Let's go back to Tokyo Disneyland's Toontown and look at the rest of it's Halloween decorations. The gazebo/bandstand has two ghosts on it's roof....one wearing orange Mickey ears and another wearing an orange Donald Duck sailor cap. Note the umbrellas over the tables that are all changed just for the season.
Tokyo Disneyland places cast members dressed as witches in both Toontown and in Fantasyland. They pass out candy to park guests, but first you need to tell them "Trick or Treat."
