YMMV / Scooby Doo Mystery Inc S 2 E 7 The Gathering Gloom

• The Un-Twist: Invoked. Evallo is so glaringly obviously the Graveyard Ghoul (complete with ACTUAL growling) that only Velma actually suspects him. The rest of the gang (except for Scooby as he's worried about Velma doing the case by herself) don't even consider him as a suspect and Sheriff Stone initially won't arrest him in case he's got the wrong man again. Everyone is flabbergasted when it turns out that he really is the Graveyard Ghoul.
