Justice League of America: The Silver Age #1

Aquaman is alerted that an alien starfish has landed on Earth, enlarged to giant-size three Terran starfish, and sent them off to help him conquer the world. Aquaman alerts the JLA, and they break up to take on the three starfish -- Green Lantern handling one, J'onn J'onzz and Wonder Woman handling the second, and Flash tackling the last. Flash finds that his starfish has taken control of the people of Happy Harbor, except for Snapper Carr. He deduces that it is the lime covering Snapper which makes him immune. Knowing the way to defeat their enemy, the heroes regroup to defeat Starro.
