- Velma Dinkley: [examines a hair] Trace amounts of hair oil, twelve-year-old scotch...
- Daphne Blake: Ugh, is the bad guy my dad?
- Shaggy Rogers: I guess our new movie is an origin story.
- Scooby-Doo: Every hero should have one!
- Shaggy Rogers: I want the Rock to play me!
- Scooby-Doo: ...That'll never happen.
- Velma Dinkley: [listing Dastardly's crimes] And apparently he's been stealing Netflix by using his mother's account.
- Daphne Blake: [gasps] That is not fair for the rest of us who have to pay for Netflix.
- Fred Jones: You have to *pay* for Netflix?
- Dick Dastardly: Join me, Scooby-Doo, and I will show you how to harness your destiny and become the most important dog in the world!
- Scooby-Doo: No thanks, Dastardly!
- Dick Dastardly: Oh please, my friends call me Dick!
- Scooby-Doo: Rokay, Rick.
- Dick Dastardly: No, I'm not a Rick. I'm a Dick, with a D.
- Scooby-Doo: Rick, with a D.
- Dick Dastardly: [grunts] D-d-d-dick.
- Scooby-Doo: Ra-ra-ra-Rick.
- Dick Dastardly: Dick, Dick, DIICCCKK!
- [notices that Scooby has fled]
- Dick Dastardly: Drat.
- Shaggy Rogers: Drop some F-bombs!
- Blue Falcon: Hey man, whoa, let's keep it PG!
- Shaggy Rogers: No! Falcon bombs!
- Velma Dinkley: How is it that you know so much about superheroes and so little about the metric system?
- Fred Jones: Because I am an American man.
- Dick Dastardly: Scooby Dooby-Doo... Where are you...? Come now, don't be scared. I love dogs. Had one to myself once, an ill tempered brute with a ghastly underbite who STUNK. And caused me endless headaches! He's lost now...
- Velma Dinkley: [examining the bowling pin robot] It's fully autonomous and capable of modifying its external appearance. I'd like to shake the hand of whoever created this.
- [Fred and Daphne give her a look]
- Velma Dinkley: And then, y'know, throw that hand in prison for trying to kill our friends. Right? Am I right?
- Young Shaggy: We'll go in the Haunted House this one time. But we're not going to make a habit of this, right, Scoob?
- [last lines]
- Velma Dinkley: [after being informed of a new mystery] Looks like we're on the case.
- Fred Jones: Let's hit it.
- Daphne Blake: [to the little robot] Hey, Dusty! Watch the shop please?
- Shaggy Rogers: [to Scooby] What do you say, buddy?
- Scooby-Doo: Let's Scooby-Dooby-Doo it!
- Velma Dinkley: [examining a hair] Maybe this can lead us to our culprit.
- Fred Jones: What are you doing? Touching it with bare fingers. Bleugh!
- Velma Dinkley: Grow up, Fred. You know how many hairs the average human eats every day without knowing it?
- Fred Jones: If it's more than zero, I don't wanna know.
- Velma Dinkley: It's more. Much, much more.
- Shaggy Rogers: [after returning from the Underworld] Zoinks! I guess friendship really did save the day.
- Scooby-Doo: Rhaggy!
- Shaggy Rogers: Scooby-Doo!
- [they hug each other. The rest of the gang walk up and meet them in a group hug]
- Daphne Blake: I love you guys. You gave us quite a scare, Shaggy.
- Shaggy Rogers: [puts Scooby's collar back on] Well, it takes more than a three-headed monster to keep me away from my best bud.
- Velma Dinkley: [pointing to Fred, Daphne, and herself] Tank, empath, brain. I finally figured out what you guys are. You're the heart of Mystery Inc.
- Velma Dinkley: Daphne, what are you doing?
- Daphne Blake: [leaning back in a chair] If Scooby and Shaggy were here, they would accidentally sit on a rigged chair. Or bump their heads against a wall. And it would open a secret passage out of here.
- Velma Dinkley: They *are* surprisingly effective goofballs.
- Daphne Blake: [falls over] Whoa! Ow.
- [just then, they notice the vacuum-head robot walking by, sneezing]
- Daphne Blake: Aw, poor little thing.
- Velma Dinkley: Uh, Daph, he's not on our side.
- Daphne Blake: [bends down to him] Do you need help?
- [the robot jumps back in fright]
- Daphne Blake: It's okay. I want to help you.
- [the robot timidly approaches Daphne, who removes the vacuum part of its head, dumps the dust out, then puts it back on]
- Daphne Blake: Better?
- [the robot breathes through its mouth, jumps for joy, then runs through a gap in the cell door and hugs Daphne]
- Daphne Blake: Aw, you're welcome.
- Velma Dinkley: Hey, hey. Do you think you can help us get out of here, little buddy?
- [the robot walks out through the gap in the cell, extends his legs, produces a key from his hand and unlocks the door]
- Fred Jones: Cool.
- Daphne Blake: [being cornered by Cerberus] AAH!
- [just then, the vacuum-head robot and all the other robots descend from the ship and swarm Cerberus]
- Daphne Blake: Look out!
- [Cerberus swats the robot that's carrying the vacuum-head robot. The little robot falls and lands in Daphne's arms]
- Daphne Blake: Are you okay, little guy?
- [the little robot nods. Daphne kisses him on the cheek and he blushes]
- Young Fred: [to Young Shaggy and Scooby] Guys, we gotta do something!
- [runs forward while Young Shaggy and Scooby duck into the closet to hide]
- Scooby-Doo: [reuniting with the gang] You guys are alive!
- Shaggy Rogers: Scooby-Doo!
- [hugs him]
- Daphne Blake: Scooby!
- Fred Jones: Ya-hoo!
- [the rest of the gang comes in for a group hug]
- Daphne Blake: Oh, thank goodness. The gang is finally back together.
- Shaggy Rogers: [to Scooby] Buddy, I never meant to...
- Scooby-Doo: I know. Me neither.
- Young Shaggy: [to Daphne] Cool Wonder Woman costume.
- [turns to Velma]
- Young Shaggy: And are you... Harry Potter?
- Young Velma: I'm Ruth Bader Ginsburg, obviously.
- Young Shaggy: Which house is she in? Hufflepuff?
- Young Velma: She's a Supreme Court Justice.
- Young Shaggy: [disappointed] Oh. Slytherin.
- Simon Cowell: Every successful group requires hard work and determination. Identifying potential is what I do; and you have got it!
- Simon Cowell: Fred, you're the tank. The muscle.
- Fred Jones: Cool.
- Simon Cowell: Daphne is the people person. The impact.
- Daphne Blake: Awwww.
- Simon Cowell: And Velma has the smarts and technical savvy.
- Velma Dinkley: Thanks!
- Simon Cowell: But you two aren't even listening. You're eating a clownishly oversized sandwich.
- Shaggy Rogers: Like sorry man, you lost me at 'hard work and determination.'
- Scooby-Doo: But you got us back at 'sandwich.'
- Young Fred: [introducing himself to Young Shaggy and Scooby] I'm Fred. This is Velma.
- Young Velma: Hi.
- Young Fred: And that's Daphne.
- Young Daphne: Hey.
- Young Shaggy: I'm Shaggy. And this is Scooby-Doo.
- Scooby-Doo: Nice to meet you.
- [Young Daphne holds out her arms and Scooby runs up to her and licks her cheek]
- Scooby-Doo: [after Shaggy is sent to the Underworld; crying] Rhaggy...
- Velma Dinkley: Are we missing something? "A pair whose friendship forever grows."
- [sniffs and wipes her eyes]
- Velma Dinkley: Could it mean something else?
- Daphne Blake: [choked up] I think it means that Scoob and Shaggy's friendship will live on. Whether they're together or not.
- [hugs Scooby]
- [as the ghost chases Young Daphne around the room, Young Velma looks up to see him connected to a pulley system on the ceiling]
- Young Velma: Fred, look!
- [Young Fred takes an ax off the wall. The ghost corners Young Daphne just as Young Fred throws the ax, cutting the cable]
- Ghost: Uh-oh.
- [falls to the ground]
- Young Daphne: Velma!
- [throws her rope to Young Velma]
- Young Velma: Got it!
- [they use it to tie up the ghost]
- Ghost: Hey! What're you-?
- [Young Fred charges at him and tackles him to the ground]
- Young Fred: Gotcha!
- [Young Daphne and Velma jump on top of the ghost too]
- Young Daphne: Jeepers. It's a Halloween mask.
- [rips it off to reveal...]
- Young Velma, Young Daphne, Young Fred: Mr. Rigby?
- Young Shaggy: Uh, guys?
- [shows the secret room they found]
- Young Shaggy: I think we just found the world's smallest Wal-Mart.
- Young Shaggy: [after he and the gang discover a haunted house for the first time] Guys, I think we found a new Wal-mart.
