Mister Mushroom | Hollow Knight Wiki

Mister Mushroom is an NPC in Hollow Knight. He will start appearing in various locations after defeating the three Dreamers.

Mister Mushroom Information

Mister Mushroom is a mysterious entity first located in the Fungal Wastes and part of the mushroom "Hivemind". This can be seen as he seems to be talking to other entities including the Hungry Knight, a character for an eponymous Team Cherry game. He is also known as the Herald or Master Herald.

• Location: You will find Mister Mushroom standing right where Cornifer used to sell his map in the Fungal Wastes after defeating the three Dreamers.
• Progression: To trigger the quest start, you need to equip the Spore Shroom Charm before talking to him. If you interact with him without it, you won't understand what he's saying – only gibberish – and the quest won't progress.
• Combat: Cannot kill Mister Mushroom.
• Rewards: Allows the player to get the secret achievement "Passing of the Age" as well as an extra scene at the end of the game.

 Passing of the age achievement

In order to get the achievement, you need to interact with Mister mushroom in the following locations :

1. In the Fungal Wastes, where Cornifer sells his map and after the three dreamers are Dreamnailed.
2. In Kingdom's Edge. In a Small Cave on the middle left of the tall area between the tram station and the main area.
3. In Deepnest. In the bottom left corner of the rectangular room bellow the failed tramway.
4. In the Howling Cliffs. Inside of nailmaster Mato's house.
5. In the Ancient Basin. In room just after the broken vessel fight.
6. In the Fog Canyon. in the left side of the rectangular room just below the overgrown mound.
7. In the Kings Pass, exactly where the Knight starts the game.

Following this, getting any ending will add a secret scene as well as giving you the 'Passing of the Age" achievement.
