Silksong’s Passing of the Age: How I Found Every Mister Mushroom Location
Passing of the Age quest in Hollow Knight: Silksong guides players step-by-step to secret endings and achievements.
I still remember the exact moment I stumbled into the Passing of the Age quest in Hollow Knight: Silksong. I was deep in the Putrified Ducts, roaming east of Fleatopia, when a faint golden glow caught my eye. At first I thought it was just another piece of environmental polish, but no—Hornet had found something much stranger. If you're like me and you want that secret ending and achievement, this guide will walk you through my own journey, step by step.
How I Triggered the Passing of the Age Quest
The trigger is shockingly easy to miss. From Fleatopia, I kept heading east until I found a route going upward. Wall jump was enough to reach a cliff, but when I looked up, there it was: a golden glow above me. I used the Silk Soar ability to enter the hidden opening. At the end of that tunnel, Hornet can inspect a golden tablet. The game asks if you want to promise the wish. Say yes, and the Passing of the Age quest officially begins.
If you miss that tablet, you could wander Pharloom for hours without ever understanding why Mister Mushroom never appears. Ask me how I know.
The Seven Mister Mushroom Locations
To complete the quest, I had to find Mister Mushroom in seven different locations. The game gives you riddles, not map markers. At each correct spot, I saw blue mushrooms with yellow circles on the ground. Then I played the Needolin, and Mister Mushroom popped out of the ground.
Here is the full list of locations and the clues that worked for me:
Order
Location
How I Found It
1
Moss Grotto
The spot between the bench and the snail shaman's home
2
Bone Bottom
Where Shakra used to appear in Bone Bottom camp, before entering Act 3
3
Far Fields
The edge of Far Fields, where lava is present in the area
4
Greymoor
Climb the Greymoor tower, then find a route up to the Wisp Thicket near the surgeon Yarnaby
5
The Slab
To the left of the First Sinner's cage, where the Rune Rage skill is found; the Key of Apostate is required
6
Mount Fay
Climb to the bird's nest; Silk Soar can skip a huge chunk of the platforming
7
The Cradle
Reach the peak and pass the parkour test of fitness
The order matters. I tried to skip ahead to The Cradle early, and Mister Mushroom simply refused to appear. The riddles must be solved in sequence, one location after another.
Reaching The Cradle
The final location is the hardest to reach. From the room to the right of the Cogwork Core, I looked upward until I found an opening. Silk Soar let me enter the gap, and I was transported to a side area of the Cogwork Core. From there, I kept climbing.
Along the way, I had to remember three key spots:
In the room where the Architect Melody puzzle once was, I had to find the correct spot to stand and lift myself upward.
At the place where I fought Lace for the second time, I again needed the super jump, but the light from above made the spot easy to find.
After the platform where I fought Grandmother Silk, I claimed the Pale Nails Silk Skill, then found the small opening above.
At the top of The Cradle, there is a cave. Inside, I faced a platforming challenge—a true test of fitness. After passing it, I played the Needolin one last time. Mister Mushroom finally spoke with Hornet, then soared upward and disappeared.
The Surface and Nameless Town
After Mister Mushroom vanished, I arrived on the surface in a place called Nameless Town. I whacked some cockroach-like bugs for the Hunter's Journal, then played the Needolin at the big skull cave to receive a Surface Memento. The surface was beautiful, but I still had a job to do. I headed back left toward the spikes, found a cave, and descended into The Cradle. From there, I returned to Pharloom to finish the catastrophe.
Getting the Passing of the Age Achievement
Here is the part that surprised me: completing the quest does not immediately pop the achievement. You must defeat the final boss of Act 3 after finishing the Passing of the Age quest. Defeating that boss unlocks a secret ending in addition to the normal ending. That means you can earn both endings and their achievements at once.
So, if you are hunting the achievement, do not wait until after the final boss. Complete the mushroom herald's journey first, then face the end of Act 3. Trust me, seeing that secret ending makes the entire strange mushroom hunt feel worth it.
After all, that age may pass—and this shroom its witness.
Hunting down seven hidden mushroom locations is the kind of obsessive, rewarding detour that reminds me why I keep coming back to games built around secrets. The catch is that games like this tend to send you looking for more of them — and with new releases rarely getting cheaper, filling a library with titles worth exploring can get expensive fast.
