History WesternAnimation / ScoobyDooAndTheMonsterOfMexico

* BlazingInfernoHellfireSauce: During the "Viva Mexico" portion of the film, Scooby eats some chili peppers which are too spicy for even him to handle and goes searching for some water, even [[FireBreathingDiner breathing fire in the process]].

** So how many of the things at the pyramids were special effects? It is strongly implied that not all of them, since the animatronic eagle Paco (which is operated by the main villain) was visibly afraid of the living statues, and was attacked by the two jaguars that came to life.

* MyHovercraftIsFullOfEels: Fred's Spanish speaking leaves something to be desired, though he usually gets most words right. Unfortunately, the few he gets wrong are enough to turn the sentence into gibberish (e.g., "Thank you for your wise words of ostrich."). [[spoiler:Ironically, he's much more versed in Spanish ''grammar'', as he manages to figure out a major clue from a threat written in Spanish containing an error a native wouldn't have made.]]
* NightmareFetishist: The tour Guide, smiling widely, talks about how the ancient Aztecs' sacrifices involved "ripping out their still-beating hearts to offer to the Gods. Super!"

* WrongGenreSavvy: The tourists ''think'' they’re in some lighter movie with actual spirit animals and being {{BadassBystander}}s against the sinister vandals but are really just {{Unwitting Pawn}}s of the villains who've been distracted into chasing the heroes.

* BitchInSheepsClothing: The museum guide, also known as [[spoiler: Charlene]], is a much crueler person than she seems.

* [[DatingWhatDaddyHates Dating What Mommy Hates]]: [[spoiler: After Charlene's revealed as one of the culprits and is carted off to prison alongside her lover, Mr. Smiley, Dolores (Luis and Alejo's mother) reveals that she never liked Charlene that much to begin with, even going so far as to call her a "bruja" (which, as Fred notes, is [[WitchWithACapitalB the Spanish word for "witch"]]).]]

* {{Foreshadowing}}: Luis mentions that he met Charlene at Mr. Smiley's Funland amusement park. [[spoiler: It turns out that she is romantically involved with Mr. Smiley.]]
* GenreSavvy: El Curandero tells the gang that they will be in grave danger if they continue investigating, and [[spoiler: predicts the culprits are businessmen from up north who had their development plans refused by the locals]]. He's dead right on both points.
* GoldDigger: [[spoiler: Charlene (very openly) admits that she only loved Luis for his family's wealth.]]

* KickTheDog: [[spoiler: An annoyed Charlene chews out Luis for being a hopeless romantic and reveals that she only wanted his money and that she and Mr. Smiley are a couple. Telling him, "Oh, would you wake up and smell the café lechera, you pea-brained romantic?"]]
* LanguageBarrier: [[spoiler: The threat written in Spanish on the Mystery Machine had a grammar error no real Spanish-speaking person would make, and the alleged ghost of the Otero patriarch only spoke English. These are hints that the bad guys don't speak Spanish.]]

* RedHerring: Señor Fuente. He is introduced wanting to buy Alejo's land, despite previous refusals. Doña Dolores says she never trusted him and calls him a jerk... but he isn't the bad guy. In the end, he explains that, for as much as he wanted to buy the Ortero's land, he came to respect the fact that they didn't want to sell it and admired the family's love for his old business partner, Señor Otero (Luis and Alejo's dad).[[spoiler: He also explains that he had learned of Charlene and Mr. Smiley's scheme and wanted to warn them of it.]]

** [[spoiler: When he heard Alejo yelling for help, Luis freezes in terror rather than immediately running over (since their father's passing, he was afraid of losing his brother too), and initially claiming he'd been unconscious at the time something he clearly sees as his MomentOfWeakness and is ashamed of it. He apologizes for his cowardice, but Alejo immediately forgives him, claiming that there are worse things than being a coward. Shaggy, a self-proclaimed coward, would know.]]
** The gang publicly apologize to [[spoiler: Luis]] for wrongfully suspecting him even though he'd had no knowledge of that mistaken suspicion and wouldn't have ever known if not for their apology.
** [[spoiler:Señor Fuente, upon getting an inkling of Smiley's scheme, chooses to warn the Ortero's rather than just sit back and try to profit off of it himself]].
* WrongGenreSavvy: The tourists ''think'' they’re in some lighter movie with actual spirit animals and being BadassBystander's against the sinister vandals but are really just {{Unwitting Pawn}}s of the villains who've been distracted into chasing the heroes.

* DamselInDistress: Daphne gets kidnapped in a tourist attraction mid-film in an attempt to scare away the gang, but she is found outside shortly after.
