Headscratchers / Scooby-Doo! and the Reluctant Werewolf

• Why couldn't Wolfgong replace the wolfman for the Monster Road Rally, wasn't he a werewolf also?
  • Maybe in this Dracula's kingdom werewolves and wolfpeople aren't the same?
  • Another possibility is that Wolfgang doesn't know how to drive.
• Who was that voice telling them about the secret door next to the fireplace?
  • The monsters in this kingdom don't always get along, probably some ghost or monster that wasn't too happy with Drac at the moment. But then again Dracula wasn't that surprised that the gang made it to the party, so maybe he sent it.
• Why are they called the Hunch Bunch when there's just two of them?
  • It's possible there used to be more but we know Dracula is a Bad Boss. Or they prefer to have a rhyming name, regardless of accuracy.
• So Scooby Doo is okay with Shaggy having a girlfriend here (Googie) but not with Shaggy having Velma in Mystery Incorporated?
  • A. Googie never tried to change who Shaggy was, and B. Never tried to make him choose between her and Scooby.
• The second night of the full moon, Crunch and Brunch are heading into a grocery store and pass a woman, who comments "Honestly, the way these kids dress nowadays!" However, they're just wearing normal shoes, pants and striped shirts, nothing worth complaining about — the only unusual part of their outfits was Brunch's monocle, which is still a legitimate piece of corrective eyewear. So unless she was actually talking about their posture (the two being hunchbacks), what was her problem with the outfits?
