How to Find Mister Mushroom in Deepnest

Team Cherry’s Metroidvania action-adventure game, Hollow Knight, follows the journey of a nameless warrior called the Knight as he travels through Hallownest which is now a kingdom in ruins because of a supernatural disease. As the Knight journeys through Hallownest, he will encounter various characters that will help fully unravel the story in the game. One of these characters is a talking mushroom named Mister Mushroom.

Mister Mushroom, who will appear after the Knight has defeated all three Dreamers, can be heard babbling from a distance and will speak gibberish once the Knight finds him and talks to him. In order to understand what Mister Mushroom is saying, the Knight must first equip the Spore Shroom Charm, head back to Mister Mushroom, and talk to him. This must be done before Mister Mushroom leaves and goes to a different location.

After finding Mister Mushroom all throughout Hollownest, a secret cutscene will be unlocked after beating the game.

To get a hint of Mister Mushroom’s locations, there is a glowing glyph called Riddle Tablet found inside a secret room in the southeastern part of Deepnest that, if the Knight reads it with the Spore Shroom Charm equipped, will give clues as to where the Knight can find Mister Mushroom, who the Riddle Tablet refers to as Master Herald. But, to save you some time trying to solve the riddles of the Riddle Tablet (and you are also reading a guide about it anyway), it would be better to tell you where the Knight can find Mister Mushroom: in Fungal Wastes, in Kingdom’s Edge, in Deepnest, in Howling Cliffs, in Ancient Basin, in Fog Canyon, and in King’s Pass.

In this guide, the player will learn how to find Mister Mushroom in Deepnest!

Deepnest

As mentioned above, before the Knight can find Mister Mushroom in Deepnest, the Knight must first defeat all three Dreamers, found in the Teacher’s Archives in Fog Canyon, in the Watcher’s Spire in the City of Tears, and in the Beast’s Den in Deepnest, and found Mister Mushroom in Fungal Wastes and Kingdom’s Edge.

The third location where the Knight can find Mister Mushroom is in Deepnest and Mister Mushroom can be found in the bottom left corner of a room near the middle of Deepnest.

The Knight will encounter lots of various enemies in Deepnest but the Knight will specifically encounter the following enemies on the way to Mister Mushroom: Garpedes, Wandering Husks, Husk Hornheads, Deephunters, Husk Bullies, and Galien, who is a Warrior Dream boss. Fortunately, however, the Knight does not have to defeat Galien to find Mister Mushroom in the area.

Before the Knight can find Mister Mushroom in the area, 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 forwards. Additionally, the Knight must also purchase the Lumafly Lantern from Sly in Dirtmouth in order to light up very dark rooms. Although not required, it would help if the Knight has the Monarch Wings ability, which allows the Knight to perform a double jump in mid-air. With this item and these abilities, finding Mister Mushroom in Deepnest will be no challenge at all.

In order to find Mister Mushroom 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 and is 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, quickly 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 ability or the Mothwing Cloak ability, then 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 up the small platform above the spikes, jump up the platform above on the right where the Knight will encounter a Husk Hornhead, head to the path on the right, then jump up the next platform at the end of the path where the Knight will encounter a Deephunter.
8. After that, head to the left, head up the wall on the left with the help of the Mantis Claw ability where the Knight will encounter another Husk Hornhead and another Deephunter, head to the left where the Knight will encounter a Husk Bully and another Deephunter above on the ceiling, at the end of the path head up the shaft with the help of the Mantis Claw ability, then take the exit on the left at the top.
9. Next, head to the left, drop down three gaps, drop down the next gap and dash to the path on the left with the help of the Mothwing Cloak ability so that the Knight will fall on the spikes below (be careful not to hit the spikes above the path), head to the left, jump and dash with the help of the Mothwing Cloak ability towards the platform above on the left, drop down the platform, jump across the spikes, head to the left where the Knight will encounter another Deephunter, with the help of the Mantis Claw ability head up the wall on the left of the big opening of where the Deephunter was found, head to the right where the Knight will encounter two Husk Bullies and another Husk Hornhead, head up the next shaft with the help of the Mantis Claw ability, head to the right, then take the next exit above.
10. Then, head to the left, jump across the spikes and towards the wall on the left, head up the wall with the help of the Mantis Claw ability where the Knight will encounter two separate Deephunters, then at the top take the exit on the left.
11. After that, head to the left, jump across the gap, drop down the platforms, jump up the next platform to continue heading to the left where the Knight will find the corpse of Galien, who is a Warrior Dream boss, and, at the end of the path, the Knight will find Mister Mushroom!

 As mentioned above, the Knight should have the Spore Shroom charm equipped otherwise Mister Mushroom will speak gibberish.

Now that the Knight has found Mister Mushroom’s third location, the Knight can now strike him once so that he will face forwards and talk to him. It will seem like Mister Mushroom is talking to someone else or himself and will not acknowledge the Knight.

After that, Mister Mushroom will leave and proceed to his next location which is in Deepnest! The Knight is now one step closer to unlocking a secret cutscene!
