Ghost Highway
"Ghost Highway" On a stretch of seaside highway named "Route 99" (and the sign is in English too) is where the story takes place. A couple of strange accidents involving speeding trucks causes Tobor to come out to investigate and the episode begins with flashbacks of the accidents in his narration. An elderly couple were killed in an accident on Route 99 and while Tobor was out there two young people confronted him. They turned out to be the son and daughter of the deceased couple. After talking to Tobor they go off to look for clues and are soon surrounded by small black hooded creatures that have hand-weapons that look like the "sonic slicer" gun. The hooded creatures look more comical than scary and they make a weird sound.
