Forbidden Worlds #79 (1959)

Dr. Crager, a disgraced scientist, reunites with his long-lost cousin Professor Doyle, a former math prodigy now performing with a trained ape named Jocko. With Doyle’s genius and Jocko’s unexpected aptitude, Crager prepares to launch his photon ship toward Noxis—a planet he believes holds advanced human-like life—on a journey that could either revolutionize space travel or lead to a devastating conquest.

On a remote Pacific island discovered during a government mapping mission, the crew of the *Sprite* stumbles upon a ruined temple and a mysterious woman named Lelia, who speaks fluent English despite the island’s apparent isolation. As the crew investigates a glowing diamond in the volcano’s crater, the skipper Adams becomes obsessed with claiming the treasure for himself, setting in motion a plan to abandon his crew and vanish with the fortune.

Uncle Hoober, a sprightly seventy-five-year-old with a childlike obsession for cereal premiums, spends his days collecting bizarre gadgets from breakfast food boxes—especially a mysterious teleporter he’s convinced can send objects across space. When the device finally works, sending his chair hurtling into the cosmos, his nephew Hector and wife Mona are left stunned, torn between disbelief and the terrifying possibility that the old man’s whimsy might be something far stranger.
