There are 30 Lost Fleas in Hollow Knight: Silksong, and players are likely to come across many of them while exploring Pharloom. However, finding every Lost Flea can be quite tricky, though there is an NPC that is willing to assist with the endeavor. That NPC is Vog, and the items that he sells cause the locations of all the remaining fleas to be marked on Silksong's in-game map.
Players should find 15 Lost Fleas and get the Flea Caravan to move to the Grand Gate before they pursue Vog.
Vog Location in Silksong
Go to the Putrified Ducts
The first step towards finding Vog is reaching the Putrified Ducts, an area that is to the right of Memorium and above Bilewater. To access this area, players must unlock the
Faydown Cloak and use that ability to enter Memorium near the top-right corner of the Choral Chambers. This guide to reaching the Putrified Ducts in Silksong provides full details on this process.
This guide to getting the Putrified Ducts map in Silksong may also be of interest, as having access to that map will make finding Vog much easier.
Players should now make their way to the position that is marked on the preceding map. Here, players will find an elevated platform, and the wall to the left has a cracked section that can be broken. After breaking through that wall section, players should follow the path to the left and up to access a new screen.
There are several Barnaks hanging from the ceiling during this part of the journey, and they will attempt to grab Hornet with their tongues. Additionally, there are some spiked floors that can easily be bypassed with double jumps and Swift Step.
This new screen is filled with spikes and Barnaks, and the strategy is to use Silksong's Swift Step ability to dash over the spikes and into the tongue of a Barnak. Players should then allow the Barnak to lift Hornet to another spike-filled area, repeating this process until they get to the top. This section is demonstrated in the following video, and players should go left once they reach the top to find Vog.
How to Get Flea Map Items in Silksong
After locating Vog, players should speak with him, and the flea will indicate that he is going to join the caravan. Players should now simply make their way to the Flea Caravan stationed near Grand Gate, and they will find Vog to the right of Fleamaster Mooshka. Players can then speak to Vog once again and exchange Rosaries for an assortment of items that will mark any remaining Lost Fleas on the in-game map.
