 The toyline was conceived and marketed by Remco on television during the early 1960s, inspired by the giant insect (see List of natural horror films) genre that were popular from the 1950s, that were in reruns on TV.A child could propel the giant insect toys via pull-string motors towards blue soldiers while counter-attacking with heavy motorized artillery and helicopters.Remco also produced a bug-eyed helmet and grenade pistol which the child could wear for total immersion in the play-acting scenario.
