Complete Guide to All Silksong Flea Locations in The Lost Fleas Quest

Introduction

Embarking on the quest to find all five fleas for Fleamaster Mooshka in Hollow Knight: Silksong offers a thrilling challenge reminiscent of tracking down caterpillar grubs in the original game. However, this time, you only need to locate five elusive fleas scattered throughout the lower regions of Pharloom. This guide will walk you through the locations of each flea, ensuring you can return them safely to the flea caravan for rewards.

Starting the Quest

You can initiate The Lost Fleas quest with Fleamaster Mooshka in The Marrow, shortly after leaving Bone Bottom. All five fleas are situated in areas accessible before reaching Greymoor and the higher regions of Pharloom. Let’s dive into their specific locations.

Flea Locations

Flea Location #1: The Marrow

The first flea can be found shortly after defeating the Bell Beast. Follow these steps:

• Exit the boss arena by heading right past the bench room into a large open chamber.
• Activate the lever to open the shortcut but refrain from proceeding to the Deep Docks. Instead, climb the platforms to the upper section of the chamber.
• In the upper right corner of the room, navigate left along the platforms and ascend. Drop down after defeating the second large skull enemy to find the flea tangled in vines.

Flea Location #2: Deep Docks Bellway

This flea is relatively easy to find:

• In the Deep Docks Bellway, smash the left-hand wall adjacent to the Bell Beast’s location. You may need to jump slightly.
• Once inside, navigate through a lava-based platforming puzzle to reach the flea, which is located directly above the entrance.

Flea Location #3: Also in Deep Docks

The next flea is positioned just left of the platforms where you acquire the Swift Step ability:

• After obtaining the Swift Step, jump left across the platforms in the same room.
• Activate the lever at the far end to lower the bell, then use it to access the section above where the flea is trapped.

Flea Location #4: Far Fields

To find the fourth flea, follow these steps:

• Travel to the Far Fields Bellway (you’ll need the Drifter’s Cloak from the Seamstress to access this area).
• Exit and jump left across the chasm into the adjacent room.
• Ascend the platforms on the left, then reach the far right side of the next room to smash a secret wall.
• Climb up a couple of platforms to find a passage blocked by bone containers. Smash through them to enter the area (be cautious of a red ant waiting to capture you).
• Free yourself from the cage and break open the flea’s cage to rescue it.

If you haven’t obtained the Drifter’s Cloak, you can still access this flea by looking for two red ants on a platform above you while entering Far Fields via the main path. Sprint and jump up the platforms to reach the top of the room, then proceed from step 2 above.

Flea Location #5: Hunter’s March

The final flea is located in the Hunter’s March area:

• Defeat the large red ant boss positioned at the far upper right of The Marrow.
• Once defeated, utilize downward attacks on the red orbs to bounce yourself up to the top of the next room, where you’ll find the last flea.

Returning to Fleamaster Mooshka

After successfully locating all five fleas, return to Fleamaster Mooshka. He will guide you to the far left side of Greymoor, effectively skipping a significant portion of the main path. Additionally, by interacting with the other fleas at the caravan, you’ll receive three charges of Flea Brew, which temporarily boosts your movement speed and attack power.
