Write really overly-funny super hilarious comedy 17+ short Scooby-Doo cartoon parody transcript that always starts with the opening FROM THE FIRST PARAGRAPH SENTENCE moment first, then the gang hearing about it once they reach the area, and then the rest based on my prompt: (but make it more funnier adult comedy where the gang constantly make fun of and question physics that ain’t possible or don’t make any sense and why, Velma is too smart…Scrappy is overly-heroic and thinks he’s a superhero, which they're actually happy with, and appears alot, Shaggy, ALWAYS confused, mocks EVERY SINGLE name of people INCLUDING THE VILLAINS NAMES AFTER THAT with Scooby also mocking them, Fred will always mistake a character for a famous person because of their surname being literally the same as a real life celebrity (Ironically they would have a parody name that sounds like the celeb but punny), forcing the character to correct them angrily, Fred would also put the blame for a monster’s crime on Red Herring (From A Pup Named Scooby-Doo), who’d often get mad at Fred for still blaming him and ends up in a funny situation himself before disappearing offscreen. The gang always know that a place they are going to doesn’t sound like it exists, they also know something in a place they go to shouldn’t even be there as it makes no sense, they question names of things or people and why, and even question the motives and why (Plus they constantly do pop culture references and jokes, and mentions of famous people, games, songs, and shows occasionally, AND they’d make fun of the plot in the prompt: THE GANG ALWAYS MOCKS ThE NAMES OF EVERYONE THEY MEET. EVEN THE VILLAINS AND EVEN MOCK THE LOCATION NAMES TOO. (Do this with EVERY prompt i give. Add the title too) 

Shaggy, and Scooby, have just watched "Return of Astro Mutt: Space Dog of the Future" at the theatre, twice, and are strolling down a street when their van, the Mystery Machine, suddenly comes to life. At first they think it's Fred giving them a lift, but they quickly realize that nobody is driving. The van turns around and plays a spooky music riff, prompting the duo to run for their lives.

The rest of the gang are having drinks when Shaggy and Scooby burst in hysterically, claiming that the Mystery Machine is chasing after them. The gang go and investigate, only to find that the van isn't moving, and is still in the same spot. However, while Fred is driving, the van suddenly takes over, and they head straight towards a road barrier. They would've crashed had Scooby not released an installed parachute, which slowed them down enough to avoid colliding with the barrier.

They go to see Murph, a mechanic, who seems keen on buying the van for a reasonable price. The gang refuse. Abruptly, and without notice, the van pulls out of the garage and drives away, with oil leaking onto the road. The gang follow this trail of oil and it leads them to a house. They knock on the door and a woman answers. She turns out to be the mother of the Mystery Kids, Andy and Mandy Dinwiddie, the previous owner of the Mystery Machine. She seems keen on reviving the group, but the kids don't seem so enthusiastic. Andy's trying out for the tennis team and Mandy is picking out her prom dress but Susan won't allow it. The gang are told by the Kids and their mother about Flash Flannigan, their late pianist who stormed off stage during a performance. They say he went to 'Rock and Roll Heaven'. When leaving, the gang bump into a brother of Andy and Mandy that Susan didn't mention. He says that he's working on a science project.

The gang head into the city center, but they are followed by the Mystery Machine, which attacks them, glowing eerie green lights and playing spooky music riffs. Luckily, the gang manage to escape. They find a cab and head towards the university where Randy is working to get answers. He explains that he's working with animatronic mechanisms, that allow him to control anything wirelessly. Even though his Mom helps him with his homework, she doesn't seem interested in his work.

Seeing that Murph seems the only person capable of helping them, they go back to the garage and find a 'private' back room, which happens to be filled with Mystery Kids merchandise and videos. When putting one of the films on, it talks about how Flash Flannigan disappeared and how a flower appears on his gravestone. The gang decide to investigate the cemetery and use some bikes, scooters, skateboards and roller skates as means of transportation until they get the van back.

When there, they see Andy and Mandy kneeling next to the grave of their friend. Fred suspects something. The Mystery Machine suddenly arrives and starts chasing the gang, until it finally nets Shaggy with the doors. On their scooters, the gang chase the van down the wrong side of the motorway. The Mystery Machine stops and a policeman gives Shaggy and Fred a warning for the trouble caused.

While the Mystery Machine is kept in custody with the police, the gang head to see the Mystery Kids prepare for their show. Murph happens to be there. Velma decides to hold a séance and Daphne improvises by pretending to call to Flash in the spirit world. The Mystery Machine coincidentally arrives, to Daphne's surprise. Velma has a plan ready though, and drops a lead-lined cover over the van, meaning that wireless control doesn't work. When they pull back the table cloth, the culprit turns out to be Susan Dinwiddie, who had been controlling the machine using a wireless control, which she learned while helping Randy with his homework. When the Mystery Machine was getting tuned up, she rigged it with a video camera and controller allowing her to control the Mystery Machine and the light glow was just green Christmas Lights. The eerie piano music was just like the piano tune they heard Susan's student playing when they were at the house.

It turns out that she only wanted the Mystery Kids to return to fame. Andy and Mandy decide to call it quits, drop their instruments, and reconcile with Randy, much to Susan's shock and horror. When the gang asks why the two were at the cemetery, they tell the gang they were visiting Flash Flannigan's grave, and saying how much he meant to them. Murph offers another price for the Mystery Machine. Once again, the gang refuses. With Murph and Susan left at the city park, Murph wonders if Andy and Mandy still want their instruments, intending to collect them as souvenirs.

The gang heads to a drive-in movie theater to celebrate getting the Mystery Machine back. Just then, the gang thinks the van is haunted again and run off, when it's actually driven by Scooby.
