How to Find the Grubs in Deepnest in Hollow Knight

Team Cherry’s Metroidvania action-adventure game, Hollow Knight, follows the journey of a nameless warrior called the Knight as he travels through Hallownest, a now-ruined kingdom by a supernatural disease. As the Knight journeys through Hallownest, he will encounter various characters that will help fully unravel the story in the game. Some of these characters are cute little creatures called Grubs.

Grubs are small green creatures trapped inside glass jars that the Knight will find throughout Hallownest. These Grubs were trapped by a Void creature named The Collector, who loves to collect bugs that are both dead and alive all around Hallownest and preserve them in glass jars.

The Knight will know if there is a Grub nearby as its high-pitched crying can be heard in its general direction. Then, once the Knight finds one, the Knight can free them by striking the glass jar with the Nail to break it. After the Knight frees a Grub, it will do a little high-pitched shout of joy and burrow into the ground to return to its colony with the Grubfather.

There are a total of 46 Grubs all over Hallownest, and there are a few rewards for freeing a specific number of Grubs:

  • For the first four Grubs found, the Grubfather, found in the northwesternmost part of Deepnest, will reward the Knight with Geo (10 Geo for the first Grub, 20 Geo for the second, 30 Geo for the third, and 40 Geo for the fourth Grub found).
  • After freeing the fifth Grub, the Grubfather will reward the Knight with a Mask Shard.
  • After freeing the sixth to ninth Grubs, the Grubfather will reward the Knight with Geo (50 Geo for the sixth, 60 Geo for the seventh, 70 Geo for the eighth, and 80 Geo for the ninth Grub found).
  • After freeing the tenth Grub, the Grubfather will reward the Knight the Grubsong Charm, which allows the Knight to gain Soul when taking damage.
  • After freeing the 11th to 15th Grub, the Grubfather will reward the Knight with Geo (90 Geo for the 11th, 100 Geo for the 12th, 110 Geo for the 13th, 120 Geo for the 14th, and 130 Geo for the 15th Grub found).
  • After freeing the 16th Grub, the Grubfather will reward the Knight with a Rancid Egg.
  • After freeing the 17th to 22nd Grub, the Grubfather will reward the Knight with Geo (140 Geo for the 17th, 150 Geo for the 18th, 160 Geo for the 19th, 165 Geo for the 20th, 170 Geo for the 21st, and 180 Geo for the 22nd Grub found).
  • After freeing half (23) of the total Grubs, the Grubfather will reward the Knight with a Hallownest Seal, and the Grubfriend Achievement will be unlocked.
  • After freeing the 24th to 30th Grub, the Grubfather will reward the Knight with Geo (200 Geo for the 24th, 200 Geo for the 25th, 205 Geo for the 26th, 210 Geo for the 27th, 215 Geo for the 28th, 220 Geo for the 29th, and 220 Geo for the 30th Grub found).
  • After freeing the 31st Grub, the Grubfather will reward the Knight with a Pale Ore.
  • After freeing the 32nd to 37th Grub, the Grubfather will reward the Knight with Geo (230 Geo for the 32nd, 235 Geo for the 33rd, 240 Geo for the 34th, 245 Geo for the 35th, 250 Geo for the 36th, and 255 Geo for the 37th Grub found).
  • After freeing the 38th Grub, the Grubfather will reward the Knight with a King’s Idol.
  • After freeing the 39th to 45th Grub, the Grubfather will reward the Knight with Geo (260 Geo for the 39th, 265 Geo for the 40th, 270 Geo for the 41st, 280 Geo for the 42nd, 290 Geo for the 43rd, 295 Geo for the 44th, and 300 Geo for the 45th Grub found).
  • After freeing all of the Grubs around Hallownest, the Grubfather will reward the Knight the Grubberfly’s Elegy Charm, which allows the Knight to fire projectiles when attacking using the Nail and when at full health, and the Metamorphosis Achievement is unlocked.

Deepnest Grub 1

There are five Grubs in the Deepnest area. One can be found inside a hidden area in the southern part of Deepnest.

The Knight will encounter many enemies in Deepnest, but the Knight will specifically encounter the following enemies on the way to the first Grub: Garpedes and a Wandering Husk

Before the Knight can find the Grub that was mentioned, it is required that the Knight has the Mantis Claw ability, which allows the Knight to cling to walls and jump off of them, and the Mothwing Cloak ability, which allows the Knight to perform a horizontal dash forward, or the Monarch Wings ability, which allows the Knight to perform a secondary jump in mid-air. Additionally, the Knight must also purchase the Lumafly Lantern from Sly in Dirtmouth to light up very dark rooms. With these abilities, finding the first Grub in Deepnest will be no challenge.

To find the first Grub in Deepnest, this is what the Knight must do:

  1. Starting from the Bench inside the Tram in the southeast of Deepnest, exit the Tram, head to the left, and take the exit.
  2. The Knight is now in Deepnest and will be in a room that looks like a maze filled with Garpedes. Head slightly to the left, wait for the Garpede to pass through on the path above, quickly jump to the platform above, head to the right, then jump to the next platform above.
  3. Next, head to the left, wait for the Garpede above to pass through, quickly jump to the platform above, quickly run to the left, and drop down on the next path downwards.
  4. After that, head slightly to the left, wait for the Garpede below to pass through, quickly drop down, run to the right, and drop down on the next path downwards.
  5. Then, head to the left, jump across the spikes with the help of the Monarch Wings or the Mothwing Cloak ability, and take the exit on the left.
  6. Next, continue heading to the left, where the Knight will find a Bench next to a hot spring. Sit on the Bench to heal and save your progress, then stand in the hot spring to regenerate the Knight’s Soul. After that, continue heading to the left and take the exit.
  7. Then, head to the left, jump up the platform where the Knight will encounter a Wandering Husk, jump across the spikes on the floor and onto a small platform, jump across the spikes on the floor and onto the next small platform on the left, jump across the spikes and onto the ledge above on the left with the help of the Monarch Wings ability, strike the wall on the left (which is a breakable wall) several times to break it and reveal a hidden exit, then take the hidden exit.
  8. Finally, head to the left, drop down the gap, and at the bottom, the Knight will find a Grub trapped inside a glass jar! The Knight can now strike the glass jar to break it and free the Grub!
