"VELMA:" "Are you sure this is the road to the U.S. border, Fred?" "No, I'm not. I think we're lost." "Lost?" "On a creepy night like this in the middle of nowhere?" "Relax, you two." "There's nothing to worry about." "We'll find the main road soon." "Hey!" "Look up ahead." "DAPHNE:" "It's a roadblock." "Jeepers!" "What's going on?" "MAN:" "Hold it right there." "Stay in your vehicle." "Like, who are you?" "I'm Officer Oldfield of the Royal Canadian border patrol." "OLDFlELD:" "What are you doing on this road?" "We're, like, tourists, aren't we, Scoob?" "Uh-huh, tourists." "See?" "This side road is a favorite of lawbreakers trying to sneak across the border." "VELMA:" "Our only crime is that we're lost." "You kids can proceed but be sure to take the left fork ahead." "Foster Road, it'll take you to the main highway." "Okay, officer, and thanks." "Remember, don't take the right fork." "There have been lots of weird things happening on that road." "Weird things?" "OLDFlELD:" "Like the ghost of Dr. Coffin who went mad, coming back to haunt the whole area." "Ghost?" "Ghosts are bad enough, but mad ghosts are the worst." "Yeah." "Thanks for the warning." "FRED:" "Keep an eye out for that sign, gang." "VELMA:" "Right." "[THUNDER rumbling]" "DAPHNE:" "There it is, "Foster Road."" "VELMA:" "We've been driving for an hour." "I hate to say it, but I think we're lost again." "Zoinks!" "I hope we didn't take that road he warned us about." "Yeah." "[siren wailing]" "Hey, an ambulance." "Let's follow him." "He must know his way around here." "FRED:" "Good idea." "Looks like we followed him right into a driveway." "And this place is some kind of sanitarium." "SHAGG Y:" "It sure looks creepy." "VELMA:" "Maybe we could stay here for the night." "Uh-uh!" "Uh-uh!" "Look at those ambulance men." "What are they doing?" "FRED:" "They're bringing in a new patient." "VELMA:" "In this weather?" "And this time of night?" "Yikes!" "[WHlMPERlNG]" "What's the matter, Scoob?" "A ghost!" "A ghost?" "SHAGG Y:" "I don't see anything." "A doctor?" "A mad doctor?" "A mad doctor!" "Zoinks!" "The ghost they warned us about!" "Will you two relax?" "Come on, everybody, the rain's letting up." "FRED:" "Let's go inside." "[ORGAN music playing]" "Zoinks!" "Like, what's that?" "Just somebody playing the organ." "Well, he sure ain't Stevie Wonder." "[growling]" "VELMA:" "Look out!" "DAPHNE:" "Guard dogs." "SHAGG Y:" "And they're after us." "Hey!" "Watch it!" "Take it easy." "SHAGG Y:" "Careful, Scooby." "Watch those jaws!" "[ORGAN music STOPS]" "How do you like that?" "They just wandered off like friendly little puppies." "Uh-huh." "Puppies." "[giggling]" "Come on, you two. lt's safe now." "Yes?" "Excuse me, sir, but we got lost in the storm and-- l'm Dr. Tewksbury." "Come in, come in." "Look!" "Oh, yes." "TEWKSBURY:" "Cuddles and Snookums." "Cuddles and Snookums?" "TEWKSBURY:" "They were pets of the late Dr. Coffin who was the original owner of the sanitarium." "I was his assistant." "I thought those snarling hounds were gonna eat us alive." "Yeah, and then they just wandered off like puppies." "I can explain that." "[growling]" "TEWKSBURY:" "Dr. Coffin was using them in his brain-wave experiments." "He could control them by playing various kinds of music on the organ." "Say we heard an organ just before those dogs jumped us." "Yes." "I'm very much afraid that what you heard was the ghost of Dr. Coffin." "Ghost?" "I knew it." "That's the ghost the trooper warned us about." "That does it!" "Nice to meet you, Dr. Gooseberry." "And, like, goodbye." "Goodbye." "Just a moment." "TEWKSBURY:" "Won't you stay for dinner?" "Dinner?" "Dinner?" "Thanks." "We'll be glad to." "VELMA:" "We'd better join those two before there's nothing left but toothpicks." "Would you pass everything, please?" "What are you doing, Scoob?" "Making shish kebab." "Oh." "Forgive my curiosity, doctor but how come we haven't seen any patients around this place?" "I don't understand it myself." "They keep bringing me patients, but they vanish." "TEWKSBURY:" "Most of them were scared off by the ghost of Dr. Coffin." "Uh-oh." "TEWKSBURY:" "At first I paid no attention to the ghost stories but then several of my patients suddenly disappeared." "Disappeared?" "It's said he's returned from the grave to finish his brain-wave experiments, and to do that he needs people to experiment on." "Jeepers!" "Maybe he'll want us!" "Not me, because, like, I won't be here." "TEWKSBURY:" "No, no, my boy." "It's much too stormy out to travel." "Do be my guests and stay for the night." "Of course we'll stay." "And thank you." "[THUNDER rumbling] I'll sleep here." "Shaggy, you take that bunk and Scooby, you can sleep by the window." "Okay." "[CACKLlNG]" "FRED:" "Dr. Coffin's ghost." "SHAGG Y:" "Zoinks!" "He's gone." "I just wish that mad doctor wouldn't make house calls." "Come on down, Scooby." "It's safe now." "Whew." "Look!" "That moose head opened a secret passageway." "FRED:" "Let's see where it goes." "You go." "We'll, like, stay here and guard the girls." "Yeah." "Quit stalling and start moving." "Sheesh." "Come on, you two." "Ghost!" "Zoinks!" "A ghost!" "Take it easy, Shag." "That's no ghost." "It's just a huge mirror." "Oh." "[giggling]" "[growling]" "[giggling]" "FRED:" "Scooby, this is no time to clown around." "We've got to find a light switch." "Here's a switch." "Look at that." "You just opened the roof." "SHAGG Y:" "Yeah." "Like, that's really weird." "And look, there's the moon." "Ow!" "[sighing]" "Like, what's happening?" "What's going on here?" "That huge mirror concentrated the moonlight and made a beam hot enough to sizzle Scooby's fur." "Yeah." "SHAGG Y:" "But who'd be crazy enough to build a room for hot moonbeams?" "The doctor's ghost?" "Like, sorry I asked." "FRED:" "Now I get it." "This isn't for moonbeams, it's for sunbeams." "And this is a solar furnace." "Oh." "What's a solar furnace?" "It's used to create high temperatures by concentrating rays of sunshine." "But, like, what's one of those things doing in a creepy sanitarium?" "I don't know." "Yet." "[CACKLlNG]" "Zoinks!" "The mad doctor." "Yikes!" "SHAGG Y:" "Like, clear the track." "[WHEELS rolling]" "Daphne, get up." "Come here." "What's happening?" "VELMA:" "They're loading people into that ambulance." "DAPHNE:" "At this time of night?" "VELMA:" "Yes." "But those patients don't look alive anymore." "You mean they're" "FRED:" "Velma!" "Daphne!" "Open up!" "What's the matter?" "Like, the mad doctor is running loose!" "Yeah." "And we found a secret passageway to a weird room." "That's not all that's weird." "Take a look at that ambulance." "FRED:" "Where could they be going?" "VELMA:" "By the looks of those patients, I'd say the cemetery." "[lN unison] Cemetery?" "We'd better follow them." "[THUNDER rumbling]" "DAPHNE:" "What's that funny rumbling sound?" "It must be Niagara Falls." "We're pretty close." "Uh-oh!" "Look!" "SHAGG Y:" "It says, "Warning, bridge out ahead."" "We'd better turn back." "Turn back." "Not a chance." "If the ambulance can make it, we can make it." "DAPHNE:" "Fred, look out!" "Wow!" "Like, we almost went over the side." "But where's the ambulance?" "It just disappeared." "Shaggy, look." "[CACKLlNG]" "Zoinks!" "The mad doctor!" "DAPHNE:" "Now he's gone." "Wow." "Vanishing doctors, vanishing ambulances." "This is really getting mysterious." "Let's get back to the sanitarium." "Maybe we can solve this mystery in the morning." "[THUNDER rumbling]" "[snoring]" "[ORGAN playing]" "Zoinks!" "He's gone." "Hey, what's the matter?" "The ghost!" "The ghost got Scooby." "Come on, let's get the girls." "Scooby's disappeared." "And listen." "There's more of that weird music coming from downstairs." "We'd better find out what's going on." "Wow." "Do you see what I see?" "It's Scooby and that mad doctor." "VELMA:" "Scooby acts like he's under a spell." "FRED:" "He is. lt's that weird music." "Scooby." "Like, wake up." "SHAGG Y:" "Wake up, Scoob, and run for it!" "Yikes!" "[growling]" "Uh-oh!" "The dogs are coming after us." "Like, head for the hills." "[barking]" "We're safe, Scoob." "Zoink!" "A" " A monster!" "Scooby-Dooby-Doo!" "Oh, Scoob, you know you scared the life out of me?" "[giggling]" "VELMA:" "Quick." "We'll hide in here." "[growling]" "We ditched them." "Oh, excuse me, madam." "[giggling]" "Why, it's Scooby." "VELMA:" "And Shaggy." "And a pile of wigs." "DAPHNE:" "Wigs?" "What use could a sanitarium have for all those wigs?" "Maybe they belong to the mad doctor's ghost." "SHAGG Y:" "Like, he sure has flipped his wig." "I've got a feeling this will all fit together sooner or later." "Come on, let's split up and look for more clues." "[THUNDER rumbling]" "Shh." "SHAGG Y:" "Yikes!" "Shh." "Like, this must've been the old doctor's lab when he was alive." "Look, Scoob." "SHAGG Y:" "He must have used that for his experiments with music." "And I'll bet I know just how he did it, Scoob." "Have a seat." "Okay." "Like, the patients sat right here and the doctor would start the old phonograph and" "Aah!" "[CACKLlNG]" "Zoinks!" "Like, he wants to use us!" "SHAGG Y:" "Aah!" "[CACKLlNG]" "Aha!" "SHAGG Y:" "Take off, Scoob." "GHOST:" "Aah!" "Shaggy, I'll save you." "Yikes!" "SHAGG Y:" "Yeow!" "SCOOBY:" "Hey!" "Say, "Ah."" "Aah." "You ought to see a doctor." "Aah!" "SHAGG Y:" "Yikes!" "Aha!" "SHAGG Y:" "Yeow!" "SCOOBY:" "Help!" "SHAGG Y:" "Run, Scooby!" "[GHOST CACKLlNG]" "[yelling lNDlSTlNCTLY]" "Good work, Scoob." "You got him!" "Let's check in here." "Oh, no!" "It's a morgue." "DAPHNE:" "All those patients that disappeared they're dead." "It's not what you think, Daphne." "Look!" "Stacks of gold bullion." "VELMA:" "With a wig to make us think it was a person." "Well, that explains all those wigs we found." "FRED:" "This gold ties in with that cauldron we found in that weird solar-furnace room." "Are you thinking what I'm thinking?" "FRED:" "You bet I am, Velma." "This whole mystery is starting to make sense." "Uh-oh." "Somebody's coming." "We'll hide back there." "Come on." "Zoinks!" "A morgue!" "A-- A morgue?" "MAN:" "Hurry." "We must deliver another body." "Quiet, Scoob." "Like, they're coming in here." "Ah." "These will do." "DAPHNE:" "Creepers, they're taking Shaggy and Scooby." "FRED:" "Come on, after them." "Where are we going?" "Like, I don't know." "Keep out of sight." "[TEETH chattering]" "VELMA:" "They're headed down the same road toward the falls." "This time we'll follow so closely they can't disappear." "What if they spot us?" "That's a chance we'll have to take if we ever want to see Shaggy and Scooby again." "Don't worry." "They won't spot us with our headlights out." "[siren wailing]" "Jeepers." "So that's where they went." "And that's where we're going." "VELMA:" "Wow." "That was close." "DAPHNE:" "It's a secret road through the mountain." "And it sounds like it passes right behind the falls from the Canadian side to the United States." "It's certainly all adding up." "Psst." "Scooby." "Go see who's up front." "Mad doctor?" "Yeah." "FRED:" "We'll stop here and sneak up on them." "There's the ambulance, and they're unloading Shaggy and Scooby." "Jeepers." "Look at that." "VELMA:" "Stacks and stacks of gold bullion." "FRED:" "And what looks like a bread-wrapping machine is used to disguise the gold." "Come on." "Somehow we've got to rescue Shaggy and Scooby." "[GULPS]" "Who's this?" "A dog." "Excuse me." "MAN:" "Catch him!" "Don't let him get away!" "They found Scooby." "SHAGG Y:" "Zoinks!" "What's happening?" "Look out." "SHAGG Y:" "Like, help!" "After them!" "[laughing NERVOUSLY]" "Zoinks!" "That mad doctor's ghost and those ambulance guys are after us." "And they're getting closer, Scoob." "Oh, we're goners." "We're stopping." "Uh-oh." "SHAGG Y:" "We're gonna crash!" "Back, you fools!" "Back!" "Here they come." "Now we'll find out who the mad doctor really is." "Well, there's only one person it could be:" "Dr. Tewksbury." "[gasping]" "FRED:" "Officer Oldfield!" "MAN:" "The man posing as Officer Oldfield is actually the ringleader of a multi-million-dollar gold robbery that occurred in Montreal a month ago." "And, like, he played ghost and used those dogs to scare people away from the sanitarium." "MAN:" "Hmm." "VELMA:" "To get the gold as far as the border, the smugglers cast it into human-shaped figures wearing those wigs we found." "FRED:" "Then they shipped the figures by ambulance so the authorities would think they were patients and let the ambulance go through." "MAN:" "Very clever." "DAPHNE:" "Then they brought the gold figures to the sanitarium and melted them down into gold bars with that solar furnace you found." "FRED:" "And finally, they'd bring the gold bars to the cave disguise them in bread wrappers and take them across the border into the U.S.A." "But what about Dr. Gooseberry?" "Tewksbury." "He had nothing to do with it." "TEWKSBURY:" "Quiet down there!" "A man's trying to get some sleep." "Like, how do you like that?" "He slept through the whole thing!" "[laughing]" "One thing this mystery taught us like, Scooby's a real Fred Astaire." "Scooby, you're a marvelous dancer." "[giggling]" "Yikes!" "And, like, Scoob's a great runner too."
