Mine Your Own Business is the fourth episode of the first season of Scooby-Doo, Where Are You!


The gang get lost in the desert and end up in Gold City, a spooky ghost town. They check into a deserted inn, where The owner explains that everybody has been scared off by the Miner Forty-Niner. They wind up in another mystery involving an abandoned gold mine and a ghostly, moaning miner.


Thanks to Shaggy's bad navigation (as he was holding the map upside down), the gang get lost and wind up in an old west ghost town, Gold City, on a stormy night. They check into a guest ranch whose owner, Big Ben, is delighted to see them; it seems that he's had no guests for quite a spell. When the gang wonder about this, Ben's assistant, Hank, explains that it's on account of the "Miner Forty-Niner", the ghost of an old prospector who haunts the local mine searching for the last vein of gold. Hank tells them that at night, you can hear the mine moaning, calling for the miner. He's been scaring all the guests away—and Hank himself intends to light out soon.

With nothing else to do, the gang head into Gold City to look around. Initially, they don't find anything—though in the saloon Shaggy and Scooby are startled by what seems to be a ghost playing a piano but Velma tells them that it's not a ghost and that it's only an automatic player piano. Later Shaggy is frightened by a tree branch as well as Scooby Doo thinking that the Miner has got them—until they regroup at the hotel. There, Scooby is panicked by the appearance of the Miner in a two-way mirror and knocks over a cigar-store Indian, dislodging a map of Gold City with what appears to be a safe combination scribbled in the corner. Opening the hotel safe, they find a secret elevator which takes them down into the mine itself. After Shaggy causes a mishap with dynamite (which he'd mistaken for candles). They explore the mine and find that it's lit up by lanterns, then they hear a frightful moaning echoing through the mine. The Miner appears and disappears behind some doors and chases Scooby and Shaggy in a rail car. Fred also manages to accidentally scare Shaggy and Scooby, thanks to him falling into a room full of baking flour. But the pieces start to fall together when the gang follows a wire that leads them to a room containing a tape recorder, a microphone/loudspeaker set up which is what made the moaning. They also find jars of crude oil (which Shaggy mistakenly thought was chocolate syrup). With these, they lay a trap for the Miner.

While Shaggy imitates train noises over the microphone, Scooby pilots a rail car with a loudspeaker and flashlight attached, imitating a train dashing through the mine tunnel. He chases the Miner into and through a shack (while destroying the old shack in the process). The Miner's boots fall off to reveal stilts, and he is thus unmasked as Hank. The next day, Big Ben was surprised to learn that it was Hank who was scaring off his guests to force him out of business. Hank had discovered that the mine, though exhausted of gold, is sitting on an oil well, and subsequently dressed up as the Miner to scare off everyone so he could cheaply buy and exploit the land.

Big Ben asks the gang how Hank knew about the oil. Daphne starts by saying that Hank accidentally found the secret mine elevator in the old hotel safe, Velma continues that instead of finding gold, Hank discovered the oil, and Fred explains that Hank knew the exact location layed out on a map. Shaggy finishes by saying Hank then hid the map in the cigar store Indian for safe keeping. A disappointed Big Ben comments that he and Hank could have been partners. Fred agrees, saying instead of being rich, Hank is in jail. Shaggy wonders where Scooby is.

Scooby is seen using the stilts, used by Hank when impersonating the miner, to nab some apples from a tree. Fred yells at Scooby to watch out for a gopher hole. It's too late, as Scooby steps into the gopher hole, loses his balance and falls into a water trough. Scooby ends the episode saying his name, and Shaggy concludes that one of the apples better be for him.

Full credits[]

The following credits are how they are seen on-screen (or as close as possible).


  • The episode title is a pun on "Mind your own business."
  • This episode uses different music for the title card. The music is only used again for The New Scooby-Doo Movies premiere.
  • This episode's title would be reused many years later for an episode of Scrappy & Yabba-Doo.
  • This is the first Scooby-Doo episode where Kasem and Welker take on other character roles in addition to their respective signature roles as Shaggy and Fred.
  • There's a real Indian Springs ghost town in Kern County, California, possibly placing this episode in the Mojave Desert.
  • Present-day incarnations spell "Miner Forty-Niner" as "Miner 49er."
  • Shaggy shows another of his sound imitation skills by doing vocal impressions of an incoming freight train.
  • When the Miner 49er is unmasked, Fred easily figures out it's Hank. This is because Hank's outfit matches his disguise as the Miner 49er. All that was needed was a hat and matching beard to match his hair, and small stilts inside his boots to make him look taller.
  • The classic song "Darlin' Clementine" is heard several times throughout the episode, including being played on the player piano in the saloon that the gang enter, and Shaggy and Scooby whistle it while exploring the mine tunnel. The song is sung by Huckleberry Hound all the time and was likely recycled audio clips.
  • Its not clear exactly what crime Hank would have been charged with since all he did was try to scare everyone off!


Cultural references[]

  • "Forty-Niner" was the term given to a prospector in the Californian gold rush of 1849. Many athletic teams have adopted the name as a mascot, from small-town schools to the NFL.


Animation mistakes and/or technical glitches[]

  • In the side-view of the Mystery Machine first shown riding along, Shaggy and Fred both talk, but it's just a static pose.
  • Daphne's lips are higher than they should be when she asks, "What should [they] do now?"
  • When the gang is first at the entrance of Gold City Guest Ranch about to ring the bell, Daphne's scarf is purple.
  • When Fred asks Big Ben if he has any rooms available, Daphne's eyebrows are drawn higher, underneath her bangs, making her look off-model. Her eyes were possibly drawn differently as well.
  • Velma is wearing lipstick (like Daphne's), when the girls react to first hearing the Miner Forty-Niner's name, and then when she asks Hank what the Miner Forty-Niner has to do with the ranch.
  • When Scooby gulps after hearing about the mine "calling" for the Miner Forty-Niner, the pink inside his left ear is missing.
  • When Scooby is reluctant to enter the abandoned hotel, Shaggy pushes him in, knocking the spots right off his back. Temporarily, anyway.
  • When Scooby switches with Shaggy and opens the other's closet door, the knob is on the wrong side.
  • When Daphne falls down the mine shaft, Fred looks behind him without moving his body around, resulting in his head being turned 180 degrees on his neck (which is anatomically impossible for a human).
  • When the gang hear the moan again and Daphne asks, "Do you suppose that's the miner moaning?", her pink pantyhose are missing, showing her bare legs.
  • The railroad tracks go into the tool shed in which the miner is trapped, but the door looks too close to the ground for them to fit under.
  • When Scooby pulls off the boots and falls down below, the stilts are short, but in the next few shots showing them, they're longer in length.
  • The couple of times Scooby moves to pick apples, his left foot flashes blue like the mountain behind him in the far distance.
  • When Scooby falls into the water trough, it's not the same trough shown a moment before; this one has a spigot nearby.
  • As Scooby holds up the apples while in the trough, his nose flashes brown.
  • At the saloon, when Scooby says "Two," he appears to be holding up three fingers.
  • When Scooby jumps on Shaggy after encountering the Miner, he makes a grunt without moving his mouth.
  • After Scooby uncouples the mine cart, the Miner’s eyes are just barely shown.

Inconsistencies/continuity errors and/or goofs/oddities[]

  • Shaggy is spooked by hearing that Gold City is a ghost town, even though he's holding a map of western ghost towns at the time. It’s possible he didn’t know they were all ghost towns.
  • Gold City is more like a town than a city.
  • It's easy to get the guest ranch and the abandoned hotel mixed up.
  • Shaggy enters the combination to the lock, but Fred never read the numbers off like he said. In the end it's just a plot hole to further the story along and get them to the safe since they didn't need it after all.
  • In the excitement of finding the map, Scooby never tells the gang of his encounter with the miner.
  • Shaggy opens one side of the swinging saloon door, and the other opens by itself.
  • Daphne says of the cigar store Indian, "It's hollow", although she is looking at it at such an angle that she can't see the hollow part. Similarly, Velma says, "It's a map of Gold City," while looking at the back of the map from three feet away. Perhaps it says "Map of Gold City" on the back.
  • When Fred fell through the floor, he was covered in flour. But after the rail-car chase, Freddy is cleaned off, most likely due to him brushing it off.
  • Hank used stilts to make his legs longer, but nothing was ever said about how he made his arms longer.
  • Hank was the only person who knew about the oil in the mine, so why did he wind up getting arrested? He wasn't exactly doing anything illegal, unless he was charged for trespassing in the abandoned mine.
  • The first shot of the gang talking to Big Ben at the end has the Mystery Machine behind them all, but in the second shot it is gone.

Fred: Are you sure we took the right turn, Shaggy?
Shaggy: Sure. (looks at the map he's holding) We took this road and turned to the right.
Velma: No wonder we're lost. You've been holding the map upside down.

Fred: I think we better split up and try and find out where that moan came from. I'll go this way with Daphne and Velma. You go that way with Scooby-Doo.
Shaggy: Thanks a lot.
Fred: And, Shaggy, if you find anything, holler.
Shaggy: I'm liable to holler even if I don't find anything.

Shaggy: Look! Stilts!
Velma: Shaggy's right. He is wearing stilts.
Fred: Then this can only be only one person. (Fred removes the Miner Forty-Niner's long beard, knocking off his hat in the process, to reveal Hank) Hank!
Daphne and Velma: Hank?!
Hank: Aw, dagnabbit!
