Scooby-Doo Meets the Boo Brothers (1987)
I’ve always like this. The creepy old mansion, the treasure hunt, the secret passageways.
I’ve never been a Scrappy-Doo hater; but then again, this for the most part was my only exposure to him. Maybe I would be if I had grown up on the original Scooby-Doo Where Are You first and then transitioned into Scrappy-Doo.
The background music for this is quite odd, though I don’t really have any other old-school Scrappy-Doo fresh in my head right now so I can’t say if the soundtracks were always that…eclectic?
When I a “young’n” and saw the dancing pants for the first time I thought it was the funniest thing ever.
