- I'm getting worried. We haven't seen hide nor long hair of Shaggy or Scooby.
- I hope they didn't run into that creepy ghost again.
- Look at the side of that hangar.
- Whatever it is, there's two of them this time.
- Don't just stand there. Let's get out of here.
- Look.
- They got scared of our shadows.
- Uh-oh. That's not you or me, Scooby.
- Boy, we're sure glad to see you guys. What'd you find out?
- We still don't have any clues as to what that ghost craft is that's flying around in the air.
- Or old Mr. Creepy who keeps popping up all over the place.
