(and not "Yabba-Dabba-Doo!", presumably because of Fred Flintstone's use of that particular catchphrase). Yabba is voiced by Don Messick. Scooby-Dee is a female Great Dane, with white fur, first appearing in "The Scooby-Doo Show". She was a character in the episode titled "The Chiller Diller Movie Thriller", as a distant cousin of Scooby's, who helped them solve the mystery. She also has a cameo appearances in the second-season episode of "What's New, Scooby-Doo?", "Homeward Hound", where she is one of many dogs seen at the dog show the gang is attending. She is seen walking past the screen in two separate scenes in the beginning. Scooby-Dee was meant to return to "The Scooby-Doo Show" as a girlfriend to Scooby-Doo, but the show ended before that could happen. Scooby-Dee was voiced by Janet Waldo, better known to many viewers as the voice of Judy Jetson. In "The 13 Ghosts of Scooby-Doo", Vincent Van Ghoul is a renowned magician and warlock, with extensive knowledge of the supernatural. He is first visited by Shaggy, Scooby, Daphne and Scrappy with Flim-Flam, after they need some help with their plane, which has crash-landed in a nearby temple in Tibet. After Shaggy and Scooby unwittingly unleash thirteen terrible ghosts from the chest in which they were locked, Van Ghoul tells them that they must trap them again. "Why us?" a terrified Shaggy moans, to which Van Ghoul replies "Because you let them out!" Despite being very angry with the pair for unleashing the ghosts, he agrees to help them in their ghost-questing, and gives the group a crystal ball through which he can contact them. He shares personality traits with his voice actor, Vincent Price, like having a very morbid and dark sense of humour. In "Scooby-Doo! Mystery Incorporated", Van Ghoul is an actor who does horror films (much like Vincent Price, who was the inspiration for his character). He is constantly referenced and glimpses of his movies can be seen throughout the series (according to Shaggy he has done more than 400 movies). He makes a full appearance in the episode "Nightfright", when Shaggy and Scooby win an essay contest to have dinner with him, and later in the episode "Theater of Doom", where he directs the production of Crystal Cove's theatre stage of the legend of Friar Serra and his faithful donkey Porto, who supposedly saved many inhabitants from a tsunami that destroyed Crystal Cove.
