The Giant Turtle Man!
Story featuring Jimmy Olsen
Storyline: Jimmy finds an enlarging ray-gun and accidentally fires it through a turtle, striking himself, turning him into a giant turtle-man. When Jimmy begins to collect tons of steel objects, dumping them in an island volcano, Superman is called out to stop him. But Lori Lemaris tells Superman that an Atlantean criminal created the ray-gun and controlled Jimmy telepathically as part of a plan to protect pirate treasure buried on the volcanic island. Superman restores Jimmy with Brainiac's shrinking ray and recovers the pirate loot.
