Recycled from a story in issue #11. Characters last appearance until revived as "Frightenstein" in AC Comics.
There are several similarities between this story and the film "Little Shop of Horrors" (1960): carnivorous plant eats larger and larger life-forms, concluding with humans, and the image of its victim(s) appearing as the buds (or in the film, in the flowers) of the plant after they are consumed.
