In Macau, a young woman wearing a panda ring visits a Pawn Shop.
Store Clerk: May I help you?
Mai Le: Do you have any jewelry? You know, like rings and stuff?
Store Clerk: Of course. Right this way.
They walk over to the ring section, and she admires a dragon ring.
Mai Le: Ooh. Let me see that one.
Store Clerk: I'm not supposed to show that to anyone.
Mai Le: Not even me?
Store Clerk: Oh, I guess it wouldn't hurt to let you look.
He shows her the ring and she looks at the store clerk.
Mai Le: How much?
Store Clerk: I'm afraid it's not for sale. I'm just holding it for a customer.
The phone then rings and he go to answer it. Mai Le puts the box down.
Store Clerk: Chu Chow's Trading Post. Ray speaking.
Mai Le leaves.
Mai Le: Well, thanks, anyways.
Store Clerk: Look, just tie it down until I get home.
Another person enters.
Store Clerk: I'm gonna have to call you back.
He hangs up the phone.
???: I've come for my ring.
Store Clerk: Of course.
He grabs the ring box and hands it to the man and he opens it, and the ring is gone and inside was the panda ring.
???: What is this?
Store Clerk: I don't understand. It was just here.
The man conjures white lightning from his fist. Outside, Mai Le hears the screams of the store owner as she looks at the dragon ring on her finger.
Daphne, Shaggy, and Scooby are at Chen's Internet Cafe and Tea House, Shaggy is ordering food.
Shaggy: Like, I'll take a double bacon latte, dry, no whip, with a triple pump or nacho cheese. Heh, heh. Can you make that?
Chen: Make it? I invented it.
Daphne was talking with Scooby.
Daphne: Tonight's the first time my parents will see Y/N and me as a couple. I just want everything to be perfect. I'm afraid they might disapprove of him. Thanks for listening.
Scooby: No problem.
The doors open and Velma and Mai Le come in.
Daphne: Velma, over here.
Velma: Those are my friends. Watch out for the skinny, frail-looking one.
They join the group.
Velma: This is Mai Le. She's here from China on a two-week student exchange.
Shaggy: Like, who did we exchange for her?
Velma: The school's weird girl, Hot Dog Water.
Meanwhile Hot Dog Water was eating noodles.
Hot dog Water: Oh, boy.
She farts.
Hot Dog Water: There isn't gluten in these noodles, is there? Probably should have told you I have a major gluten intolerance.
Back with the others, everyone was sitting down.
Daphne: Welcome to Crystal Cove, Mai Le. I think you're gonna love it here.
Scooby: Me, too.
Mai Le: Me, too.
Shaggy smiles at her. Chen comes by.
Velma: Chen, this is Mai Le. She's visiting from China.
Chen: Welcome. Please try one of my Szechuan pork ice-cream sandwich, on the house.
Mai Le reaches for one when Chen notices the dragon ring on her finger.
Chen: Uh, excuse me.
He walks away.
Daphne: You know, there's a delegate from China visiting Crystal Cove right now. Fred is showing him around town with his dad. My dad is hosting a dinner party for my boyfriend, Y/N- I love saying, "boyfriend"- You should come.
Mai Le: Will there be any cute boys there?
Daphne: Well, Y/N, my boyfriend, of course.
Shaggy: Like, a-hem.
Daphne: Oh, and Shaggy?
Mai Le: Then, I'll be there. For sure.
Velma whispers to Mai Le.
Velma: Sister, you're playing with fire.
Y/N then enters.
Daphne: There he is.
Daphne gets up and she pulls him aside.
Y/N: What's wrong?
Daphne: Are you free tonight?
Y/N: Yeah, why?
Daphne: My parents want to host a parent and they want to invite you to meet you properly.
Y/N: What's the dress code?
Daphne: Really you mean it?
Y/N: Yeah, I'm going have to meet them one day. May as well be now.
Y/N and Daphne smiles. Meanwhile Fred was with his dad and Mr. Wang there standing a photo cut out stand.
Mayor Jones: Mr. Wang, what you guys need is a theme, something that makes your little country stand out, something that says fun. Here in Crystal Cove, our theme is the World's Most Haunted Tourist Trap. I mean town. Folks can't get enough of it.
Fred: Everyone, say beef and broccoli.
The photographer takes the picture.
Mr. Wang: Fascinating. There is much we can learn from you.
Shaggy and Mai Le walk together.
Mai Le: You've been to China?
Shaggy: No, but my stomach has. Scoob and I get Chinese takeout every single week.
The two laughs as Velma grabs Shaggy and pulls him away.
Velma: Shaggy, you have to stop flirting with Mai Le.
Shaggy: Like, dude, I'm just bein' polite.
Velma: The last time you were that polite to me, I spent a month locked in my bedroom listening to "Now That's What I Call Breakup Songs 16."
Mayor Jones walks by the gang.
Mayor Jones: Mr. Wang, we better get you back to the hotel if you're going to be ready for the shindig tonight. Oh, pardon my French. "Shindig" is American for hootenanny.
Mr. Wang: I'm honored to attend your shindig.
Mr. Wang notices the dragon ring on Mai Le finger.
Mr. Wang: That's a lovely ring, Miss...
Mai Le: Le, Mai Le.
Mr. Wang: Where did you find such a treasure?
Mai Le: At some junk store.
Daphne: Dinner is at eight. Dress is casual.
The gang walks away with Mai Le. Soon after, at Daphne house Y/N and Daphne walks up to the door nervous.
Y/N: Ready?
Daphne nods and they enter, and they see Daphne's parents.
Daphne: Mom. Dad. This is my boyfriend, Y/N.
Y/N: Nice to meet you two again.
Y/N shakes their hands.
Barty: Hmm, good manners. He's better than the Jone's boy.
Y/N: You have a lovely home.
Nan: Thank you. Where are your parents?
Y/N: They are... no longer with us.
Nan: Oh, dear I'm sorry.
Y/N: It's fine.
Nan: I'll go start the food.
Nan and Barty walk off with her husband. Soon after, night came, and the gang was there along with Mai Le. The dinner was going well, as Shaggy whispers to Scooby.
Shaggy: Like, Scoob, swap seats with me, would you?
Scooby: Why?
Shaggy: So, I could be closer to the, uh, gravy.
Scooby: Here you go.
Scooby hands him the gravy.
Shaggy: Thanks. But I really want to be closer to the, uh... Baked Alaska.
Scooby hands it to him.
Shaggy: Scoob, just switch seats with me.
Scooby: Fine. Humph. Testy.
Scooby and Shaggy switch seats. Barty hits his cup with his spoon getting everyone's attention.
Barty: Mr. Wang, friends, Fred. I would just like to say-
The lights turned off.
Barty: Who turned off the lights?
Suddenly, a wizard appears amongst red lightning as Y/N grabs Daphne's hand and backs up and soon everyone else does.
Red Wizard: Do not disturb the Dragon's Heart, or you will pay the price. The Dragon's Heart belongs to no one. Whoever tries to claim it will die.
He begins to shoot red lighting around the room as they all go under the table and the red wizard looks at Mai Le.
Red Wizard: You have unknowingly brought grave danger to all who are near you.
He shoots lighting but misses as Shaggy is next to her.
Shaggy: I came down here to protect you, but now I seem to be paralyzed with fear.
Velma: What is the Dragon's Heart?
Suddenly the table goes flying with the chairs.
Nan: Somebody do something.
Fred: Way ahead of you, Mrs. Blake.
Fred pulls a rope and a head statue swing and hits a wall breaking it, and its eyes beep red and a net lower, but the red wizard escapes, and everyone is trapped in it.
Mayor Jones: Rumbling swamp crickets! What just happened?
Barty: I seem to be trapped in some sort of net.
Fred: Not just any net. That's a Brownsberger B-41- titanium-woven, aircraft-grade aluminum grommets. This baby is sharkproof.
Daphne: But why is it in our dining room?
Fred: I installed it last year for a situation just like this.
Y/N: You bobby-trapped Daphne's house?
Fred: I bobby-trapped all your houses for protection, and it's a good thing too. We almost caught that wizard.
Nan: Almost? You destroyed my dining room.
Fred: Hey, you can't trap an omelet without breakin' a few eggs. Am I right?
Fred pulls a rope, and the group is freed.
Mayor Jones: Mr. Wang, I'm so sorry about this.
Barty: Spare me. Things like this always happen when the Jones boys are around.
Mayor Jones turns to him.
Mayor Jones: What's that suppose to mean?
Mr. Wang: Thank you for this memorable evening, but I have had enough excitement for one night. It is time I returned to my economy lodging.
Barty: Daphne, I want your idiot friend out of my house!
Fred: Did you hear that? Your dad called me your friend. That's an improvement.
Y/N walks to Fred grabs him by the ear and drags him.
Fred: Ow! Hey!
Y/N: You are coming with me, and you are going to take down every trap that is in my house!
Y/N and Fred leave the room.
Velma: We should look for clues while the two are gone.
Scooby: Good idea.
Scooby sniffs and he sneezes.
Shaggy: What did you find, Scoob?
Velma: It's some kind of red dust.
Mai Le: That's not dust. It's tea, scarlet oolong, to be exact. This tea is very rare.
A fire goes in the air.
Velma: And flammable. There's only one place in Crstal Cove that specializes in rare, flammable teas.
At Y/N's home Y/N and Fred were taking down all the traps that Fred installed, it included multiple net, multiple cages, and multiple ropes. Y/N threw the final net into the pile that was filled with Fred's traps.
Y/N: Is that everything?
Fred: Yup.
Suddenly a trap goes off and Y/N is hung upside down.
Fred: Aside from that one.
Y/N: Fred, you have five seconds to untie me before I smack you.
After Fred untied Y/N, Fred got a call from Velma and told them what they found and told them to come pick them up. They did and they went to Chen's Internet Cafe and Tea House. Fred stalks the Cafe with a periscope.
Fred: Looks pretty quiet out there.
Velma: Fred, when did you install a periscope in the mystery machine?
Y/N: Oh, I don't know, probably around the same time he decided to install traps in our houses.
Daphne: What else aren't you telling us, Fred?
Fred: Nothing. I swear.
Daphne: Whatever. Where's my lip gloss?
She opens up the glove department.
Fred: Daphne, wait! No!
She opens it and Y/N seat goes flying as Y/N is launched out and he screams.
Fred: I guess there was one other thing I didn't tell you.
Meanwhile in the back of the van, Shaggy, Scooby, and Mai Le were together.
Shaggy: The key to a good stakeout is making sure you've got enough snacks.
He pulls out a bag.
Shaggy: This is Scoob's and my special snack sack we've got something for every food group- salty, sugary, jerky, and ice cream. Like, I recommend eating the ice cream first.
He gives a spoon to Mai Le a spoon, but Scooby does not get one as he watches Shaggy and Mai Le eat the ice cream. Velma turns to him.
Velma: I feel your pain, dog.
The doors then open and Y/N comes back a little bruised, and with dirty clothes, looking angry and he sits down.
Fred: I am so sorry, Y/N-
Y/N holds up a hand towards Fred.
Y/N: Zip it!
Suddenly white lighting strikes and it lifts the Mystery Machine up and begins to shake.
Shaggy: Let's get out of here!
Daphne kicks a door open.
Velma: This way.
They jump out.
Fred: Geronimo!
They then see a white wizard.
Daphne: It's the wizard from the party!
The wizard drops the van as they move out of the way. They run as red lighting strikes and see the Red Wizard.
Fred: No, wait. That's the wizard from the party.
Velma: Two wizards? What is going on?
Y/N: A wizard battle!
The two wizards fight each other as Shaggy and Scooby hide behind a corner.
Shaggy: Like, this would be so cool if I wasn't so terrified!
The two wizards make dragons, and they strike each other and knock each other back. The wizards charge at each other as Velma looks through binoculars and sees the White Wizard has three rings exactly like Mai Le's.
Velma: That white Wizard has three rings exactly like yours.
The two wizards continue to fight until the Red Wizard is knocked down and turns to the group.
Scooby: Uh-oh.
Shaggy: Like, I second that, Scoob.
Fred: Quick, everybody. Back in the van.
The gang run back to the van as the White Wizard chases them as Fred tries to start up the van.
Fred: Come on. Come on.
The White Wizard grabs Mai Le.
Mai Le: Help!
Shaggy: Mai Le!
Shaggy grabs her but loses grip as she flies off with the wizard. The van starts up as they chase them.
White Wizard: The ring, give it to me!
Fred: Shaggy, I need your snack sack. Daphne, slide over and put the snack sack on your seat.
Daphne: Ok. Ready to launch.
The snack sack is fired from the ejector seat, as a surface-to-air missile and they save Mai Le.
Shaggy: Like, we got her!
They drive off pursued by the White Wizard, but the Red Wizard recovers.
Y/N: Fred, speed up! He's coming!
The Red Wizard attacks him, and they clash, and the two wizards are gone and the gang escapes. Fred drops off Velma and Mai Le at Velma's home.
Velma: Are you okay, Mai Le?
Mai Le: I am now, thanks to Shaggy. I owe you my life.
Shaggy: It was, you know, like, nothin'.
Velma looks at him.
Shaggy: What? Is there somethin' in my teeth?
Velma: Come on.
The two leave as the van drives off. They go into Velma's room.
Mai Le: So, what's the story with Shaggy? He's cute.
Velma: Stay away from Shaggy. He has dog issues.
Mai Le: I don't know what that means.
The lights turned off.
Velma: Now what?
The White Wizard crashes through the window as the two girls run off.
Velma: Quick, Mai Le, this way!
The two take cover as the White Wizard trashes the living room.
White Wizard: Give me the ring! It is the key to possessing the Dragon's Heart.
Mai Le gets up.
Velma: What are you doing?
Mai Le spin kicks him to the ground.
Velma: Jinkies. You go, girl.
Mai Le and the White Wizard fights as Shaggy comes over reading a Chinese dictionary.
Shaggy: Mai Le-
He opens the door as the two girls run out as the White Wizard grabs Mai Le and takes the ring.
Mai Le: My ring!
The White Wizard disappears.
Shaggy: That is so not how I imagined this happening.
Soon after, the gang was at Chen's Internet Cafe and Tea House and Velma was doing research.
Velma: I have searched every corner of the internet, and I cannot find anything about the Dragon's Heart.
Daphne: And why did he steal Mai Le's ring? He already has three of them.
Chen: The wizard has all four rings?
Chen goes over to the gang.
Y/N: Chen, do you know something we don't?
Chen: Well, I suppose it's time you should know. That Red Wizard who's been popping up out of nowhere, it's me.
Shaggy and Scooby: What?
Chen: When I was a young grasshopper in China, I was entrusted with a priceless ruby called the Dragon's Heart. Centuries ago, the ruby was encased inside the great Jade Dragon. Legend has it that you must use four sacred rings to gain access to the Dragon's Heart.
Shaggy: But, like now the White Wizard has all four rings.
Velma: If only we had that Jade Dragon, we could use it to lure him...
Fred: Into a trap.
Chen: You're in luck, because the Jade Dragon is right over there.
He points to the Jade Dragon.
Fred: Gang, it's trappin' time.
Soon after, Chen closes his store with a window open.
Chen: I sure hope no one notices this window is gone and steals my Jade Dragon! Oh, well!
He leaves as the White Wizard appears blasting the doors open and the trap activates shooting missiles in the air triggering the sprinkles. Fred holds up a Scooby Snack and throws it in the air.
Fred: Scooby Snack, go!
Scooby jumps backwards to catch it as he lands on a board, and it sends Daphne, Velma, and Y/N flying in the air as they cut a lantern, and it falls on the White Wizard as the three lands on the ground. Fred rips off the plastic and the wizard is trapped.
Fred: The Brownsberger B-41. It's the trapper's trap.
Mayor Jones: Spicy giblet ponies, Fred! Why do you have a Geisha tied up in here?
The gang looks and sees Mayor Jones.
Mayor Jones: You know they belong downtown in Crystal Cove's Geisha House of Terror.
Y/N: Wait, he's not a Geisha. He's a wizard.
Fred: Or at least that's who he's pretending to be.
Y/N takes off the mask and it is revealed to be Mr. Wang.
All: Mr. Wang?
Scooby: Big surprise.
Mayor Jones: What?! Wang?! Why?!
Mr. Wang: I've searched for the dragon's heart all my life. I tracked it to your silly little town, and it was almost mine. Mine!
Mai Le: You won't be needing these anymore.
She takes the 4 rings off of Mr. Wang.
Daphne: Now it all makes sense. Mr. Wang used his supposed research trip to Crystal Cove as an excuse to hunt for the dragon's heart. When he saw that Mai Le was wearing the fourth dragon ring, he knew he was close. Mr. Wang posed as the evil White Kung Fu Wizard to steal the fourth dragon ring from Mai Le, but Chen pretended to be a Red Wizard in an effort to stop him. Velma: After the wizard battle downtown, Mr. Wang came to my house in one last effort to get the ring. Shaggy: But how did he make himself fly?
Chen: Oh, the same way I did...
He takes the White Wizard costume off of Mr. Wang.
Chen: ...jetpack.
The gang: Oh! Of course.
Daphne: And the magic lightning bolts?
Velma shows Mr. Wang's hand.
Velma: Homemade Tesla coils. Genius!
Mr. Wang: It was the perfect plan. That ruby is priceless. I was going to be rich! And I would have gotten away with it if it weren't for you-
Fred put on the masks Mr. Wang.
Fred: Save it, Wang. We've heard it all before.
Mr. Wang is then taken away as Mai Le talks with the gang.
Mai Le: I can't thank you enough for what you've done for me. Oh, and before I forget, Chen rightfully should have these.
She presents the four dragon rings and gives them to Shaggy.
Shaggy: Like- heh. So now that it's over, Mai Le, um, I was wondering if we could, like, you know, um... like- how do I say this?
Scooby: Go on a date?
Shaggy: Right, heh. Thanks, pal.
Mai Le: Oh, Shaggy, I'd love to, but it's time for me to return to China.
Shaggy: China? Like, when do you leave?
A taxi pulls up.
Mai Le: In ten minutes. Goodbye, everyone. I'll never forget you, especially you, Shaggy.
The taxi drives off.
Shaggy: I guess this is what it feels like to have your heart broken.
Velma: You know, one of the things I always wanted a boy to do is surprise me and see me off as I was leaving on a plane.
Daphne: Yeah. That is romantic.
Shaggy: But, like, I don't even know what flight's she's on.
Y/N: It's Crystal Cove, Shaggy. We only got one plane.
Fred drives up with the Mystery Machine.
Fred: Come on, gang. I'll drive.
Shaggy: Thanks, guys. And, um, thanks, Velm.
At the docks, a boat departs with silhouette going onto it. Inside the ship, the figure opens a case and sees the Dragon's Heart.
???: Finally, mine. So long, Mystery Incorporated.
The ship turns hard left, the figure accidentally drops the ruby, Shaggy arrives and catches it.
Shaggy: Hello, dude. Or should I say Mai Le? I went to the airport to see you off, but you weren't on the plane. It was always about the ruby, wasn't it? You just used us to get Wang out of the way so that you could get the other rings.
Mai Le: That's right. While you and your idiot friends were explaining Wang's plan, I opened the jade dragon and took the ruby. The dragon's heart belongs to me!
Shaggy: Fine. Come and get it.
Mai Le destroys the table with her strong fist.
Shaggy: Zoinks!
Shaggy runs as Mai Le chases him. Mai Le runs on the deck and triggers Fred's trap and she is captured.
Mai Le: Let me down, you idiots!
Scooby: You okay, Shaggy?
Shaggy: Was everything about you a lie? Like, even us?
Mai Le: Sorry, dude.
Velma: He's too good for you, dog issues or no dog issues.
Mai Le: I still don't know what that means.
Daphne: Mom, dad, you can come out now.
Daphne's parents come out of hiding.
Fred: Thanks again, Mr. and Mrs. Blake, for letting us disguise your boat as Mai Le's escape boat.
Barty: Well, I have to admit, Fred, your cockamamie trap actually worked.
Fred: That's awfully nice of you to say, sir.
Barty turns to Y/N.
Barty: L/N.
Y/N: Yes, sir?
Barty: From now on, I'll trust you with my daughter. But no funny business and have her home by eleven.
Y/N smiles.
Y/N: I will, sir.
Nan: Just one question. How did you know that Mai Le would step right in the middle of your trap?
Fred: I didn't. That's why I set traps all over this boat.
Daphne's Parents: You did what?!
Three traps activate as Daphne's parents and Y/N are caught in Fred's traps.
Y/N: Oh, come on!
Barty: Fred Jones, you buffoon!
Scooby: Yeah. Buffoon.
Scooby laughs.
