Nerveworm

Nerveworms are long worms that live in the gelatinous slime under the external membrane of the Single-cell Mountain. They glow a bright white, and tend to be seen looming in the darkness before they reach their prey.

Nerveworms are hostile, erupting from the ground and breaking the mountain's membrane as if it were nothing. They attempt to spear prey and drag it down into the hole in the membrane they have created for consumption.

They are more active during the night, but this is not a guarantee of safety during the day.
