The crew of the research vessel, the Calico at one point rescue Godzooky (voice of Don Messick), the young offspring of the mighty giant monster, Godzilla (voice of Doug Wildey). Apparently, a pact was made that if the crew took care of the little guy, Godzilla would help if they needed him. As it turns out, this was a most fortuitous thing, because in the voyages of the Calico, they investigate mysteries that all too often lead to run-ins with dangerous giant beasts. With no way to battle the beasts themselves, the crew, either through a special signaling device or Godzooky calling himself, can summon Godzilla seemingly from anywhere around the world to confront the menace at hand.
