The Mummy of Anka was in episode Scooby-Doo and A Mummy, Too. The mummy was really Dr. Najib. He wanted a scrab hidden inside of a hippo. Anka's appearance seems to based off of that of Kahris from the old universal horror movies. He made Stone Statues of some victims he captured so he can use the curse of Anka legend that everyone who looks on the mummy face will be transformed into stone statue.
