TheAtomicLight added the category called Happy Haloween characters to the Red Herring page!
You can read about it on his page
I'm confused myself
Who’s Red Herring? I didn’t see him in the movie..
He made a CAMEO - a short appereance. Maybe he was one of the people in the crowd or something (I don't know because I did not watch it, I will try finding him when I find the movie)
Red Herring from APNSD
A Pup Named Scooby Doo
I heard Velma say “And That’s How We Got A Pup Named Scooby-Doo!” during a interview, I just thought of it lol @Okraila
What do you think?
