Floating eyes are strange fish that live in a symbiotic relationship with other predatory sea creatures. They have transparent bodies, showing their bones, teeth, and internal organs plainly; most prominent is the creature’s single 3-inch-diameter eye, which comprises over 90 percent of the creature’s body mass.

Any living creature meeting the gaze of a floating eye must roll a saving throw vs. Paralyze or become dazed and immobile. The fish must maintain eye contact to control the victim, who will recover in just 1d4 rounds after eye contact is lost. While the victim is immobilized, whatever predatory fish are partnered with the floating eye will move in and attack, and after all victims are slain or have fled the floating eye is free to eat the leftovers of any kills.
