Russi Taylor, the voice of Phantasma from Scooby-Doo and the Ghoul School, has just passed away at 75 years old. She died on Friday in her home in Glendale, California. Taylor also voiced Hilda Brewski in "When You Witch Upon A Star" in The 13 Ghosts of Scooby-Doo, and the Owl Witch and Tiddlywink the Fairy from Scooby-Doo and the Goblin King. She was also very well-known as the voice of Minnie Mouse. RIP Russi!
