History WesternAnimation / HeyArnoldTheJungleMovie

** Phoebe clearly ships Arnold and Helga together.

* ParentsKnowTheirChildren: [[spoiler:Miles and Stella instantly recognize Arnold despite the fact he was an infant the last time they saw him.]] Then again [[spoiler:Arnold still looked mostly the same when he was a baby.]]

* RealAfterAll: [[spoiler:The ending is proof that Arnold is not dreaming- he finally found his parents at long last. What makes this so striking is that he's still dealing with fears this isn't the case, as he keeps having nightmares about not finding them.]]

* GrandFinale: ''The Jungle Movie'' serves as the final conclusion to the series, bringing an end to Arnold's journey in finding his lost parents.

* AllJustADream: The movie begins with Arnold seemingly finding his parents at long last, only to reveal that it was only a dream. [[spoiler:The movie's ending makes it appear as though all the events of the movie were also just a dream, [[SubvertedTrope only to subvert it and reveal that Arnold really did find and rescue his parents.]] From the way things look, Arnold had been going through the exact same routine over and over again up until the trip was anncounced.]]

* ClingyJealousGirl: Helga, Doi! She gets jealous when the Princess of The Green Eyes takes Arnold's hand and not-to-subtly tells her to back off.

-> "Pure of heart, that's Arnold. And that's why he deserves to win the trip to San Lorenzo. Because he's done so much for others. He's a humanitarian, just like his parents and the Helpers for Humanity."

** [[spoiler: Curly once again releases caged animals just like in “Geek Party”, only this animals belong to Lasombra, instead of a zoo.]]

** [[spoiler: A number of the scenes in the video made for the contest to go to San Lorenzo in ''The Jungle Movie'' are (remastered) scenes from the show's original run. In order, we have Arnold and Grandma cleaning Lockjaw in "Field Trip", Arnold and Gerald helping Mrs. Vitello in "Part-Time Friends", Arnold tutoring Torvald in "Tutoring Torvald", Arnold and the kids cleaning up "The Vacant Lot", Arnold getting Nadine and Rhonda to reconcile with each other in "Best Friends", Arnold going to comfort Mickey Kaline in "The Baseball", Arnold giving Eugene a bike in "Eugene's Birthday", Harold giving up Thurston the kitten in "Harold's Kitty", Arnold running off some muggers in "Mugged", Arnold dressed as a banana for the school play in "Downtown as Fruits", Arnold being crazy in "24 Hours to Live", and Arnold running with Grandpa Phil in "Steely Phil".]]

** Lila's (who is once again a silent background character) green shoes are now brown cowboy boots.

-->'''Rhonda:''' YouMonster!

* AdvertisedExtra: Although Stinky appears in the movie poster, he doesn't do anything important and has little screen time.
* AllJustADream: The movie begins with Arnold seemingly finding his parents at long last, only to reveal that it was only a dream. [[spoiler:The movie's ending makes it appear as though all the events of the movie were also just a dream, [[SubvertedTrope only to subvert it and reveal that Arnold really did find and rescue his parents.]] From the way things look, Arnold was going through the exact same routine over and over again for the rest of the summer]].

* AndTheAdventureContinues: Although the film absolutely provides a definitive resolution to the two most persistent plotlines of the series (the mystery of Arnold's missing parents and the Arnold/Helga relationship), to the point that the catchphrase among the production team was "closure happens", it still ends in such a way that the show could easily resume production without missing a beat.

* TwentyMinutesIntoThePast: The film is presumably set in the late '90s since Arnold and co. have only aged roughly around 1-2 years ahead.
* AccidentalTruth: When Rhonda asks Lasombra if he has Wi-Fi in his compound, he confirms that he does but he's not gonna tell her the password. It leads to this exchange:
-->'''Rhonda:''' YouMonster
-->'''Lasombra:''' ''({{beat}})'' How did you guess? Go change it to the other password! And don't forget to write it down this time!

** Arnold goes through a ''lot'' of trouble in this movie, including [[spoiler:learning the school trip to San Lorenzo was just to rope him in for the villain his parents warned him about to steal a precious artifact, and having nearly everyone [[{{Misblamed}} erroneously turn his back on him]].]] But he soon after [[spoiler:regains all his friends and peers, and most of all, finds his parents that for the longest time had disappeared.]]

* EveryoneCanSeeIt: Not ''everyone'', but presumably thanks to knowing them so well, Gerald has clearly figured out that Helga is in love with Arnold between the show and the movie despite her attempts to hide in, and joins Phoebe in good-naturedly teasing her about it. [[spoiler:His reaction to their first real kiss isn't so much "Whoa, you two like each other now?" and more like "It's about time".]]

* TheBigDamnKiss: At the end of the film's climax, between [[spoiler:Arnold and Helga. It's actually their ''fourth'' kiss, but it's their first mutual kiss.]]

--->'''[[spoiler:Arnold's Parents:]]''' [[spoiler:*waking up from their sleeping sickness*]] Hey Arnold...

* JerkassBall: Everyone, including Gerald and Mr. Simmons, turn their backs on Arnold who was framed for [[spoiler:getting them captured by Lasombra]] even though he had no way of knowing that [[spoiler:the video contest was a setup to lure Arnold to San Lorenzo, or that "Eduardo" was actually Lasombra in disguise]]. [[MyGodWhatHaveIDone They do eventually come around]] and forgive him, though Gerald says Arnold will be doing his chores for weeks to make up for it.

* RoleReprisal: Though many characters were recast, some of the kids and most of the adults retained their original actors. Such as:
** Creator/FrancescaMarieSmith as Helga. [[note]]This involved her coming out of retirement, as she quit acting after the show ended and is now an academic pursuing her doctorate. Fortunately, the subjects she has studied include ''fandom'' - she knows more than almost anyone how important it was that she come back to play Helga. She also stayed close with Craig Bartlett and a few of the cast members over the years, which probably helped.[[/note]]
** Anndi [=McAfee=] as Phoebe.
** Justin Shenkarow as Harold.[[note]] Notably, he's the only actor for the boys who wasn't an adult during the original who was able to reprise his role.[[/note]]
** Olivia Hack as Rhonda.
** Creator/DanielleJudovits as Big Patty.
** Creator/DannyCooksey as Stoop Kid.
** Creator/CraigBartlett as Brainy, Miles, Abner and Monkeyman.
** Antoinette Stella as Stella.
** Creator/DanCastellaneta as Grandpa Phil.
** Creator/TressMacNeille as Grandma Gertie.
** Creator/MauriceLaMarche as Big Bob.
** Creator/KathSoucie as Miriam.
** Creator/NikaFutterman as Olga.
** Dom Irrera as Ernie.
** Rick Corso as Dino Spumoni.
** Creator/CarlosAlazraqui as Eduardo.
** Dan Butler as Mr. Simmons.
** Creator/JamesBelushi as Coach Wittenberg.
** Most of the Brazilian Portuguese voice cast returned for the movie, even Marisol Ribeiro (Rhonda; who had retired from voice acting), Carlos Falat (Eugene; who was semi-retired) and Fábio Lucindo (Arnold; who had moved to Portugal).
** Only a couple actors returned in the Latin Spanish dub: Olga Hnidey (season 2) as Grandma Gertie, Claudia Motta (season 1) as Rhonda, Jorge Ornelas as Mr. Simmons, Creator/LilianaBarba as Arnold's mom, and some of temporary replacement actors.
