Hypnotism: Any creature gazing upon a floating eye must make a Will saving throw (DC 10) or become fascinated by the visible eye's patterning, effectively paralyzed, until the fish moves out of sight. This special ability is not consciously used by the fish - it is both used for defense (stupefying predators if they get too close) and for hunting (paralyzing small marine creatures to be eaten). The fish cannot turn the power on and off, and does not possess the capacity to use it intelligently against potential foes.

Floating eyes can sink to the ocean floor, and bury themselves in the debris there, effectively gaining a +10 Hide bonus.

Floating eyes have no attack form, but gazing upon their eye can incite hypnosis in the form of a paralyzed stupor.

The Floating Eye first appeared in the Monster Manual (Gary Gygax, 1977).
