie are restored in the Grand Finale.
There will be a sequel and it will be strongly related to Alternate!Vanessa.
Platyborg was not cured of evil.It was just an act to get access to rescuing Doof-2.
This movie WAS a movie to the characters.
Not remembering the events of the movie will eventually turn Phineas evil.
Slash was really Lawrence.
Dan Povenmire and Jeff "Swampy" Marsh (Creators of the show) are tropers.In the movie Phineas mentions that Dr. Doofenshmirtz's lair looks like Ferb's head, which was one of the reasons another troper gave for thinking that Doofenshmirtz is Phineas from the future.
Alternate Doofenshmirtz isn't as intelligent as regular Doofenshmirtz, but has more common sense.Regular Doofenshmirtz's Freudian Excuse inspired him to become really smart to compensate, but at the cost of his common sense. Alternate Doofenshmirtz didn't have as tragic a childhood, so is more savvy.
The OWCA intends to sign on Phineas and Ferb whenever they are able.Aside from the old "too dangerous" line, Major Monogram's one objection to allowing Phineas and Ferb to help Perry is that their insurance won't cover it. Unless the reason all the agents are animals has to do with their insurance. They can't get insurance for agents who are people.
Alternate Doofenshmirtz never married Charlene, and never had Vanessa as a daughter.He was too busy being evil, and being successful at it, to pursue a love-life.
This movie has prequel potentialIf only because it would be priceless to have a scene in which Doof-2 says Perry the Platyborg... RISE!!.
Doof-2 had an horribly abusive childhood which he is repressingA bit of Fridge Horror. The scene in which Doof-2 explains how he lost his toy train. Did you notice that he actually had the Eye Patch when he was a kid? The only explanation is that some adult in his life was very abusive, took his eye out and forced Doof-2 to take his eye with him in a pouch.
"Dr." Baljeet got his doctorate from a mail-order company over the internet.
The silhouette of a shrub isn't just any shrub...it's the alternate universe version of Planty the Potted Plant.Because I am convinced that in the regular dimension, Planty the Potted Plant went on to be one of the finest agents at the OWCA. It wouldn't surprise me if his alternate universe counterpart was even more awesome.
The real reason Doof-2 is so evil is because he never had a child unlike the main Dr. Doofenshmirtz: Think about this, Dr. Heinz Doofenshmirtz clearly adores his daughter, and it brings out his soft caring side. In the parallel universe, the alternate Doofenshmirtz has never had anyone to truly care about. This would, also, explain why we never saw an alternate Vanessa. The toy train was simply a cover.
The last dimension they travel through during Brand New Reality is a Witch's Maze
On a related note, the Incubators have mastered interdimensional travelHence they are literally all over the universe. And on another related note...
Kyubey will try to contract Candace-1And this being Candace we're talking about, I guarantee she will wish to successfully bust her brothers. Whether you're not familiar with Madoka Magica, you will know this is a bad idea because either:
Ferb's secret double life will be a major plotline later in the series.
Doof-2 hates Christmas.Because that's when he lost his Choo-Choo. And that is what changed everything.
Dan and Swampy were aware that there are fan-theories that Perry used to be a human.Probably the reason they've decided to put the mystery figure before they show Perry the Platypus.
Stacy died in the Other Dimension.That's why she doesn't appear and isn't mentioned and why Candace-2 is a Knight Templar Big Sister. She already lost someone she loved.
Linda-2 spends her time hiding in the basement because she once dumped Doofenschmirtz-2.They still went on that date at the drive-in. She's still the one who convinced him to settle for the Tri-state area. She's afraid he'll notice her and come after her, especially after she sees a member of her family doing something they're not supposed to. She's ashamed of herself for giving the idea of settling for the Tri-state area in the first place.
The main Phineas in this movie is from another other dimension.An alternative explanation for his bucketloads of OOC Is Serious Business. To be more specific, his rage at finding out about Perry's double life, and his delight at being kissed by Isabella.
Phineas keeps a wrench with him at all times.Remember when the gang was traveling through the mines to get away from Doof's robot minions, and Phineas pulls that wrench from out of nowhere? He carries it with him wherever he goes, kind of like how Tommy Pickles carries around a screwdriver. You never know when it might come in handy.
Vanessa-2 is a robot built by Doof-2 in order to have the "perfect daughter"It'd make sense, why wait years with a wife to have a child and have them grow up, when you can just build one instead.
Second Dimension Roger doesn't/used to existIt's said that Doof-2 had a way better childhood than our Doof just because Doof-2 lost his train. One of the main reasons Doof's childhood stunk was because both his parents liked Roger better. If Doof-2 doesn't have any of Doof-1's excuses then that either means Roger wasn't born and Doof-2 was an only child or Doof-2 got rid of him later in life.
Doof-2 is more evil because his backstory isn't as tragicCould be related to the theory about how Doof-2 isn't as intelligent as Doof 1, but has more common sense. Doof-1 has tragic backstory on tragic backstory, and is a Harmless Villain, while Doof-2 has one minor one and is actually effective. The difference is that Doof-1 has had most of his spirit, self-confidence and common sense pummeled out of him by his various tragedies, while Doof-2 just had a nudge without the spiritual crippling.
Doofenshmirtz would get along well with the lombaxes.Just a really silly Cross Over WMG, quite honestly. Was I really the only one to jump up and point at my TV upon hearing "Otherdimensionator"? note I know it's just a byproduct of the Thing-O-Matic Theme Naming on Doof's part, but it was too tempting to pass up. Here's to hoping that Heinz doesn't create a time-space singularity.
Vanessa-2 is evil.In the second dimension, Vanessa served a role to Doof-2 much like Azula does to Fire Lord Ozai. She's one of his dragons, but does most of her work far away from him, just in case.
Candace and Candace-2 are alternate-dimension versions of Katniss.They have similar names. Candace-2 has superior fighting abilities and will protect her younger siblings from the corrupt government at all costs. Blonde, friendly Jeremy is Peeta.
The kiss between Isabella and Phineas only existed in Phineasland, and not in the real world.The only reason Phineas reacted the way he did was because that how she imagined he would react. In actuality, nothing happened between the time Phineas, Ferb, and Perry said their goodbyes to when the Amnesia-inator was activated.
How alternate Baljeet became a doctorBasically, with Buford being too busy resisting (and resisting the resistance) to be a bully, he had more confidence. He didn't feel like he was in Phineas and Ferb's shadows either since they were kept inside not doing much of anything, so without that in the way, he had the determination and self-esteem necessary to fully motivate himself and get a doctorate in record time.
The movie takes place the second summer.In the deleted scenes, we see Gretchen manning the present gun from Santa's Sleigh. This possibly means that some or all of season 3 takes place the next year, starting with Rollercoaster the Musical, perhaps.
Slash will either make another appearance, cameo, reference to, or mention later in the series.There has to be an explanation as to how and why Phineas and Ferb (and Agent Perry) got a live concert going on, performing "Kick it up a Notch" with the legendary ex-Guns N' Roses guitarist. (And with Candace & Isabella being nowhere in sight, except for those movie clips in-between.)
Other Dimension Stacy was a POW or went MIAIt would certainly explain her absence and why Other Dimension Candace doesn't have a best friend (besides the fact that's she's too busy for friendship...)
Stacy-2 was at home conformingDuh.
Doof-1 is better at fighting an enemy hand-to-hand than Doof-2While Doof-2 apparently defeated Perry-2/Platyborg a long time ago, he seems to have been depending on his former nemesis and army of Norm-bots to take care of any problem that might occur and likely never has to get his own hands dirty. And since Phineas-2 stated that their Perry vanished a long time ago (and summer itself was outlawed years ago), that has probably been several years since Doof-2 had to fight anyone. Doof-1, however, fights against Perry every single day. He might not win, but there are several episodes where he manages to hold his own for a reasonable amount of time against the platypus. Even if Doof-2 used to physically combat his nemesis prior to taking over the Tri-State Area, he would be very out of practice by this point. This might explain why Doof-2 had so much trouble trying to land a hit on Phineas near the end, even though the boy has never been any type of fight worse than a thumb war. While Doof-2 might be more Genre Savvy than his Alternate Universe counterpart, Doof-1 could beat him in a straight fight.
Doof-2's Heel-Face Turnwon't last. After all, if you (or at least, you claim) become evil just because you lost a toy train, there must've been something seriously wrong you from the get go. While it is what motivated him, it isn't what sparked Doof-2's evil. It's very possible that he was an Enfante Terrible, and considered losing his toy train to be what sparked his turn to villainy. Or Doof-2 became evil specifically because his life was happy. The latter could add a lot of Fridge Horror: the only reason Doof-1 is an Anti-Villain is because of his Moral Event Horizon-crossing parents, meaning the two are Not So Different. Doof-2 may have given up when he got his choo-choo, but that doesn't change the fact he's likely still the same demented person he always was. If he ever appears again, it'll be revealed that he's gone back to evil, since he's got nothing else to do. Doof-2 is The Sociopath, and ultimately he'll find it more efficent to be what he truly is: a freak without a human heart.
This movie was actually the movie Phineas mentioned at the end of Teleporters of DOOM, meaning THAT is the canon!
The "Mysterious Force" is real.That would explain everything!
Phineas was never angry at Perry.
Doof-2 did love his Choo-Choo.Well even without a Freudian Excuse, love still can make you evil.
Candace-2 will become a Memetic Badass in the near futureThis isn't a wild mass guess as much as it is a canonical truth. You know this troper is right.
Candace-2 is a Time LordEvery page needs one. Technically its Time Lady, but I agree with both statements
Ferb is a Time LordAs an alternative to the above guess. It would explain his secret double life that Phineas apparently isn't surprised by, he has a way with (sonic) screwdrivers, and he's British
In the 2nd Dimension, Phineas and Ferb got sent to Smile-Away Reformatory School to learn how to conform.Several reasons:
1. Just because Perry dreamed about Candace dreaming about the place doesn't mean it doesn't exist. 2. Their hair was cut the same way as it was in "Phineas and Ferb Get Busted!" 3. If we're going to assume that this is the same Phineas and Ferb, why would they be so interested in conforming just because some random evil guy took over? They'd still be themselves...and, naturally, the evil empire would feel the need to crush that out of them. 4. Alt-Candace is fiercely protective of them because she doesn't want to see them get brainwashed and broken again—or perhaps because she's afraid that if they snap out of it, Doofenshmirtz will realize that it didn't work the first time and come up with a more permanent solution to his little difficulty...
The entire movie is Perry's dream
Indentured Executive Assistant Monogram sent P&F *and* Perry up to Doof-2's office because he recognized Perry
The reason that losing a toy train was such a motivation for Doofenshmirtz-2 to become evil is that said toy train was his Tragic KeepsakeHell, I even have a whole headcanon for it. It's a bit cliche but I've given it thought. Okay,so he's got the same childhood past as Doof-1- neglected and raised by ocelots and all. And he beared with it, like Doof 1. But he had ONE very close friend that greatly helped him do so. On Doof 2's birthday, that friend gave him a toy train, and on it they swore they would be best friends forever. Fast forward several months. It is the day of the Doofenshmirtz family reunion. The friend is not part of the family by blood,but he/she goes anyway. Doof is being embarrassingly uncoordinated as usual,but his best friend cheers him on. After the game, Doof is humiliated so bad that he runs from the field crying, Best Friend following and trying to calm him down. In his stress,Doof yells at Best Friend to go away. They argue a little,leading to Doof to say horrible,personal things to Best Friend. Then Best Friend is now the one to run away in tears. A few days later, they have not spoken to each other since. Doof feels guilty about the incident at the reunion, so he goes to Best Friend to apologize. Best Friend gives Doof a very happy look and waves him hello(or goodbye...)before he/she gets struck by a car(or some other sort of vehicle in Druelselstein that can accidentally cause death.) However he/she does not die immediately. Best Friend dies in the totally shocked and sobbing Doof's arms,his/her last words being "Remember our Choo-Choo Pact? We'll... always... be friends..." Couple years later, Choo-Choo mysteriously disappears.
Across the Second Dimension was partially inspired by the season 2 arc of the new Doctor Who series (especially the episodes "Rise of the Cybermen", "The Age of Steel" and "Doomsday").
Isabella discovers Pinky's secret Identity during the battle against Alternate Doofenshmirtz's robot army.How are we to know that Isabella didn't fight alongside Pinky offscreen during the big battle at the end of the movie. It would also make erasing her memories of that day just as important as erasing the memories of those who knew Perry's secret.
Isabella is Major Monogram's stepdaughter, thus she is immune to the Amnesia-InatorPerhaps that's why Isabella didn't mind kissing Phineas before the Amnesia-Inator was activated. She'll remember the kiss, but Phineas won't. That's also why we don't see Isabella being surprised that her pet Pinky is a secret agent.
The O.W.C.A. also erased the memories of all other citizens of DanvilleLiterally dozens of people witnessed the robot invasion and the battle that followed. It even got broadcasted on the local news. So just erasing the memories of Phineas and Ferb, their friends, and Doofenshmirtz wouldn't be enough. It would only be a matter of time before they discovered that a robot invasion had taken place and their inventions were used to stop it (from either seeing news footage or hearing it from other people), after which they would most likely try to find out what really happened and why they can't remember it, thus discovering Perry's secret again. The solution: the O.W.C.A. had everyone's memories wiped out afterwards and secured the footage of the invasion.
Doof-1 will become as evil as Doof-2
Phineas and Ferb ended up in a wrong dimensionHere's what happened in the circular multiverse, in addition to the show's normal dimension (in which the movie starts) and the 2nd dimension, there are other two dimensions identical to them some dimensions away in anti-clock-wise order. Let us say the first dimension is A, the second dimension is B, and the duplicated dimensions are C and D.
Sequel will have Charlene as the Dragon Ascendant
P&F were busted pre-movie......but the memories of their mother were wiped by the Amnesia-inator.
Doof-2 is a huge bastard because his parents were bad role modelsWell, it is a Rousseau Was Right series, after all, and this mirrors with Doof-1's Freudian Excuse of his parents being bastards. While he does occasionally wish for their approval, admiring them is probably the last thing he'd ever want to do. Doof-2, in contrast, already had their approval and admired them in turn. And since they were still bastards anyway...
Doof2 was more competent and evil than Doof because one received a head injury in childhood, and the other didn't.Some people have proposed the theory that Doof's ditziness is caused by brain trauma, received from his Abusive Parents. Now, if Doof2 received his evilness upgrade after losing his Choo-Choo as a child, it's unlikely he put up his parents for much longer after that. So, if the brain injury occurred after that split in the timeline, Doof2 would never receive it, explaining how much better at villainy he is than his counterpart.
Phineas-2 and Ferb-2 are boyborgsTheir skin is unusually pale compared with the other habitants of the second dimension. This is why upon seeing their counterparts of the first dimension, the second-dimension Phineas and Ferb guessed that they were being substituted, and why Doof-2 guessed that Phineas-1 was 1-2 years old.
Doof-2 is, was, will always be, a spoiled bratUnlike regular Heinz, Heinz-2 was probably raised rather normally, and lavished with attention. So when he lost his toy train (and he probably lost it after chucking it across a crowded room) he pitched a massive fit, and as he grew older he began to manipulate his parents over the loss of that toy train. Because it was precious to him, and the loss was somehow their fault. And because they could never argue, they let him manipulate him. And then he learned to manipulate others around him, and so on until he took over the Tri-State Area. All over a toy train. In fact, that's probably how he'll eventually get out of prison. They'll let him go because he pouts and pretends to have mended his ways.
Roger Doofenshmirtz doesn't exist in dimension 2Heinz was enough of a terror; the Doofenshmirtz's didn't need another.
Doof-2's missing eye was self-inflictedIt's possible that, once upon a time, Heinz-2 was just as literal minded as Doof. Maybe there was a conversation about cutting your nose off to spite your face and he decided he couldn't do his nose but an eye would work. Or perhaps something about 'you might as well just poke your eye out'. Something along those lines.
Doof-2 is conceited, whereas Doof has crippling self-esteem issuesThese two are alike in only very superficial ways. They like the same stuff but had nothing like the same life and don't actually even share a personality. While Heinz's childhood was lonely, sad, devoid of affection or validation, Heinz-2's was spent being lavished with attention and undeserved praise. He grew up believing he was handsome (hence "That would explain the handsomeness..." when meeting his counterpart), whereas Heinz grew up believing himself to be much uglier than he actually is (hence the pleased response to being called handsome; finally getting some positive feedback for once made him heavily attached to... himself). Plus, remember that Doof-2 first thought they were exactly alike and was pleased to have Heinz as a friend, but upon discovering that he isn't as competent, he began using him and doomed him without a second thought.
Doof-2 lost his eye during his rise to dictator, probably in a fight against Perry or MonogramPeople seem to think of Doof-2's toy train memory as a reliable indicator of how early he lost his eye, but if you look closely (it doesn't require that much looking, really), the flashback also shows the walls covered in his name, as they are in modern-day Danville. As it can be assumed that his home in Gimmelshtump wasn't covered in his name (unless his parents were obnoxious or he himself was massively spoiled), we can probably also assume that his memories of his childhood are slightly clouded by more recent events. He might not properly remember how he looked with two eyes as a small boy, or even how his childhood home looked exactly.
The Amnesia-inatordid appear as a past Doof invention of the week... ...but no one remembers that episode, because it wiped the memory of everyone who watched it.
