Lemur (FFIII)

An undead monster that appeared in Hein's Castle, located in a world far away. They are souls of the dead who have been entrapped by evil, and hold an eerie form of a single eye floating in air. They wander inside Hein's Castle in search of intruders, but they don't use any special attacks. Hence, they aren't much of a threat, but they do bring with them allies, so it is well advised to face them without letting your guards down.
