The Monkees

Davy has been put under the spell of Lorelei, or to be precise, her magic necklace. Her uncle, a Transylvanian Count, wants to turn Davy into a vampire. When the other Monkees arrive looking for their missing mate from Manchester, Peter's mind is singled out to be put inside a monster and Micky to become a wolf man. Mike manages to escape the vampire's clutches by dressing up in a mummy's smelly old wrappings.
