Passing of the Age is a late-game Wish in Hollow Knight: Silksong that becomes practical once you have Act 3 movement. You’ll follow a chain of riddles to track down Mister Mushroom in a specific order, then finish with a short platforming challenge above the Cradle. Completing the Wish adds a post-credits bonus scene and unlocks the related achievement/trophy.

Requirements and prep

You can start and complete this Wish cleanly in Act 3. Plan for traversal and summoning requirements:

  • Abilities: Silk Soar (high jump), Cling Grip, and Clawline. Faydown Cloak helps on Mount Fay but isn’t mandatory.
  • Tool: Needolin to draw Mister Mushroom out of hiding where blue mushrooms and spores mark the spot.
  • Order matters: You must visit all seven locations in sequence and speak to Mister Mushroom each time until he departs.

Start the Wish: find the tablet in Putrified Ducts

Step 1: From Fleatopia, head east into the Putrified Ducts. Navigate to the upper-right side of the cave system.

Step 2: Use Silk Soar to reach a small alcove in the top-right corner. The ledge is tight; jump directly beneath the light source to catch it.

Step 3: Interact with the glowing tablet to receive the riddles and start Passing of the Age. The quest log updates and the first clue points below the Ruined Chapel.

Mister Mushroom locations (in order)

At most stops, you’ll see blue mushrooms on the ground and spores rising; stand there and play the Needolin to summon Mister Mushroom, then speak to him until he leaves. Proceed to the next location only after he departs.

1) Moss Grotto — beneath the Ruined Chapel

Step 1: Drop from the Ruined Chapel into Moss Grotto and move east along the lower path.

Step 2: Stand on the blue mushrooms/spores marker and play Needolin to call him up, then talk to advance the Wish.

2) Bone Bottom — east of the board, near The Marrow access

Step 1: Return to Bone Bottom and move east past the Wish Board area toward The Marrow entry.

Step 2: Climb to the small platform above and to the left of The Marrow doorway, use Needolin on the mushrooms, then speak to Mister Mushroom.

3) Far Fields — eastern edge before the Needolin/Weavenest door

Step 1: Traverse Far Fields to just before the eastern Needolin-locked door.

Step 2: Use Needolin on the blue mushrooms, then speak to him to continue.

4) Greymoor — upper level near the Wisp Thicket access

Step 1: Reach Greymoor’s upper section using Cling Grip and Clawline, heading toward the Wisp Thicket entry.

Step 2: Drop through the small hole above his hiding spot, stand on the mushrooms, use Needolin, and talk to Mister Mushroom.

5) The Slab — near the First Sinner’s cage

Step 1: From the bellway bench in The Slab, go east to the area with the cage that leads to the First Sinner fight.

Step 2: Locate the mushrooms left of the cage area, use Needolin, then exhaust his dialogue.

6) Mount Fay — summit

Step 1: Climb Mount Fay to the peak. Faydown Cloak makes this ascent faster and safer.

Step 2: Mister Mushroom is already visible here; just talk to him to move the Wish forward.

7) The Cradle — peak, hidden passage

Step 1: Reach the very top of the Cradle. Stand on the right-hand platform at the peak and Silk Soar into a narrow hole above to enter a hidden passage.

Step 2: Follow the passage to a cave where you’ll drop onto a mushrooms/spores marker. Use Needolin and speak with Mister Mushroom for the final time.

Climb beyond the Cradle (short platforming gauntlet) and the surface

From the Cradle peak you can continue upward through a concealed route. Expect a compact platforming sequence that emphasizes Clawline jumps and precise Silk Soars.

Step 1: In the Cradle’s upper chamber (where you fought the Act 2 final), Silk Soar into a small roof cave to access the ascent path. If you’re missing the entry, try jumping from spots where ceiling debris falls to hint at a break.

Step 2: Work through the spike and wall-run sections methodically. If available, equip a loadout that lets you recover silk on hit, so you can safely heal during attempts.

Step 3: At the top you’ll emerge onto the desolate surface. Explore right to reach a small, nameless town; play Needolin at the far end to receive the Surface Memento. A leftward route over spikes links back down as a shortcut.

Finish the Wish and unlock the bonus scene

After the seventh conversation, Passing of the Age is complete. To see the extra Mister Mushroom scene and unlock the associated achievement/trophy, beat the true final boss; the bonus plays immediately after the standard post-credits sequence.

Troubleshooting and tips

Mister Mushroom isn’t appearing. Make sure you’re visiting the locations in order, standing on the blue mushroom patch with spores, and actually summoning him with Needolin. You must also talk to him until he leaves before the next spot will activate.

I can’t find the Greymoor or Bone Bottom spots. For Greymoor, you need the upper route near Wisp Thicket; drop through a small hole above his hide. In Bone Bottom, check the raised platform just before The Marrow access, to the right of the Wish Board area.

Blocked at the Cradle ceiling. The entry holes are tight. Jump from the correct tile and Silk Soar straight up; debris in the ceiling often hints at the right spot. Act 3 movement is assumed here.

Struggling with the ascent. Bring a survivability loadout and take the route in short segments. Enemies along the climb can be tapped to refill silk for healing. There’s a bench shortly after the final upward burst if you continue exploring.

Once you’ve done the seven stops and cleared the climb, all that’s left is the final fight—finish it again to see Mister Mushroom’s sign-off.
