A Drill Sqider is a species of monster resembling cephalopods, with four tentacles and four legs. Its prominent head features a spinning drill bit which serves two purposes: goring and dismembering its victims, as well as burrowing through the flesh of stomach monsters to inspect any of of their many webs for nourishment. Just below the drill is a spinneret to produce sticky strands of webbing for web-building as well as ensnaring prey.

A Drill Sqider's tendrils contain miniscule, rudimentary brains that function even once the tentacle is detached from the body - even as long as three weeks. When severed, the tentacles rely on touch to pursue whatever attacked them and constricts around its opponent's weak spot, such as their neck.

There are no known predators to this species of Sqider, nor of any Sqider.
