- [Scooby accidentally hits Shaggy in the face while displaying karate movements]
- Shaggy: Hey, Hong Kong Fooey. Watch the fists of fury.
- Creature: I've got a bag of... uh... hamburgers for you. All you have to do is to come out into the dark shadowy part of the woods, where no one can see you.
- Scooby Doo: [excited] Okay!
- Shaggy: Hey, you guys, look. I know I'm just the dude that carries the bags, but it seems to me we all play an important part in this group. I mean, we're just like a big, delicious banana split. Fred, you're the big banana; Daphne, you're the pastrami and bubble gum-flavoured ice cream; and Velma, you're the sweet-and-sour mustard sauce that goes on top.
- Scooby Doo: Mmm-mm.
- Shaggy: That sounds pretty good, doesn't it?
- Velma: You know what, Shaggy? You've really put it into perspective for me.
- Shaggy: Thanks.
- Velma: I quit!
- Shaggy: NO!
- Daphne: No way! You... you can't quit! I was gonna quit in, like, two seconds! And now everyone is gonna totally think I copied off the smart girl!
- Fred: Now, wait a minute. wait a minute. Maybe I quit. I do. Yeah, I quit!
- Velma: I'm outta here!
- Daphne: Good riddance.
- Shaggy: Don't... no! Don't go. Come on, guys, don't do this! Please, don't go.
- Scooby Doo: Do I quit?
- Shaggy: No, Scoob... friends don't quit. Well, it looks like it's just you and me for a while, buddy, old pal.
- Voodoo Maestro: Whatever you do, don't go into that spooky island castle.
- [points to castle]
- Daphne: Ah-ha! You want me to go into that castle!
- Voodoo Maestro: Didn't you hear what I just said?
- Daphne: But you're scary, and you knew I'd do the opposite of what you said. So you told me not to go up to that castle so I would go up to that castle where you've set a trap to capture me.
- [thinks for a second]
- Daphne: Unless... unless you knew I'd figure it out. So you told me not to go up to that castle so I would think that you wanted me to go so I wouldn't go, just like you didn't want me to. I'll find out what your hiding in that castle. You'll see.
- [Daphne walks away]
- Voodoo Maestro: [to himself] What in the world...?
- Fred: Scrappy, I told you no urinating on Daphne.
- Scrappy Doo: It was an accident!
- Fred: You were marking your territory!
- Shaggy: Who's your best buddy?
- Scooby Doo: Raggy.
- Shaggy: That's right. And who's my best buddy in the whole wide world?
- Scooby Doo: Rooby Doo.
- [trapped in hot dogs]
- Scooby Doo: What do we do?
- Shaggy: Do what we do best Scoob, eat.
- [Scooby bites one]
- Scooby Doo: It's plastic.
- Shaggy: What do you care? You drink out of the toilet.
- Scooby Doo: So do you.
- Fred: Yo-Yo the bi-atch was like what? And I was like layta on.
- Shaggy: Fred.
- Fred: Yo. What up, dawg?
- [to Scooby]
- Fred: And, uh... dog?
- Scooby Doo: Keepin' it real.
- Bartender: I got a call here for a Mister Doo? I got a call for Mister Doo.
- Melvin: [Stands up] Uh, Melvin Doo?
- Bartender: Nah. Scooby.
- Island Emissary: My employer would like you to solve a mystery on Spooky Island.
- Shaggy: Hold on, Man. We don't go anywhere with 'scary', 'spooky', 'haunted', or 'forbidden' in the title.
- Scooby Doo: Ror rydrocoronic.
- Shaggy: Right,or hydroclonic, but that's for a whole different reason, man.
- [Deleted scene]
- Daphne: [Chained up to a giant stone] you snuck up on me you jerk,let me out.
- Daphne: [giant mechanical arm head towards her] This can't be good. No,no,no
- [arm enters her body]
- Daphne: no,
- [arm pulling out her protoplasm]
- Daphne: NO!
- Daphne: [Protoplasm form] hey,give me back my spirit thingy. This is so uncool, and you're messing up my hair.
- Zarkos: [laughs]
- Daphne: [to Zarkos] You're a jerk, capital J E R
- [enters protoplasm vat]
- Shaggy: Gee, Scraps, you didn't have to freak out like a jerk and kill all humanity.
- Scrappy Doo: And I would have gotten away with it too if it wasn't for you meddling sons of...
- [door closes]
- Velma: Daphne? Are you okay?
- Daphne: I am so over this damsel in distress nonsense.
- Fred: Uh, where's Shagster?
- Shaggy: Like, I'm right here, man.
- Scooby Doo: Me too.
- Shaggy: Hey, Scoob, that was fun. Let's grab another skateboard and, like, do it again,man.
- Scooby Doo: Yeah.
- [laughs]
- Fred: This is more embarrassing than the time you started cleaning your beans at Don Knotts' Christmas party.
- Scooby Doo: Raggy, you're rhipped.
- Shaggy: I'm whipped? why don't you say that to my face, man?
- Scooby Doo: Rokay, I rill! Your rother eats rat roop!
- Shaggy: No, Scooby-Doo! YOUR mom eats cat poop!
- [Talking to Fred and Velma]
- Daphne: I'm a black-belt now. I've transformed my body into a dangerous weapon.
- Scrappy Doo: Scrappy-Dappy-Doo!
- Scooby Doo: Hey!
- Scrappy Doo: Ghosts don't stand a chance with me! Let me at em. I'll rock 'em and sock 'em.
- Fred: Scrappy, for the thousandth time, there's no such things as ghosts!
- Scrappy Doo: Sure there are, and when I find them I'll give them a good of puppy power!
- [Urinates on Daphne]
- Scrappy Doo: Ta-da!
- Daphne: Oh, God! He's peeing on me!
- Daphne: I'm looking for clues behind the strange behavior of the college students.
- Voodoo Maestro: Well, here's a clue for you: Purple is a fall color. It's the middle of May!
- Velma's Friend: [about Scrappy] "Puppy power", huh?
- Velma: [laughing] And he wasn't even a puppy. He had a gland disorder.
- Shaggy: Like chill out, Scooby-Doo, stop shaking.
- Scooby Doo: Me? That's you.
- Shaggy: Oh right it's me, sorry.
- Velma: What's the problem, exactly?
- Mondavarious: I believe somebody is casting a spell on the students. Now listen and look around. Can you notice any difference between those arriving and those departing?
- Daphne: They look like sober, well-behaved college kids.
- Mondavarious: Precisely. And they didn't before they came. They've changed. In other words, a magic spell.
- Mondavarious: Two years ago that little pest turns up at a casting session for our evil elves. Next thing i know i'm stuck in a hole and he's cavorting about in a mechanical version of me. But look thank you so much. What a delight. Fantastic! Fantastic!
