Prison Depths (spawned by Hammer)
A smaller, faster flying version of Buzzcutters, these are only spawned by other monsters.
While Purulent Zombies only spawn a group of them once upon death, Hammers can spawn many groups of them at once if the player moves away from them, and they do not despawn upon the death of the Hammer which released them.
