The Grubfather is an elderly Grub[1] found in the north-west corner of the Forgotten Crossroads in a room full of small Grub dens; this room is referred to as the "Grubhome" in an official map. He will reward The Knight for each Grub found.

When first encountered, he will be crying as all the Grubs have been taken from their dens. When the Knight returns after freeing Grubs, the Grubfather will reward the Knight with Geo and other items according to how many Grubs have been saved.

There are 46 Grubs to be found in total. Rescuing 23 Grubs rewards the Grubfriend achievement, while rescuing the last Grub unlocks the Metamorphosis achievement.

After all Grubs have been rescued and rewards collected, returning to the Grubfather will reveal 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 of him.



Grubs are creatures found trapped in glass jars throughout Hallownest. When The Knight is close enough to their location, a faint crying noise can be heard in their general direction. They talk in high-pitched babbles and cannot be spoken to. When hit with the Dream Nail, their thoughts read "...Home...". They can be freed by breaking the jar with the Nail, after which the Grub will burrow into the ground and return to the Grubfather. Obtaining the Collector's Map after beating The Collector shows the locations of unfreed Grubs.



Rewards are based on the total number of grubs saved, not which grubs have been saved.

  • Occasionally the Knight will come across a Grub Mimic trapped in a glass jar that will transform and become hostile when freed. The easiest way to check is to Dream Nail them. Grubs will always say "...Home..." but Grub Mimics will say "...Kill...", "...Empty... " or "...Other...".
  • Upon receiving the final reward(s) from the Grubfather, if the Knight rests at a bench and returns, the Grubfather will have swallowed all of the Grubs and is lying engorged on the floor. The Grubs' babbling can still be heard from inside him, indicating they are alive.
    • It is unknown whether this is a cruel act on the Grubfather's part or just a part of Grub biology. The achievement earned after turning in all Grubs is called "Metamorphosis," and the charm references a "Grubberfly" - this may imply that the Grubs have entered a larval stage for a butterfly-like creature with the Grubfather acting like a cocoon.
