Editing Menace of the Manticore/Transcript (Toonwriter)

(Angel Dynamite enters the Mr. E's lair)
Angel: The Mystery, Inc. kids have found a piece of the Planispheric Disk.
Mr. E: So now, we know where 2 of the pieces are. Good work, Angel.
Angel: Just remember, I'm working with you, not for you, E. I'm worried about those kids.
Mr. E: Why?
Angel: Pericles is loose, and that nutso parrot might go after the piece, which puts them in danger, and us, if the former members of our club get wind of it.
Mr. E: Don't worry, little Angel. The other 2 won't move a muscle as long as Fred Jones is still alive.
Daphne: Look at that! Are Manticores double-jointed?
Velma: This is no Manticore, Daphne. This is... (unmasks the Manticore)
Scooby, Shaggy, Daphne and Fred: Hot Dog Water?
Velma: Just as I suspected. It totally makes sense when you put the clues together. Someone with computer skills had to make that fake website, and Hot Dog Water has those skills. And remember, just before the Manticore attacked, I smelled something familiar. It was briny, greasy hot dog water. (to Hot Dog Water) But what I don't know is why Shaggy and Scooby had such high voices after you attacked them before, or why you'd want this amusement park to close so badly.
Hot Dog Water: How could you know? Your intellect is so far inferior to mine. (takes off the Manticore's outfit) It all started on a boring Friday night when I didn't have a date.
Velma: Hard to imagine.
Hot Dog Water: I decided to run some experiments on the steel used to build the park's rides. I found that if you melted the steel down and combined it with chromium, stalagmite, and mercury phosphate, it created a kind of super helium. Shaggy and Scooby must have inhaled some helium gas from the Manticore's posterior relief hole. That's why their voices were so high. I figured if I could get the park to close, I could take all the steel, melt it down, and sell the super helium to the Australian zeppelin fleet. I'd have made a fortune and shown you up in the process, Velma.
(Sheriff arrests Hot Dog Water)
Daphne: Another mystery solved.
Fred: It still seems like something's missing.
(The Fortune Telling Machine prints the fortune)
Hot Dog Water: (reads) "Meddling kids and their dog will foil your plan".
Fred: Yep. That would be it.
(Sheriff drives away)
Angel: I know who has the Planispheric Disk piece, but not where.
Mr. E: Speak.
Angel: I put a bug on Velma when I saw her earlier. She didn't suspect a thing. Later, I heard Fred tell her that Shaggy and Scooby have the piece. But he didn't say anything more than that.
Mr. E: He told Velma and us enough. Everything will work out just fine. You see, Scooby is a far more trusting companion than Pericles was to me.
