Scooby-Doo! and the Monster of Mexico is a 2003 direct-to-video animated comedy mystery film; the sixth in a series of direct-to-video films based upon the Scooby-Doo Saturday morning cartoons. It was released on September 30, 2003, and it was produced by Warner Bros. Animation.

It is the second and final film (after Scooby-Doo and the Legend of the Vampire) to briefly reunite the surviving original voice cast from the original 1969 series, with Frank Welker voicing Scooby-Doo in place of the late Don Messick.


Fred's pen-pal, Alejo Otero, a man who lives in Veracruz, Mexico, invites Fred and the rest of the gang to visit him and his family there. Fred and the rest of the gang talk about it until they decide to go. However, after Alejo sent the invitation to Fred, a big long-haired monster started to terrorize the population of Veracruz. Alejo and his young son, Jorge, and their pet Chihuahua, Chiquita, see the monster, and the locals start calling him "El Chupacabra".

Later, when Mystery, Inc. arrives in Veracruz, they meet Alejo, who recognizes them all from Fred's letters, though is confused as to how Shaggy's description is a fair representation of his eating habits. Alejo and his family run a huge and fancy hotel, and he shows them around and where they will be staying. He then introduces to them his family, which includes his wife, Sofia, his mother, Doña Dolores, his brother Luis, and Luis's fiancée, Charlene, who is originally from the United States. Luis tells the gang he met Charlene when he visited America, at a theme park run by Mr. Smiley. The gang and the Otero family enjoy a meal, and Dolores talks about her late husband. Then, a man named Señor Fuente arrives and asks to speak with Alejo and Luis. Dolores tells the gang that Fuente has been trying to get her to sell the hotel to him ever since her husband died the previous year. Meanwhile, Alejo and Luis tell Fuente once again that they do not want to sell the hotel. Fuente leaves, and the family go inside because of a fierce storm. When inside, Alejo's forced to tell the gang about El Chupacabra. He says that he does not have many other guests besides the gang because El Chupacabra has been scaring them away. Luis and Charlene tell the gang to lock their doors when they go to sleep.

During the night, Shaggy and Scooby-Doo are scared when they think they hear a noise. They then hear a loud growl and run screaming out of their cottage. After seeing footprints outside of Shaggy and Scooby's window, Fred declares that there is a mystery they have to solve. The next day, the gang and the Otero brothers set out to search for El Chupacabra. Charlene gives Luis a charm for good luck. Daphne interviews the townspeople, but none of them are able to find El Chupacabra. When they get back to the Mystery Machine, they find someone has written a threat written in Spanish on it, warning them to get out of solving the mystery. The gang realizes this is serious and decide to search at night. Fred, Velma and Daphne go one way, Alejo and Luis go another way, and Shaggy and Scooby stay at the Mystery Machine.

At night, Shaggy and Scooby sleep in the van, while someone drains their brake fluid. Fred, Velma and Daphne search the woods, and find El Curandero, a medicine man. El Curandero tells them they need to look at history and that they are in grave danger. Meanwhile, Alejo and Luis are searching when Alejo sees El Chupacabra. Alejo is chased and nearly falls off a cliff. He calls for Luis, but there is no answer. El Chupacabra disappears, and Luis shows up, saying he was knocked on the head by El Chupacabra. Luis helps his brother up from the cliff.

Shaggy and Scooby start driving, but then realize they cannot stop due to the brake fluid tank being tampered with. They meet up with Fred, Velma, Daphne, Alejo and Luis, who were being chased by El Chupacabra. Eventually, the van runs out of gas and stops right in front of a gas station. The Mystery Machine gets fixed, and Daphne gets some ice for Luis's head wound, but Luis does not have a bump on his head. The gang drives along and finds a sign to a history museum, and thinking that is what the medicine man said, go to it. When they get there, they meet a suspicious and hyper museum guide who leads them into an auditorium. There they see a performance about ancient Mexican customs. The guide then makes Daphne volunteer, and she kidnaps her. The rest of the gang find a secret passageway and follow it, until they come to Aztec pyramids. They find Daphne at the top of one and rescue her, but the tourists chase after them, after they are accused of destroying a statue. After a long chase scene and fights against giant living statues, they finally return to Veracruz.

The next day is the Day of the Dead, and all go to the cemetery, where Dolores informs them that Charlene has been captured by El Chupacabra. The family gives offerings to the grave of Señor Otero and hope Charlene can be found. Suddenly, the ghost of Señor Otero comes out of his grave and tells them to sell the hotel and the land or they will be in danger. At the same time, Fred just revealed the good luck charm Luis has is really a tracking device instead of an ancient medallion. The family cannot believe that Señor Otero would want them to sell. Scooby and Chiquita follows a beeping noise that is activated by pushing the button from the tracking device until they find a man in a skeleton suit controlling the ghost. The gang catches him, and he is revealed to be Mr. Smiley. They deduce that he started the Chupacabra scheme so he could force the locals to sell their land and allow him to build his theme park. Him kidnapping Daphne and framing the gang as vandals was his way of creating bad publicity for the pyramids, his sole competitor for the thousands of tourist dollars. As they are about to close the mystery, El Chupacabra appears and scares everyone.

After chasing the gang, El Chupacabra is caught up in some wiring. As they all gather around El Chupacabra, the culprit is revealed to be the museum guide when she climbs out of the suit. She tells them she loves Mr. Smiley and that they were going to get all the land. Luis asks what happened to Charlene, and the guide tells him he will never see her again and he should forget about her. Suddenly, the Oteros reveal that the offerings they left for Señor Otero have disappeared, all except for the one from Charlene. Velma then guesses something is up and realizes the guide is wearing a wig and glasses to hide their identity, and pulls it off to reveal that Charlene was the guide and El Chupacabra. Her true identity is given away by the random tossing of coffee beans, a trait Charlene adopted from working in the hotel cafe all day. Charlene revealed that she, knowing Smiley's Chupacabra scam wouldn't scare them off, intended to scam the Oteros out of their land once she married Luis. Fred realized they were behind it when he notice that the message written on the Mystery Machine ("Sal ahora o no veras el dia de manana!" - Leave today or you won't see tomorrow!) was not written in proper Spanish (as the word "manana" should have been "mañana"), so whoever made the threat had to have been someone who could not understand the language.

Señor Fuente then comes in and says that even though he wanted to buy the Otero family's land, he eventually came to respect the fact that they did not want to sell it. Fuente explains that he learned of Mr. Smiley and Charlene's plans and wanted to warn the Oteros and Mystery Inc. of what was really going on. Luis admits that the real reason he did not come to Alejo's rescue because he was paralyzed with fear — after their father died the previous year, Luis was afraid of losing Alejo, so he lied by saying that El Chupacabra had knocked him unconscious. Alejo comforts Luis and assures him that there are worse things than being a coward, to which Shaggy adds how he has "made a career out of it." In the end, everybody enjoys the Day of the Dead festivities.

  • Instead of the correct reptilian (or canid) monster, a purple Bigfoot was used for the Chupacabra.
  • During one of the chase scenes, the gang stops at a movie theater. A movie titled, Legend of the Vampire is seen in the marquee. This is a reference to the previous film, Scooby-Doo! and the Legend of the Vampire.
  • This is the last time Heather North and Nicole Jaffe voice Daphne and Velma respectively, before North's death in 2017, with their successors being Grey DeLisle and Mindy Cohn, respectively. DeLisle debuted as Daphne in the fourth DTV film Scooby-Doo and the Cyber Chase. Cohn and DeLisle were also already voicing their roles in the TV series What's New, Scooby-Doo?
  • Fred reveals to Alejo that the reason why Shaggy eats so much and doesn't gain any weight is because he has a high metabolism.

Cultural references

  • The Chupacabra's roaring sounds are the same stock roars originally recorded for Hanna-Barbera's Godzilla animated series from 1978–1979, as performed by Ted Cassidy.
  • One of the lyrics in the "Viva Mexico" song is "Let me hear you scream '¡Ándale! ¡Ándale!'", which was a common exclamation from another Warner Bros. Animation character, Speedy Gonzales.
  • At the beginning of the Day of the Dead ceremony, a child is wearing a Yogi Bear mask.
  • Scrappy-Doo, Fred Flintstone and Yogi Bear made cameos in the bloopers.
  • There are a couple of references to the film The Wizard of Oz:
    • Velma, Fred, and Daphne mention "Coyotes, jaguars and boars, oh my", which is a reference to the line "Lions, and tigers and bears, oh my".
    • Mr. Smiley's line, "Pay no attention to the man behind the curtain" is a paraphrase from the Wizard of Oz's line "Pay no attention to that man behind the curtain".


  • Scholastic published a novelization using the same name on October 1, 2003. It was written by Jesse Leon McCann.
  • This movie inspired the tenth level of the game app Scooby-Doo! Mystery Cases, which is called The Legend of El Chupacabra.

Animation mistakes and/or technical glitches

  • When Doña Dolores was talking about Diego Fuente, her skirt and Velma's were switched to each other.
  • When Chiquita was giggling at Scooby for walking into a gravestone, and laughing at the Chupacabra tripping over a pumpkin, her eyes were colored black instead of brown.
  • When the Ghost of Señor Otero appeared, Sofia's right wrist band is missing.
  • When Alejo tried to wake up Doña Dolores when she fainted, and Alejo comforting Luis, his wristwatch on his left arm is missing
  • When Fred shows the gang how a tilde is used in the Spanish word for "tomorrow," he writes the symbol over the wrong n, spelling the word as "manaña" instead of "mañana."

Inconsistencies/continuity errors and/or goofs/oddities

  • The homes the gang live in could be set in Coolsville, but that's not outright confirmed.
  • While in split-screen, the gang go from speaking out loud to themselves then to typing, and finally to just speaking without typing and somehow everybody seemingly knows what each other is saying. The four-way split-screen could be breaking the "fourth wall" for them.
  • It's unexplained how Fred, a teen, got in contact with Alejo, a family man, with a business.
  • Only Jorge is supposed to be Alejo and Sofia's kid, but Carolina, Sebastian, and Natalia are given the Otero name in the credits.
  • El Chupacabra is claimed by to be Mexico's version of Bigfoot, although such a description is grossly inaccurate, as the Chupacabra described is quite different from Bigfoot. There's two popular depictions of the creature:
    1. Is a strange reptilian beast with big red eyes and sharp teeth.
    2. A strange rabid wolf or dog like creature with gray fur.
  • This movie portrays the Chupacabra as a Mexican legend in origin; however this is not accurate since the Chupacabra has its origins in Puerto Rico. It should be noted, however, that most of these mistakes were made by the ignorant American villains. They chose how their monster costume would look. Although the villagers had noticed the discrepancy.
  • Velma incorrectly states that Teotihuacan (the pyramid complex where the gang emerges after following a secret passage from the Museum of Anthropology) was built by the Olmec civilization. Teotihuacan is thought to have been established around 200 BCE, in the highlands of Central Mexico, near Mexico City. The Olmec civilization flourished from 1500 BCE to 400 BCE in the Gulf Lowlands to the east and south.
  • During the scenes of Paco framing the Mystery Inc and Alejo and Luis just before the tourists started chasing them on top of the Aztec pyramid, Alejo's clothes suddenly changed into the same colors as Luis's. Also, the angry tourists keep swapping positions.
  • When Charlene is unmasked as the museum guide, only her wig and glasses are removed, even though she clearly wears a mask while disguised as the museum guide.
