Space Amoeba

After a space probe unexpectedly crashes on a remote Pacific atoll, the alien stowaways aboard hatch a plan to conquer their new environment by infecting its inhabitants. They quickly attach themselves to three local creatures—a squid, a crab, and a snapping turtle—transforming them into enormous, terrifying mutants. As these colossal monsters emerge, chaos ensues on the atoll, setting the stage for a battle between the transformed beasts and the natural order of their world.
