Erotic action figures were a type of children’s toy in Ferengi culture. They were anatomically accurate representations of males and females of various species.
Nog owned a set of erotic action figures which included Vulcans, Humans, Klingons and Orions. In 2370 he sacrificed his collection to a group of hungry Horta in an attempt to try and slow their progress to Deep Space 9's core. He opted not to let the Hortas eat his Orion slave girl figure.
