|This needs a stretch.|
The gang comes to warn a mad scientist about a mob of angry villagers who are coming after him.
Insert details here.
Then we have "Mad Science." It's nothing. It doesn't have reason to exist. The gang in flashback, mind you, investigates the villagers' claims of "things going too far." Once again, we have a completely harmless scheme with not a single ulterior motive requiring a call to the police--which is how Scooby-Doo, Where Are You? often ended. I'm not saying that Scooby-Doo needs to religiously stick to formula, but damn it, it has to provide drama; woefully lacking here.
