About Scooby-Doo and the Monster of Mexico
Fred's pen-pal Alejo Otero, 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 monster started to terrorize the population of Veracruz. Both Alejo and his son see the monster, and the locals start calling it El Chupacabra which is hispanic for goat sucker.
Later, when Mystery, Inc. arrives in Veracruz, they meet Alejo who recognizes them all from Fred's letters. Alejo runs a huge and fancy hotel, and he shows them around and where they will be staying. He then shows them his family which include his wife Sofia, his mother Doña Dolores, his brother Luis, and Luis's fiancée, Charlene. Luis tells the gang he met Charlene when he visited America, at a theme park run by Mr. Smiley. The gang and the family enjoy a meal, and Dolores talks about her late husband. Then, a man named Señor Fuente arrives and asks to speak with Jorge 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. 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 is forced to tell the gang about the monster. 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.
