A new species of undersea creature is discovered, and Batman joins the expedition to bring it back alive. One member of the group, Devoe, is sabotaging the mission and trying to kill the creature. Batman stops him and exposes his plan to kill the creature and steal its egg. Devoe planned to keep the egg and become rich as the sole owner of the new species. Batman recovers the egg and takes the creature alive. As a reward, Batman is given the egg to display in the Bat-Cave, knowing it will take a hundred years to hatch.
