Synopsis:
The Challengers investigate Vaniki Island where Prof's friend King Tulaga has disappeared. The team is attacked by the islanders and taken to their stone god Seekeenakee. The Challengers discover that Seekeenakee is planning to invade a nearby island and eventually take over the entire South Pacific. The Challengers thwart the invasion plans and trick Seekeenakee into returning to Vaniki. Then they bomb the island, but the stone god escapes destruction by some unknown means.
