Scrappy's pup excuses ("But what did you expect from a pup?", "I'm just a grwoing pup") were really funny. Generally, this must be the funniest episode of the show. And the Snake Demon was a cool villain.
I'm feeling like Velma is the only one solving these mysteries but this episode was cool! Scrappy is like a tiny dynomite, full of energy and trouble! Also it seems like Scooby and Shaggy are official members of the American Coward Association (ACA)!
