Scooby-Doo Meets the Boo Brothers is a 1987 animated made-for-television film produced by Hanna-Barbera as part of the Hanna-Barbera Superstars 10 series. The two-hour film aired in syndication. Plot Shaggy discovers that his uncle Colonel Beauregard has died and left him his country estate, which is on a Southern plantation. After being chased away by a ghost witch, Shaggy, Scooby and Scrappy head for the estate in order to claim Shaggy's inheritance. Before they can get there, they meet Sheriff Rufus Buzby, who warns them about the whole estate being haunted and that they should leave. Before he can fully convince them, he receives a call from dispatch, notifying him that a circus train has derailed and a circus ape has escaped. Leaving Shaggy, Scooby and Scrappy, they continue driving, but upon their arrival they are pursued by a headless horseman, a ghost wolf, and by the alleged ghost of the Colonel who taunts them, telling them to leave or else they will face the consequences. They also meet the creepy manservant Farquard who tells them that a vast fortune in jewels is hidden somewhere on the estate, which he believes is rightfully his and that Shaggy has no business there. Initially, Shaggy wants to leave, but before they can do that, his truck sinks into quicksand, forcing him, Scooby and Scrappy to spend the night there. With ghosts haunting the place, Scrappy has the idea to call a group of ghost exterminators called The Boo Brothers. Surprisingly, the exterminators—Meako, Freako, and Shreako—are themselves ghosts styled after The Three Stooges, who proceed to hunt down the ghosts that are haunting the estate, with little success. On top of all, Shaggy meets Sadie Mae Scroggins and her shotgun totting older brother Billy Bob Scroggins whose family has an old feud with the colonel. After knowing that Shaggy is related to the colonel, Sadie falls in love with him and Billy Bob wants to shoot him. After things calm down a little, Shaggy, Scooby and Scrappy decide to go to the kitchen to eat something, only to find proof that the famous fortune in jewels is real, when they find a diamond with a clue to a treasure hunt. Intrigued by that very first clue, the gang decides to hunt down the rest of the jewels much to Farquard's chagrin and Sheriff Buzby, who is on the trail of an escaped circus
