LOCATION CHECKLIST
Check off rescued Grubs, then use Missing and a region to find what is left. The numbers in Recommended Order are only a suggested route, not an in-game rescue order or reward order.
STILL TO RESCUE

GRUBFATHER
Rewards depend on how many Grubs you have rescued, not which jar you broke. Rescuing a Grub does not collect the reward. Return to the Grubfather in the northwest Forgotten Crossroads, then mark the reward claimed here.
One of 16 Mask Shards. Four shards make a mask that scores 1%. Return to the Grubfather to collect it.
Charm reward. Marks Grubsong on the Charms checklist and adds 1% toward 112%.
A collectible egg. It does not add 112%.
A relic for Lemm. Rescuing 23 Grubs also meets the Grubfriend achievement condition in-game.
One of six Pale Ore. The ore itself does not score; Nail upgrades that spend it do.
A relic for Lemm. It does not add 112%.
Final Charm reward. Rescuing 46 does not mark this Charm until you collect it from the Grubfather.
CLEANUP
When a few jars are left, use Missing and a region on the checklist above. Unrescued Grubs also make a faint crying sound in nearby rooms. The last three are behind the Love Key.
| Tool | How to use it |
|---|---|
| Collector's Map | The Love Key is at the Traitor's Child grave in the Queen's Gardens, after Traitor Lord. It opens the Tower of Love in the eastern City of Tears. Beat The Collector for the map; unrescued Grubs then appear on area maps you have bought from Cornifer or Iselda. |
| Region filter | Match those map pins to the region list on this page. One Waterways jar is entered from Kingdom's Edge, not from the main Waterways. |
| Ability requirements | Tick Mantis Claw, Crystal Heart, and the rest under Abilities you have to hide jars you cannot reach yet. |
| Missing only | Hide rescued Grubs so only open jars remain. |
| Mimics | Crystal Peak (near Cornifer) and Deepnest (west of the Hot Spring) have Grub Mimics. Dream Nail a jar: a real Grub thinks “...Home...”. |
WHAT SCORES
Saving a Grub adds 0% to World Sense. The Charm rewards do, and only after you collect them from the Grubfather. Checking Grubsong or Grubberfly's Elegy here also marks them on the Hollow Knight Charms Checklist and the Hollow Knight 112% Completion Checklist.
| Rescued | Reward | Toward 112% |
|---|---|---|
| 5 | Mask Shard | No. Four shards make one mask point. |
| 10 | Grubsong | 1% after you claim the Charm. |
| 16 | Rancid Egg | No. |
| 23 | Hallownest Seal | No. Grubfriend condition is met in-game. |
| 31 | Pale Ore | No. Nail upgrades that spend ore do score. |
| 38 | King's Idol | No. |
| 46 | Grubberfly's Elegy | 1% after you claim the Charm. |
Other rescue counts pay Geo. City of Tears includes the three Tower of Love jars, which need the Love Key.

| Greenpath | 4 |
| Fungal Wastes | 2 |
| City of Tears | 8 |

GOOD TO KNOW
Counts, rewards, the Love Key, achievements, 112%, and saves.
There are 46 Grubs. Rescuing them does not add a point each. Use this checklist to mark the jars you have broken and to find the ones still missing.
No. Grubs add 0%. Grubsong at 10 Grubs and Grubberfly's Elegy at 46 each add 1% after you collect them from the Grubfather. Pale Ore at 31 Grubs is spent on Nail upgrades, which do score. Track those Charms on the Hollow Knight Charms Checklist.
Rewards are based on how many Grubs you have rescued, not which jar you broke. Special rewards are a Mask Shard at 5, Grubsong at 10, a Rancid Egg at 16, a Hallownest Seal at 23, Pale Ore at 31, a King's Idol at 38, and Grubberfly's Elegy at 46. Other counts pay Geo. Mark a reward claimed only after you talk to the Grubfather.
Beat The Collector in the Tower of Love for the Collector's Map, which marks unrescued Grubs on maps you have bought from Cornifer or Iselda. Then use Missing and a region on this page. Crystal Peak and Deepnest have Grub Mimics; Dream Nail a jar if you are unsure.
The Love Key is in the Queen's Gardens, at the Traitor's Child grave after Traitor Lord. It opens the Tower of Love in the eastern City of Tears. The Collector there holds three Grubs and drops the Collector's Map.
No. Rescuing 23 Grubs meets the requirement for Grubfriend, and rescuing all 46 meets the requirement for Metamorphosis. Your Steam or console platform records the achievement separately.
