Baby Skeletons cause Toxic build-up and tend to attack in groups. Unlike most enemies, Baby Skeletons can infinitely respawn out of the flooded ground, regardless of whether the player has rested at a bonfire or not. Given their high humanity drop rate, this trait makes them good candidates for farming humanity. Furthermore, their AI combined with their small size and slow speed causes them to run into walls and group up, making farming easy. However, their drops usually vanish extremely quickly, making it paramount to pick them up immediately after killing them. They only seem to spawn while the player is inside the water or very close to it, right next to him.
The Baby Skeletons are able to dance with each other and form a circle if corralled into a specific spot by one of the pillars just before the second ramp underneath Nito's fog gate. It is unsure if all can be made to dance in this way but there has been records of a total of eight forming a dancing ring.
