The Grubfather is the ageing patriarch of a colony of Grubs who make their home in a room in the Forgotten Crossroads. Grubs are harmless creatures who have a good sense of direction and are highly skilled tunnelers. They are known to collect shiny things in their burrows, such as Geo and Relics.
When the Grubfather is first encountered, he is crying as all the Grubs have been taken from their dens. When returning after freeing Grubs, the Grubfather grants rewards such as Geo and other items according to how many Grubs have been saved.
After all Grubs have been rescued and the rewards collected, returning to the Grubfather reveals that all the Grubs are gone from their holes, and the Grubfather is now laying in the centre of the room, his stomach extremely bloated. The muffled noises of Grub chatter can be heard from inside him. This appears to be part of the life cycle of Grubs where they will metamorphose into a Grubberfly.

- The Grubfather is one of the few NPCs who can be "hit" with the Nail without taking damage.
