Arnold's parents just abandoned him with his crazy grandparentsHis parents were regular neglectful slobs who didn't want him or couldn't handle raising a child. Trying to spare him the pain of the truth (perhaps that his parents are drug abusers or, considering the grandparents, mentally unstable) his grandparents tell him fantastic tales of his parents in the jungle, going so far as to fake a journal etc. If it was drug abuse that led to this, it might account for his head deformity.
Helga also has a crush on...Curly
On the day of Hey Arnold's cancellation, Hillwood City fell into a black hole and turned into San Andreas a few months later after falling out of the black hole. The Hey Arnold cast was reincarnated as the GTA: San Andreas cast.
Hey Arnold and World in Conflict take place in the same alternate Seattle.
Arnold's parents were murdered by La Sombra.
Helga's mother is an alcoholic and/or is being abused by Big Bob Pataki.
If the show is ever revived, Big Bob and Miriam will split up due to Miriam's alcoholism.
The whole CHAM incident with Phil in World War 2 wasn't dumb luck.
Arnold and friends are all in Helga's head, and do not exist in reality.
Lila is Arnold's half-sister.
Gerald's father actually did have some combat experience in Vietnam.
Arnold's father's journal was fake.
Gerald knows about Helga's secret but doesn't reveal that so Phoebe won't be in trouble.
Arnold's parents are still alive, they just abandoned him.
Fuzzy Slippers is related to Socko
Harold is actually Jesus.
Helga can read dreamsIn "What's Opera, Arnold?", she continues Arnold's dream from EXACTLY where his left off. Coincidence? No. She was reading his dreams. If thats not true then...
Arnold talks in his sleepPretty much a seperate theory for how Helga continued Arnold's dream in the episode. Arnold talks, or in this case, sings in his sleep, everything that goes on in his dreams and describes it so anyone near him can know exactly whats going on in his dream. So Helga, hearing him, fell asleep and continued his dream.
Olga is Helga's invention or Helga is OlgaRelated to the "Arnold and friends are all in Helga's head, and do not exist in reality" theory. Miriam drinks and Bob has his naster character because they only have Helga. Helga in her delusions adds also what her family should be with a successful daughter. However, Olga appears to some people in Hilliwood, so Helga is disguising herself as Olga to the others. In the episode "Student Teacher" where Olga teaches in PS. 118, Arnold never talk with her and Helga in the same room... so it's easy to trick the others into thinking Olga is another person.
Arnold parents die of some strange illness or are in a comaThis is pretty sad... but also is a big possibility. Arnold parents go missing after going to San Lorenzo to cure another strange illness. Maybe this time they contracted the dissease, get sick and die. Or maybe they get sick at fall into a Coma. This is why they never return with Arnold.
Eduardo is actually an avatar of Nyarlathotep and is the true Big Bad of the show. He orchestrated the entire backstory and planned on using Arnold to cause the downfall of the Green Eyes in the Jungle Movie.Quite a few people have noted that Eduardo comes off as strangely suspicious in the episodes dealing with Miles and Stella. This could easily be chalked up to just being part of his personality, especially considering that he is their closest friend, but it is entirely possible that he is something far more sinister than he seems. As Nyarlathotep, he was the patron deity of the Green Eyes and provided them with unnatural powers in exchange for worship and subservience. As time went on they either turned against him or he grew bored of them, so he began to plot their destruction. Although he clearly had the power to kill them outright, he desired to put them through such incredible suffering that they would yearn for death. He set to work on a lengthy plan that would ensure a spectacularly fitting defeat for the Green Eyes. The first stage of his plan was to bring in pawns that he could use to orchestrate the destruction of his traitorous followers. Assuming the guise of Eduardo, he surfaced in the United States and searched for possible candidates. He eventually found one in Niles and befriended him in order to earn his trust. After some time passed he told him of San Lorenzo and encouraged him to go there for his research. In a different form, he also arranged for Stella to head to San Lorenzo and orchestrated their meeting. He had specifically chosen someone that Niles would be romantically attracted to, as the final stage of his master plan required a couple to be the harbingers of the Green Eyes' destruction. Once they were situated in San Lorenzo, he needed the Green Eyes to welcome them into their village. First, he sent Niles and Stella on a hiking trip and used his powers to send them plummeting into the waterfall from the mountains, where the Green Eyes would be waiting to save them. Now that the Green Eyes were aware of them, he enlisted the aid of La Sombra, a mercenary treasure hunter, and ordered him to steal La Corazon, an important relic of the Green Eyes. Since Miles and Stella were indebted to the Green Eyes for their help, he had little trouble in convincing them to take it back from La Sombra. Now that they had the trust of the Green Eyes, he needed them to form a stronger bond as a couple. He arranged a honeymoon for them in a resort and orchestrated the entire catastrophe with the lifts to test their strength and bring them closer together through a brush with death. Next, he would do the same by spreading a plague among the Green Eyes: by sending them on a mission to cure it, they would not only get more experience as adventurers and grow in their love, but they would become more revered by the Green Eyes, as well. Next came what would be the most important stage of his plan: he needed them to have a child. Nyarlathotep arranged for Stella to become pregnant, either through continuing to strengthen their relationship and letting it occur naturally or by directly interfering. Once the time came for Stella to deliver, Nyarlathotep led them directly to a sacred sanctuary of the Green Eyes that was located near a volcano. He told them that it was on the way to the hospital, but he needed Stella to give birth in the temple itself, which he knew the Green Eyes would be monitoring from a distance. Finally, everything would come to fruition: once Stella had Arnold, Nyarlathotep calmed the mountain in order to make it seem like Arnold's birth was divine. The Green Eyes who witnessed it reported it to the tribe, and he would eventually become their new deity, replacing Nyarlathotep. As it would take a great deal of time for Arnold to become the central deity of their culture, he allowed Stella and Niles to return to the boarding house with their boy until he needed them again. In the meantime, he monitored the Green Eyes to ensure that nothing went awry with his scheme. When the time was right, he came to see Niles and Stella and told them that the sickness had returned in order to get them to return to San Lorenzo. Whether or not he actually caused another disease is uncertain, but his main intent was to bring them back to Central America. Once they returned, he put them into captivity and hid them away, giving Arnold reason to want to find them once he was old enough. He fell into the shadows after this, monitoring Arnold's growth and the Green Eyes from a distance. Once he felt that Arnold was ready to head to San Lorenzo, he arranged the essay contest and ensured that he would win the trip there, knowing that he would take the opportunity to look for his parents. With Arnold in San Lorenzo, he would manipulate him into unwittingly causing the ultimate destruction of the Green Eyes, who loved him and his parents dearly. In the end, the Green Eyes would fall into unbelievable despair as their savior consigned them to their death, and the malevolent deity would delight in their misery as they withered away. As for Arnold and the others, he would either kill them with the Green Eyes or torture them for his sick amusement. Obviously Arnold and the other kids would stop him during the movie. As for how that happens, beats me.
Arnold's original teacher, Miss Slovak, is a lesbian.She's obviously elderly and unmarried. She also seems resentful that she never found true love. She quits her job to become a professional golfer, and a stereotype of lesbians is love for golf. Word of God says that Mr. Simmons, her successor is gay.
The Pigeon man committed suicide.At the end of the episode, The Pigeon Man. His mistrust of people, caused by the kids wrecking his place sent him over the edge. The ending we saw was Arnold's way of coping with what happened. He jumped into the air and Arnold thought hew flew away with pigeons holding him. That...doesn't make much sense. Plus because of the sunset he never really clearly saw what was happening. If he pieced it together it would be too much to cope with for a kid.
Helga was the result of an unplanned pregnancy.Aside from the parental neglect mentioned several times in other WMGs, take note of the 12 year age difference between Olga and Helga. Seems odd that if Bob and Miriam actually wanted another kid, they'd wait that long to have one. Additionally...
Bob is the father of both Torvald and Big Patty
Helga will marry...Brainy
Almost all the characters are Expies of Peanuts characters.Arnold is a combination of Charlie Brown and Linus, while Helga is Lucy combined with Peppermint Patty. Then we have Lila, who's both The Little Red-Haired Girl and Peggy Jean, Phoebe (perhaps the most blatant Expy of Marcie ever created) and Gerald (Franklin—Black Best Friend of Charlie Brown and Linus, who someimes had little background moments with Marcie, dancing with her and so on.) Rhonda is the snobby Violet, and Nadine is Frieda. Chocolate Boy is Pigpen. Harold's a camp bully. Big Patty is the original Patty—she's got a plaid skirt, and the same haircut. Curly? Well, considering how insane he is...could it be that he's just Snoopy in human form? Not to mention that Craig Barlett has spoken about considering Peanuts a huge influence!
Arnold is the spawn of the devil.His parents' entire relationship was ensconced in disaster after disaster, the perils mounting in the time leading up to Arnold's birth, and then on the day Arnold's born, it's in the midst of a volcanic eruption that ceased once he actually came out.
Brainy's real name is also Arnold.This would give Fridge Brilliance to his crush on Helga. He is only known by his nickname and shows up whenever Helga is ranting about Arnold; although he seems to be a Stalker with a Crush, if his real name is Arnold, then he would think that Helga is talking about him all the time and his feelings are reciprocated. Seems like a perfect misunderstanding for the show.
Arnold is an Aspie.This is mostly from Arnold's willingness to help people, sometimes Arnold imagines some stuff in his world (Like him climbing an ice cream mountain in the beginning of "Heat"), Him understanding Helga, and likes protecting everyone's smiles. He also showed a streak of "No forgiveness" and sudden outbursts (Example being not listening to Iggy after Iggy humiliating him in public in "Arnold Betrays Iggy" and Shouting "This is Ridiculous!" in the episode where his grandma and Ernie argued about the theater).
Arnie is a vampire.Think about it. He has pale skin, is always reading food ingredients (possibly to check for garlic), and loves to count things.
Rhonda and Sid are cousins.Not only do they resemble each other, they are both rather high-strung and can be quite mean-spirited at times.
Eugene is an Eldritch AbominationMaybe the most friendly one ever in the history of cartoons. Open your mind to this theory real quick. Arnold Shortman was partial to noticing an energy unlike everyone else. Helga was typically resentful of him, yet everybody else was passively scornful of his personality too. His unpopularity might be justified. A key factor to my idea is the flooding accident in the school. When the storm came Eugene transcended being The Jinx. Typically an abomination wouldn't be just a danger to itself, but an abomination to anything and everything opposite to a reckless destroyer. Hence the trope. Eugene is a rare exception where the concept of self destruction is a gateway into others. When Harold and Stinky rigged Eugene's bicycle, not that it was ever necessary in the first place, just to see him intentionally be put into an unlucky spot. However; the aftermath wasn't even what the audience expected. Because we never seen the result of such a prank, it was particularly suspicious that even the two major idiots of the show had freaked out to Arnold. That anyone would eak out over Eugene having a major accident. My grand assumption is that Eugene doesn't vocally or physically plot revenge. Instead he haunts those who interfere with the system of typical bad luck using paranoia and extreme guilt or insanity. The episode where Principle Wartz slips on a facial soap carving towards the end has no connection to Sid's stalker-feuding. But a long-waited Karma trigger which Eugene's everyday life relates to, painfully. In fact how similar the soap incident was is even more relevant. Wartz believes that Eugene is suspiciously (there's that word again) clumsy, as if any medical events had been planned. As a whole, Wartz is the only one to have been unknowingly right. If the series was able to be truly finished, Eugene would have been revealed as less than normal. This entire idea would follow up to the aforementioned Black Hole theory.
Grandpa is extremely well-endowed.It may explain why he calls himself "Steely Phil", as well as calling Arnold "Short man" (to demean him). It may also explain the phallus in his face, if you look hard enough.
Oskar was only illiterate when it came to reading English.Oskar is obviously an immigrant. He was able to learn to speak English but never learned to read or write it. Prior to "Oskar Can't Read" he is seen being able to both read and write. Some Eastern European languages use a Cyrillic alphabet, and Oskar can write Cyrillic, read in his native language, but not in English or the Roman alphabet.
Coach Wittenberg's son Tucker is not Tish's child.This would at least partially explain why we never see him in any of the later Wittenberg-and-Tish episodes—it's kind of weird to miss your father's wedding, but significantly weirder to miss both parents' wedding to each other. Presumably Tucker is seen less because he lives with his mother.
If 'The Movie' did better we would have gotten a sequel where Arnold goes on an adventure to find his parents.The jungle special seemed like a teaser for something like this, and he would have found them in the protection of the mysterious Green Eye tribe all these years. Fridge Horror means that Arnold and Stewie, both football heads, are related so Herbert is attracted to a blood nephew, Stewie's brother Chris!
Diego Armando and Mia Fey are Arnold's parentsGodot and Mia had sex the night after Mia's first trial. Mia was pregnant with Diego's child when he was poisoned by Dahlia. The time that elapsed between Phoenix's murder accusations and Mia's death had to have been more than a year. That's plenty of time for Mia to deliver the baby and send it off to Godot's father because she couldn't financially support baby Arnold (lawyers don't make a lot of money in the Ace Attorney universe if the games are to be believed). Now makes since except two things, Arnold and his Grandpa doesn't seem to have Brazilian blood. This is easily explained, perhaps Grandpa had an affair with a foreign woman and got her pregnant and Grandma just forgave him and helped him raise the child because the mother probably couldn't take care of it. That type of logic being used, Arnold probably only has 1/4th Brazilian genes in his blood so the nationality isn't exactly visible on him. The other issue is that apparently there's a journal that detail Arnold's parents as some sort of people that explore a jungle. this journal is simply a fake document to protect him from Dahlia.
Helga as Cecile will appear in TJM.
The show takes place in Washington State.Craig Bartlett stated in an interview the show takes place in the Pacific Northwest, and the city's based on Portland, Seattle, and Brooklyn. The real life Skookumchuck River runs through Arnold's city, and is located in Washington. The real life Pig War took place between British Columbia and Washington, and at the end of "Road Trip" Miriam and Helga are seen driving home complete with a Welcome to Washington sign. Arnold's grandpa also once said he worked on the Grand Coulee Dam as a kid, which is also in Washington State.
Arnold lives in Gotham City.The Sewer king in Hey Arnold is the same one as the one in Batman: The Animated Series. After his encounter with Arnold and Gerald he went even nuttier and decided to start kidnapping children. The reason you never see Batman out and about is because Arnold actually lives in one of the few decent neighborhoods and most of Arnold's adventures occur during the day anyway.
Ernie Potts, the short guy in Arnold's boarding house, is Italian American.He resembles Danny De Vito who has Italian ancestry, he has an East Coast accent, and even says Oh Marone an Italian expression in one episode.
The show was originally supposed to take place in the 1950s or 1960sLike The Simpsons WMG, it was supposed to take place during the creator's childhood. Evidence that points to this are the cars, the TVs, the jazz soundtrack, and the fact that one of the characters is a Frank Sinatra Expy. The show obviously takes place in the 1990s due to beepers, cell phones, video games, and some pop culture references.
Miriam was a WellDoneDaughterGirl, just like Helga.Miriam hints several times throughout the show that she was a lot more competent and skilled than she acts in the show. She mentions she was a champion swimmer and had experience with horseback riding, etc. It is hinted also that she married Bob when she was quite young, only for her to discover it wasn't what she'd hoped. She says to Olga, "No, Olga, don't make the same mistake I did." when Olga tells them she wants to marry Doug (Olda can't be older than about nineteen, and rather na´ve at that). But, there is a possibility that she had very pushy, demanding parents who wanted her to have certain skills (horseback riding tends to be associated with upper classes), and Miriam constantly felt pressured and miserable. She then met Bob, found she liked him and thought it could be her way out, much like how Helga latches on to Arnold. While Bob worked, though, he wanted Miriam to take care of things at home and probably raise Olga, and while at first Miriam enjoyed not having so many expectations put on her and encouraged Olga to be successful, like Bob, she soon started getting increasingly dissatisfied and frustrated. We see in "The Beeper Queen" that even when she's working, although at first Miriam is noticeably happier and more energetic, she soon starts neglecting Helga because of the job, so her drinking problems can't all just be traced back to Bob's overbearing attitude. After Helga was born, she started drinking because she was stuck in this repetitive cycle, on she'd placed herself in from constantly being pressured to be the best growing up. It's likely she doesn't know about the extent of Olga's neurotic tendencies (although she might be partially aware), so with Helga, she doesn't take interest in Helga's achievements because of her drinking, but also because she doesn't want Helga to grow up feeling so pressured and unhappy like she was. But in turn, this leads Helga to feel totally ignored and underappreciated, while Olga is a quivering mess, she just hides it under her perfect fašade.
Arnold really is a Jinx.Pay attention to every episode where bad luck and misfortune affects Eugene. Arnold is always right there. Arnold is the jinx.
Arnold and Gerald are relatedIf you look at Gerald's mom, notice she has a football shaped head. It's been established Arnold's parents are his paternal grandparents, so he got the football shaped head from his mother. Arnold's maternal grandfather could've had an affair or hooked up with a woman before he and Gertie married. If that's the case, Arnold and Gerald are cousins. Notice that (despite being Arnold's best friend) Grandpa is really cool to Gerald, and lets him live in the boarding house with little hesitation in the episode "Gerald Comes Over" He knows the secret and treats Gerald like family
