- Base-Breaking Character: The Boo Brothers themselves. They're either funny or annoying in a movie where some feel they don't belong in, since they're among the only confirmed ghosts in the movie.
- Big-Lipped Alligator Moment:
- The movie starts with one; a ghost scares Scooby, Shaggy, and Scrappy out of their home, and then sings about how, scary though she is, she's terrified of the Boo Brothers. When the Boo Brothers actually appear, they don't exactly live up to that impressive hype.
- The Colonel's ghost suddenly hainvg a steamroller in the tunnels as he chases them.
- Ensemble Dark Horse: Sadie Mae Scroggins has some fans out there that totally adore her.
- First Installment Wins: Zigzagged, of the three 1980's animated Scooby Doo films, this is well-remembered and was the one with the highest critical praise (being one of the best reviewed Scooby Doo movies of any era on IMDB and Rotten Tomatoes), but the second film, Scooby-Doo and the Ghoul School is considered more iconic and is probably better remembered today.
- Jerkass Woobie: Farquard the butler. He's fairly unpleasant to the Scooby gang, shows no concern for their well being, and seems just a bit unhinged. Still, if you served someone for more than 60 years and your reward was to continue your service, this time to someone you've never even met, you'd probably be hacked off a bit too.
- Older than You Think: Like the better known Scooby-Doo on Zombie Island a decade later, this movie made good use of the combination of the regular "Scooby-Doo" Hoax and real ghosts (about in a much lighter and goofier combination).
- Rescued from the Scrappy Heap: Scrappy-Doo is significantly more bearable in this movie, since he's a lot less brash and needed to solve the riddles until Shaggy gets enough of a clear head to figure out the last few.
- Retroactive Recognition: Shreako is voiced by Rob Paulsen, years before he'd go on to be one of the most prolific voice actors in the world.
YMMV / Scooby-Doo Meets the Boo Brothers
