- A guy could get hurt around here. Come on. Let's go look somewhere else.

- Gee, Velma, I wish we had a clue to a clue.

- Don't worry, Daphne. If we stick around here, we're bound to find something.

- Wow! We almost got hit by that sandbag!

- Yeah! I guess the rope must have broke!

- Broke, nothing. Look. It's been cut with a knife, and ropes don't cut themselves.

- Let's look along here in the dressing room area.

- OK, Raggy.

- Hey, there should be a lot of junk in here to check over.

- Let's browse around here a bit, Scooby.

- Right.

- Hmm? Hmm? Should I look?

- What's with you, Scooby Doo?

- He's after me!

- He's after you?

- Yeah! Yeah!

- Aww! Ha ha ha! It's only a jack-in-the-box.
