Shaggy: Oh boy, maybe I shouldn't have taken this new job.
Scrappy Doo: Don't be silly Shaggy, you'll make a great gym teacher, and I'll make a great assistant, See? I've been working out. [picks up a barbell but falls so that the barbell is stuck between the back doors of the van]
Shaggy: Zoinks! He's not only working out, he's falling out!
Scrappy Doo: [Still hanging onto the barbell] Whee! I bet this is great for building up my shoulder muscles.
Shaggy: What's the rush? We've got 1400 hours, that's a lot of time.
Scooby Doo: [snatches the fungus fudge from Shaggy] Yeah! A lot!
Scrappy Doo: But Shaggy, 1400 hours means 2:00, we've only got an hour!
Shaggy: Like why didn't you say so, Scrappy? Don't just stand there! Come on it's time to warm up.
Colonel Calloway: [trying some fudge] Doesn't it taste a little... moldy?
Ms. Grimwood: Of course, Colonel, fungus fudge always tastes moldy.
Colonel Calloway: Fungus fudge? [Drops the fudge so that Matches catches and eats it, and then drinks down a cup of tea]
Ms. Grimwood: Yes, it goes so well with toad stool tea.
Colonel Calloway: Toad stool tea? [Drops the teacup on Matches]
Scrappy Doo: But Shaggy, why do we have to wear a tutu?
Shaggy: Because uh... uh... well...
Ms. Grimwood: Because ballet makes my girls limber.
Shaggy: Yeah, that's it, limber.
Revolta: It's been too long since we had company, Creeper.
Grim Creeper: I knew you'd be pleased, Revolta.
Revolta: Yes, because these 5 will remain here permanently. [Sinister laughing]
Grim Creeper: But, Revolta, what happens when your spell wears off?
Revolta: Don't upset yourself, Creeper. I'm preparing a spell to make them evil forever. At the stroke of midnight, I'm going to revoltize them.
Grim Creeper: Revoltize them? Oh, how revolting.
Revolta: Yes, isn't it though? (Snarls) Now stop cringing, and put those girls to work!
Grim Creeper: Yes, Revolta!
Scrappy Doo: So with the cadets it was a snap to escape Revolta's trap, now let's get loose and dance and clap while I lay on my Scrappy rap. Over there is Daddy Drac who's glad to have his daughter back, and all the guys from Calloway are here to dance the night away. And there's Miss G with Colonel C, grooving to my melody.
Ms. Grimwood: Your boys were very gallant to go after my girls.
Scrappy Doo: And Grunt's with Elsa Frankenteen who wants to be a slam dance queen, and Phanty really does her thing, a dance for two, the Phanty fling.
Scooby Doo: Raggy, reyes, reyes.
Shaggy: Rice, where?
Scooby Doo: [Widens one of his eyes with his paws to tell Shaggy about the plants growing eyes] Ro, reyes!
Shaggy: Oh, eyes, why didn't you say so?
Scooby Doo: Ri rid.
Scooby Doo: Raggy, rats, rats!
Shaggy: Rats? [yawns and gives Scooby mouse traps] Like take 2 of these and call me in the morning.
Scooby Doo: Ro Raggy, RATS.
Shaggy: Bats? [on hearing Scooby telling him about the bats, looks at the shade] See, Scoob? There's nothing shady about the shade, now go onto sleep.
Shaggy: That's keeping your cape in shape, Sibella.
Sibella Dracula: Fangs a lot, Shaggy.
Tanis the Mummy: And I'm keeping my tape in shape.
Ms. Grimwood: You certainly are, Tanis, scaerobics are good for everyone.
Daddy Dracula: [about Shaggy and Scooby] Sibella, these two are even battier than ve are!
Sibella Dracula: They are a little strange, Daddy, but they're fangtastic teachers!
