Hollow Knight: Silksong introduces Vog as a key NPC who assists players in the tricky quest of finding Lost Fleas scattered across Pharloom. Vog is initially found in a hidden area above the Bellway station within the Putrified Ducts region, a mid-game area accessible after gaining certain movement abilities like the Faydown Cloak. Talking to Vog allows her to join the Flea Caravan, where she can sell map markers to highlight lost fleas still hiding on the map.

How to reach Vog in the Putrified Ducts

This ascent blends precision platforming with enemy-riding tactics, turning Barnaks vines from threats into elevators. Expect 10-15 minutes if you're practiced, longer with retries on spike fields. To begin with, save at the Bellway Station bench beforehand.

Step 1: Go down from the Bellway Station bench

Exit the Bellway Station bench in Putrified Ducts from the left.

Drop into the wide east-west room southeast of Bellway Station.

Once you leave the area, go up and to the right. Avoid enemies, if you can, and go past them using Cling Grip and Faye Down as much as possible.

Step 2: Navigate the horizontal spike chamber

Traverse rightward, pogoing off Barnak tongues for height boosts while Swift Stepping over spike pits.

At the far end, climb vine-wrapped platforms, then double back left—watch for a fragile ceiling section that crumbles under repeated jumps.

Step 3: Breach the hidden upper passage

Strike the suspicious wall segment with three charged needle thrusts to reveal a crawlspace.

Squeeze through to the elevated ledge, then cling to the right wall using Cling Grip. Shimmy up, parrying any patrolling silkstruck mid-climb to avoid falls.

Step 4: Ride the Barnak elevators skyward

Enter the vertical spike shaft. Dash into the nearest Barnak's gaping maw—it'll hoist you upward to a new spike field.

Repeat: Swift Step across thorns, latch onto the next Barnak, and let it ferry you higher. Three lifts total, with brief enemy waves between; time parries to build resonance for silk bursts that clear clusters.

Step 5: Claim your flea merchant

The final lift deposits you in a misty alcove. Approach Vog for dialogue.

She'll grunt about her "important work" before hinting at the nearby Caravan. Backtrack via the new silk highway shortcut to exit swiftly.

Success here not only nets Vog but reveals a nearby Lost Flea cache, accelerating Caravan upgrades. If Barnaks prove tricky, equip the Bell Chime charm for time-slowed dashes.

What happens after talking to Vog (gain map)

Once players interact with Vog at her hidden location, she announces her intention to join the Flea Caravan, which is usually stationed near the Grand Gate. When Vog relocates to the caravan, players can speak with her again to purchase special Flea Map markers using Rosaries.

These markers mark the locations of any Lost Fleas that players have not yet found, streamlining the quest to rescue all 30 Lost Fleas scattered across the world.

Reaching Vog transforms the Lost Fleas quest from a difficult scavenger hunt into a manageable task by unlocking map markers that highlight fleas. Starting from the Bellway bench, this short but challenging platforming route rewards careful movement and timing to access a key resource for Silksong’s flea quest.
