How to Find the Grubs in Crystal Peak in Hollow Knight

Learn how to find the Grubs in Crystal Peak 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 kingdom ruined 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 dead and alive bugs 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 the Crystal Peak, 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 with the Grubsong Charm, allowing 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).

Crystal Peak Grub 1

A screenshot showing where to find a grub in Crystal Peak

There are seven Grubs in the Crystal Peak area. One can be found at the end of a maze of conveyor belts and spikes near the middle of the map of Crystal Peak.

The Knight will encounter lots of various enemies in the Crystal Peak. Still, the Knight will specifically encounter the following enemies on the way to the first Grub: Husk Miners and Glimbacks.

Before the Knight can find the Grub that was mentioned, it is required that the Knight must obtain the Mothwing Cloak ability, which allows the Knight to perform a horizontal dash forward, and the Mantis Claw ability, which allows the Knight to cling to walls and jump off of them. Finding the Grub in the Crystal Peak will be no challenge with these abilities.

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

From the bench at the bottom of Crystal Peak, head to the left and take the exit on the left.
In the next room, the Knight will encounter a Husk Miner. Head slightly to the left, head up the shaft using the Mantis Claw ability before the gap with the conveyor belts, head to the left again, and take the exit above.
Next, take the path on either the left, where the Knight will go up a level and encounter a Glimback, then head up the path above in the middle, where the Knight will encounter two Husk Miners and another Glimback that can be reached by using the Mantis Claw ability to cling to the wall on the left to ride the conveyor belt upwards then jump towards the next level, or take the path on the right where the Knight can use the Mantis Claw ability to cling to the wall on the right then jump towards the next level where the Knight will encounter a Husk Miner. Either way, take the path above on the right that leads upwards. It is worth noting that the path on the right requires the Knight to have the Monarch Wings ability or the double jump ability to reach and continue on the path.
After that, head to the left and, using the Mantis Claw ability, jump and cling on the conveyor belt on the shaft just before the end of the path to be carried up, dash to the right with the help of the Mothwing Cloak ability just before hitting the spikes at the top, cling to the conveyor belt on the right side of the shaft, dash to the left with the help of the Mothwing Cloak ability just before hitting the spikes at the top, cling to the conveyor belt on the left side of the shaft, and dash to the left with the help of the Mothwing Cloak ability just before hitting the spikes at the top towards the safe platform on the right.
Then, head to the right, jump and cling towards the conveyor belt on the right to be brought down slowly, dash to the left with the help of the Mothwing Cloak ability just before hitting the spikes at the bottom, cling to the conveyor belt on the left side of the shaft, dash to the right with the help of the Mothwing Cloak ability just before hitting the spikes at the bottom, hold the right movement button to pass through a slightly narrow path with spikes at the bottom and the top, then land on a safe platform below on the right.
Next, head to the right, jump and cling towards the conveyor belt on the right to be carried up, dash to the left with the help of the Mothwing Cloak ability just before hitting the spikes at the top, cling to the conveyor belt on the left side of the shaft, dash to the right with the help of the Mothwing Cloak ability just before hitting the spikes at the top, cling to the conveyor belt on the right side of the shaft, then jump towards the safe platform on the left.
Finally, head to the left and 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!

To exit this maze, the Knight can just strike the lever on the left side of the Grub to open the gate on the left of the lever.
