Headscratchers / The Scooby-Doo Show

• Why would a revolving restaurant have a fast setting?
  • Could be for when it's used with the European 50Hz power grid instead of the American 60Hz grid.

• Why did anyone even begin to think that the strange guy in period military garb hanging around the old fort in "Don't Go Near The Fortress Of Fear" was supernatural, in the first place? Usually the culprit who's executing a "Scooby-Doo" Hoax makes sure to incorporate something inexplicable - a holographic apparition, a boat that "vanishes" into a hidden canal, a faked "flight" via zipline, etc - to lend apparent support to the "ghost" theory. But the so-called "Ghost of Juan Carlos" never does a darned thing that would indicate he's a supernatural being, as opposed to just some lunatic who likes to set off cannons and cosplay an historical general.
