This hideous sea monstrosity combines the most ferocious features of simian and carp, its fish-like tail sprouting a grotesquely primitive humanoid torso, head, and limbs. Although little more than 2 feet long, the nasty thing gibbers wildly as it gnashes its curling fangs and swipes at prey with webbed claws.
Speed 20 ft., swim 40 ft.
A ningyo has a +2 racial bonus on combat maneuver checks. When two or more ningyos are grappling the same creature, each gains a +1 bonus on grapple combat maneuver checks and a +1 bonus on grapple damage rolls.
The body of a ningyo never rests peacefully. Every night, an hour after sundown, an intact ningyo corpse animates; its type changes to undead (aquatic), and it gains undead immunities, bonus hit points based on its Charisma instead of Constitution, and the startle ability. At dawn, the undead ningyo becomes a corpse again. An undead ningyo knows when the dawn is coming and attempts to find shelter so it is not discovered as a corpse. A ningyo missing a limb, head, or tail does not animate at night, but can do so if reunited with its missing body part. A ningyo corpse that is burned or torn apart and its pieces scattered does not rise as an undead.
Any creature that bites a ningyo or swallows any part of it becomes poisoned.
If an undead ningyo attacks in the surprise round, its target must attempt a DC 11 Will save. Success means the target is shaken for 1 round; failure means it is frightened for 1d4 rounds. The target can only be affected by that ningyo’s startle once every 24 hours. Creatures with 6 or more Hit Dice are immune to this ability. This is a mind-affecting fear effect. The save DC is Charisma-based.
Up to two ningyos can share the same square at the same time. If two ningyos in the same square attack the same foe, they are considered to be flanking that foe as if they were in two opposite squares.
Environment warm oceans
Organization solitary, pair, or shoal (3–22)
The bane of fishermen and divers, ningyos lurk in tropical waters, gorging themselves on fish and attacking anything they can sink their tiny fangs into. Primitive, miniature mer-monsters, ningyos are frightening bogeymen of the sea, often attacking seagoers, ships, and fishing tackle out of blind hunger. These terrors swarm by night and can easily drag opponents down to drown amid a swarm of claws and needling teeth.
A slain ningyo always returns to life by night, adopting old habits or searching for its killer, and reverting to a corpse at dawn. Sometimes its corpse washes up on shore as a gruesome and fascinating curiosity, animating the next night to attack its would-be collector.
A ningyo measures approximately 2 to 2-1/2 feet long from head to tail, and weighs 6 to 9 pounds.
