Scooby-Doo 2: Monsters Unleashed
- Smart Scooby: Hush now, buffoon. This is a highly combustable synthesis.
- Tough Shaggy: What?
- Smart Scooby: I'm going to transform us back!
- Tough Shaggy: No way, geek! I wanna stay like this forever! (throws Formula into the wall)
- Smart Scooby: NO!
- Shaggy: (after being transformed into a woman) I've got a chick's body!
- Scooby: (turns into the Tasmanian Devil) I'm the Tasmanian Devil!
- Shaggy: The only time we've done something right is when we accidentally plowed into the Snow Ghost, because we accidentally glued our feet to rocket-powered roller skates.
- Scooby: Yeah, eight stupid times.
- Shaggy: Let's face it Scoob. We'll never anymore than our old goofy selves. (sad) I wish once, just once, I could do the right thing on purpose. You know Scoob, like be a hero, and save the day. But who are we kidding, right? (throws rock into lake)
- Velma:(hands Shaggy the control panel) Here Shaggy take this.
- Shaggy: Why are you giving this to me (hands it back to her)
- Velma: (hands it back to Shaggy) I'll distract those skeleton screw balls, you and Scooby get this to the Monster Hive.
- Shaggy: Us? (looks at Scooby)
- Velma: Yes, you're faster than me. Once there just plug it into the base. (points to a button on the control panel) Push this button, I fixed it so it'll destroy all the monsters.
- Shaggy: (slides down a wall) But, but we can't.
- Scooby: (upset) We're screw ups.
- Shaggy: I mean we tried being heroes like you guys, but we're not okay? We're just not.
- Velma: Like me? (kneels next to Shaggy) That's funny. I've always wanted to be like you guys. (Shaggy amd Scooby look at each other in confusion) You guys are so free. You're never afraid to be who you really are. Whether you're fearful, or joyful, or...hungry. I think you've been heroes all along. You just haven't known it.
- The Cotten Candy Glob: (after Shaggy and Scooby jumps on him and eats him) No! I'll give you cavities!
