At an amusement park we see a group of kids getting on a hang gliding ride as they got on it the ride began as a boat was going through the water as the glider was in the air suddenly a green monster came on a jet ski

Roller Ghoster: *evil laugh*

It came at the boat and cut the rope for the glider ride as the glider went into the water as the monster was seen riding away laughing evilly. We now see you and the others as the mystery machine and rustbucket were seen driving through the road.

(Y/N): So are we there yet?

Ben: No idea.

(Y/N): So Shaggy what kind of coaster did you design?

Shaggy: It's a ride that is themed after an all you can eat buffet.

Max: Heads up everyone we're getting close to the park!

(Y/N): Awesome.

You all then arrived at the amusement park as you all walked to the entrance you saw were two girls at the entrance.

(Y/N): Those must be the people we're supposed to meet.

Then you all walked towards them.

Girl: You must be Shaggy right?

Shaggy: Like that's me.

Girl 2: Congratulations on winning the design your own ride contest.

Girl: We're actually building your ride right now.

(Y/N): You designed a coaster for a contest? Nice!

Shaggy: Like thanks, anyway where do we meet Chris and Terry? Those guys are the best.

Ben: Uh, Shags I think they're Chris and Terry.

Terry: Your right I'm Terry and this is my sister Chris.

Shaggy: Like you guys are girls?

(Y/N): I'm assuming their names must be short for Christina and Teresa?

Ben: Probably. So you two made all these rides?

Terry: My sister works on the designs I help bring them to life.

(Y/N): Well I can say is you two did a pretty amazing job if I say so myself.

Terry: Oh, well thank you.

Then we now see you and the others at the park as Chris and Terry gave you all a tour of the park.

Terry: *hands you all VIP passes* These VIP passes will get you into every ride in the park, oh and the food court.

Shaggy: Like free food?

Terry: Sure, help yourselves.

Then Scooby and Shaggy smiled knowing that they can now have access to free food at the food court.

Terry: Your ride is almost done, We'll show you.

Then Chris and Terry led scoob and shaggy to the food court.

Shaggy: Uh scoob and I will catch up with you guys later.

(Y/N): Uh Chris and Terry you two don't mind if I come with you?

Terry: Not at all.

(Y/N): Cool, uh I'll see you guys later.

Then we see you, shaggy and scooby head out of the food court as scoob and Shaggy had a lot of food in their hands.

Terry: Where did you get the idea of a combination of a ride and an all you can eat buffet?

Shaggy: Like, the idea just came to me.

(Y/N): So you two made every ride here

Chris: Well, Terry designs them I just bring her ideas to life.

(Y/N): Well I have to say your sister did an amazing job and you got some pretty great ideas.

Terry: Thanks.

(Y/N): Your welcome so how does this ride go? Just curious to know.

Terry: The ride starts at the buffet line

As she explained the ride to you shaggy and scooby were fighting over a sandwich

Terry: But lately we've been having a few accidents.

(Y/N): Accidents?

Chris: Yeah, for some reason some of the rides broke down.

(Y/N): Hhm? Sounds like a mystery. Shag, Scoob I'll go look for clues you guys see if you can't find the others.

Shaggy: Ok.

Then you walked off as you then hid and changed into your hero outfit as you selected an alien.

(Y/N): Let's go with a thinker.

You slapped the watch as you then turned into grey matter.

Skurd: Grey matter?

(Y/N): I'm going with brains over brawn I'm going to look at some of these broken down rides.

Skurd: Genius to find clues of the suspect.

(Y/N): Exactly. Someone must be sabotaging the rides, but who?

Skurd: I have my doubts on Terry. Something seems off.

(Y/N): Yes but Skurd let's give grey matter a boost for flight.

Skurd gives Grey Matter Big Chill's wings and you take off now let's see how Fred and the girls are doing

Ben: What's taking them so long?

We then see a short red headed kid getting angry

Eddie: What do you mean I'm too short?

He was talking to a man.

Man: Sorry it's the rules, maybe next time when your taller.

Then the kid walked off angry that he couldn't go on a ride as they got on it.

Kara: At least there's no long lines.

Velma: Amen sister!

Then something hit Velma in the face as she saw you as grey matter with big chill's wings

(Y/N): Ouch! Note to self: work on the landings.

Velma: (Y/N)? What are you doing as Grey Matter? Is something wrong?

(Y/N): Yes, apparently some of the rides have broke down and me and Skurd have a suspicion that someone must be sabotaging them.

Daphne: Really? Have you two seen anything out of the ordinary?

(Y/N): Hold that thought Daph I think I see something outside the ride!

You looked to see a green furred monster slashing at the controls of the ride.

Kara: He's breaking the controls!

The cage over the fan opens and starts to slow down as the creature runs off.

(Y/N): Time for an upgrade.

You then changed into upgrade and then you were now engulfed in blue energy and became Omni Enhanced as the green circuitry became blue

Fred: Everyone hold on!

You then went to stop the fan from chopping your friends into minced garlic as you then made the fan stopped immediately as you then stretched your body to catch your friends as a net.

(Y/N): Well guys looks like we got a mystery on our hands.

Then you changed back as we see a hatch for the ride opened as we see a man.

Sam: Are you kids alright?

(Y/N): Yeah, we're alright but what was that thing that trashed the ride?

Sam: I can't believe it happened again.

Jessica: Again?

Sam: The folks have been seeing a green creature running around destroying all the rides! They call him The Roller Ghoster I've never seen him myself.

(Y/N): I saw him trashing the controls moments ago to this ride. It's like it's been doing this for a reason. Hey, what's this?

You notice a bit of green hair in the controls

(Y/N): Green fur. It's definitely a clue.

Jessica: Thanks for saving us (Y/N).

(Y/N): I had no idea Upgrade could go Omni Enhanced but anytime. Ok, guys, it's time to split up and look for clues!

Diana: Yes, let us split ourselves!

Velma: Split up.

Diana: Yes that.

(Y/N): Diana, Jessica, Kara, Karen, Babs, and Zee you're with me. Freddie, you, Velma and Daphne go talk to Terry and Chris to see if they know anything about the Roller Ghoster.

Fred: Ok. Let's split up gang.

Then we see you and the girls in their hero outfits as you were searching around for clues. Then you look at your watch.

(Y/N): I'm gonna go alien just in case.

Karen: Ok try brainstorm.

But they saw you turn into Abatoon instead

Jessica: And he's Abatoon.

(Y/N): Ok let's get my handy magnifying glass.

You reach into your pocket as you then pulled out a mallet.

(Y/N): That's not it.

You threw it as it was heard to hit a person.

Man: My leg!

You then reached into your pocket and pulled out a banana peel.

(Y/N): Not it either.

You threw it as it was seen on Kara's face

Kara: Hey! Watch where you throw things!

You then pull out a pic of Velma in a bikini.

(Y/N): *blushes and laughs nervously* Uhhh, how did that get in there?

You quickly put the photo back and then you pulled out a magnifying glass as you put on a detective hat and had a pipe in your mouth as bubbles were seen coming out of it.

(Y/N): Now everyone let us solve this mystery.

You then walked around as you examined things with the Magnifying glass as you were searching for clues and trying to find the roller ghoster.

(Y/N): Come on everyone we must find the monster and quickly.

You then dashed off to find the culprit as you looked through a roller coaster as you were riding it and looked around for the monster.

(Y/N): He's not here on the roller coaster!

We then see you on a Ferris wheel

(Y/N): Nope not on the Ferris wheel either!

Then we see you leaving the cotton candy stand as you were eating cotton candy.

(Y/N): He's not at the cotton candy stand either.

Kara: So how's detective work going Sherlock?

(Y/N): Terrible. I haven't found a single clue aside from the fur from earlier

Then a whistle was heard as we see two alien dogs ran to you as they transformed into aliens that looked like clowns as they saw Khyber walk up to them.

Kara: Who's that?

Zee: and are those clowns?

Then you made ten of yourself as you faced Khyber.

(Y/N): Khyber, and It looks like he got his pets a new form.

Khyber: That is correct and it is an interesting creature, the Corydon, native to the planet Vivera.

(Y/N): That's Abatoon's home planet.

Khyber: Where it's the natural predator of a Viverasapien.

(Y/N) 2: That's Abatoon's species.

Khyber: Yes and there is something you should know about it.

Then you saw the two Bepclowns as they both made five of themselves each as there was now the same total of your Abatoons.

(Y/N): Me and my big mouths.

Kara: Oooh I'm so scared. Come on you guys we can take on a bunch of clowns.

Then a Bepclown stretched its arm at Kara punching her square in the face as she was sent to a cotton candy stand as her head was in the cotton candy as she got up she had cotton candy in her hair as it looked like an Afro.

Jessica: You ok?

Kara: I'm fine.

(Y/N): *laughs and points at Kara* You look ridiculous! You look like you have cotton candy for hair! HAHAHAHAHAHAHAHAHAH!

Then Zee gave Kara a mirror as she saw her reflection as her eyes widened to see how she looked as she saw you on the ground laughing as you were pounding your fist on the ground.

Kara: Stop it! It's not funny!

Babs: It's a little funny.

Then you placed a red nose on Kara as she looked like a clown with it and honked it then Kara shook the cotton candy off her head and got the red nose off of her.

Kara: Uh can we fight now?

(Y/N): Yeah.

Then the clowns came at you as you then ran for it as you ran from them as you were seen at the bumper cars as they were after you on bumper cars as you drove away as you saw the other five coming at you as you then lifted up as the clowns then bumped into each other, we then see you at a ball throwing game as the clowns came to the game as they then saw kids with baseballs in their hand.

(Y/N): Ok time for the bonus level!

They started to throw baseballs at them as it hit them in the face as they then fell down and became two as you then ran from the as you then were cornered as they walked up towards you.

(Y/N): I wouldn't stand there if I were you.

They were confused as then a giant piano came falling down and fell on the two crushing them as they were seen popping out with piano keys in their mouths as you then grabbed the two and placed them in a cannon and fired it sending them far away. Meanwhile with shaggy and Scooby they were seen at a ride as they were in the ball as it begins scooby saw the roller ghoster as he had clippers as he cut the rope slightly

Roller Ghoster: *evil laugh*

As the ball launched the rope broke sending the two in the air as they were heard screaming as you heard them.

(Y/N): It's shaggy and Scooby their in trouble! *pulls out a bugle horn and blows it* Charge!

You then ran at fast speed to where shaggy and Scooby were as they were seen rolling around the park as you were looking for them they ran over you as you were stuck on the ball and saw Scoob and Shaggy and saw you were heading to the edge of the park.

(Y/N): Guys run in the opposite direction to stop the ball.

Then they ran as you were seen running to slow the ball down as you then pulled out an anchor and threw it to stop you guys as you then got the two out.

(Y/N): You ok?

Shaggy: We're fine.

Then Fred and Daphne came to you guys.

Fred: What happened?

(Y/N): *changes back* I think the roller ghoster did this, he's struck every single ride here there's no trace of him to be seen.

Then Daphne looked to see something as she smiled at it.

Daphne: Rocket Coaster! It's the fastest ride ever. Must. Ride. Coaster!!!

Shaggy: I guess the thrill of riding roller coasters just became a girl thing.

(Y/N): Are you ok Daph? Your not acting like yourself.

Daphne: Oh I'm fine. But we have to ride this coaster!

She grabbed your arm and took you to the Rocket Coaster as we see the same kid before at it.

Eddie: Why?! Why?! Why?!

Man: Sorry kid. Go ride the bumper cars.

Eddie: I'll get even, you'll see. You'll all see!

(Y/N): Hmm.

Then we see you all getting in the ride as Velma was seen running to you.

Velma: Guys Wait, I think the rides are being tampered for a reason.

(Y/N): Exactly, that's what we're counting on the ghost to do.

Daphne: Ghost, Schmost. This is gonna be supersonic!

Velma: But...

Then the door closed on Velma as she was now on the seat as the ride began as the seats clamped you all in firmly.

(Y/N): Welcome aboard Velma.

The ride began as you all went super fast as Daphne was enjoying this then we see the roller ghoster at the track of the ride as he had a wrench and began to loosen the bolts on the track.

Daphne: Gforce! Gforce! Gforce!

(Y/N): Wow, and I thought Wanda was nuts!

Lady Deadpool: I heard that buster!

(Y/N): Sorry sweetie! *sees the track* Guys! The track!

You saw that part of the track was gone as you all were then seen flying off track and into the water as you then went to upgrade and merged with the rocket and got it to shore as you changed back and opened the rocket up and got the others out as Chris and Terry were seen as they came to you all.

Terry: What happened?

(Y/N): The roller ghoster did it again.

Chris: The rides are ruined.

As you were looking at her you noticed something as you walked towards it and picked up a wrench.

(Y/N): What's this? A wrench I wonder where this came from?

Then Chris came and took it from you.

Chris: Gimme that it's mine.

(Y/N): Then what is it doing here?

Then everyone looked at her as she saw them looking at her.

Chris: I didn't do it it's just me wrench.

Then she walked away.

(Y/N): Guys I think I have an idea on catching the Roller Ghoster.

We later see you, Shaggy, and Scooby walking around the park.

(Y/N): Well we better call the police since we know who the roller ghoster is. right guys?

Shaggy: Like, yeah

Scooby: Reah.

(Y/N): We'll just be heading to the pay phones and call 911.

You were now at the payphone.

(Y/N): Ya think anyone thought it was suspicious?

Shaggy: Like not at all.

(Y/N): Now that the culprit thinks we're calling the cops they'll come to us.

Roller Ghoster: *growls*

(Y/N): Guys please tell me that's one of your stomachs.

Shaggy: Not mine.

Scooby: Ruh-Uh.

You turned to see the roller ghoster was behind you as you then ran away as scoob and shaggy followed you as you ran into the skate park as the others were waiting as the monster ran in they threw the nets but they only caught each other as we see you, Scoob and Shaggy run past them as you ran into the rentals as you and shaggy had skateboards and Scooby had roller skates as the roller ghoster had roller skates as well as you all skates through the park as the monster was after you three skates away as the monster chased you through the park you then went to a ramp as you stopped and the monster passed by you and went up the ramp and was in the air as he landed into a tent with stuffed prizes

(Y/N): Now if my suspicions are right the Roller Ghoster is Terry!

Kara: Or probably Chris!

She took the mask off to reveal it was actually Terry all along.

Everyone: Terry?

Velma: Just as we suspected.

Then we see Chris coming to you guys.

Chris: But why would my own sister frame me?

Velma: Maybe because she was jealous.

Terry: It's true, I spent all the time bringing your crazy designs to life, but I never get to build any of my own.

Chris then looked at Terry.

Terry: Do I get any credit or even a thank you?

Chris: I never thought of that.

Terry: You never thought at all! You were easy to frame.

(Y/N): Too easy. That's what tripped you up.

Velma: He's right you knew the wrench was too obvious a clue.

Daphne: And the green fur, green hair? Please!

Fred: Sort of a green herring?

Shaggy: Oh never go for green herring man. It isn't fresh.

(Y/N): Your plan to sabotage the rides so your sister would be blamed for it and you could take control of the park so you can build any ride you want.

Terry: And I would of gotten away with it if it weren't for you meddling kids!

Velma: Technically you did get away with it.

Kara: She did?

(Y/N): Yeah no one got hurt and she made sure that everyone was still safe. The perfect crime.

Fred: And she didn't do anything illegal.

Daphne: Just rude.

Chris: I'm so disappointed in you Terry, I'm telling mom.

Terry: No wait Chris! Let's not be hasty. Mom doesn't need to know about this! Wait!

Then terry chased her sister trying to keep her from telling their mother as the Eddie came to you.

Eddie: Hey, how come I wasn't a suspect?

(Y/N): You were too small to wear the costume. But you know what you're not too small for?

We then see you, Scooby, Shaggy, Peni, and Eddie on a ride called "All you can hurl" supposedly the ride Shaggy designed.

Eddie: Thanks you guys!

(Y/N): No problem kid.

Then we see you all go through the ride as you then past the others at water got them all wet as you then saw that the track was unfinished as you all screamed as you all were plummeting to the ground as a parachute opened up on the cart of the ride as you floated down.

Eddie: Hey! We're about to land on a giant hot fudge sundae.

As you all landed to the sundae spoons came out.

Shaggy: The best rides today are interactive, we're gonna have to eat our way out!

Then we see you all go into the sundae as scooby doo piped out covered in ice cream as he licked it off of him.

Scooby: SCOOBY DOOBY DOO!!

Next time is a clash of man versus reptile because the Glasburgh Dragon is next!
