When does Milton the Monster return?

Milton the Monster is a Frankenstein-looking monster with a flat-topped, seemingly hollow head which emitted various quantities of white steam or smoke based on his mood or situation. Milton was created by mad scientist Professor Montgomery Weirdo and his assistant Count Kook, who lived in a haunted house on Horror Hill. Milton's voice, which was based on the southern accent used by Jim Nabors in his television role as Gomer Pyle, was provided by Bob McFadden. Other characters in the series included Fangenstein, a biker monster apparently inspired by Marlon Brando, Abercrombie the Zombie.
