Swarm of Sarcopikes

Medium Swarm of Tiny monstrosities, Neutral Evil
DDB

Sarcopikes are fishlike creatures that swim in the freshwater streams, ponds, and lakes of the Shadowfell.
In places where the barrier between the Shadowfell and the Material Plane is weak, a school of sarcopikes (known colloquially as a sarcopile) might cross over and terrorize locals. The schools lurk in water sources that abut cemeteries, battlefields, or other locations abundant with fresh corpses for them to eat.
