Hollow Knight Silksong Fleas Guide | All Flea Locations
The Lost Fleas quest in Hollow Knight Silksong asks you to rescue five hidden fleas across Pharloom. Much like the grubs in Hollow Knight, these fleas are caged and must be freed, but there are only five to find. This guide shows all flea locations and how to complete the quest for Fleamaster Mooshka.
How to Start The Lost Fleas Quest
You can begin the quest by speaking to Fleamaster Mooshka in The Marrow, shortly after leaving Bone Bottom. He will ask you to find and rescue the fleas scattered across lower Pharloom.
All Flea Locations in Silksong
Flea 1: The Marrow
After defeating the Bell Beast, head right past the bench room into the large open chamber. Open the shortcut lever, then climb the platforms to the top. Enter the room above, go left across the platforms, and drop down near the second large skull enemy. The flea is tangled in vines in the upper right corner.
Flea 2: Deep Docks Bellway
In the Deep Docks Bellway, break the left-hand wall just left of the Bell Beast’s location. Inside is a lava platforming puzzle. Navigate it carefully and you’ll find the flea napping above the entrance.
Flea 3: Deep Docks Shrine
After acquiring the Swift Step ability from the shrine, use it to dash left across the platforms. Hit the lever to lower a bell and jump up to reach the section above. The flea is trapped there and can be freed once you reach it.
Flea 4: Far Fields
From the Far Fields Bellway, head left across the chasm and into the next room. Break a secret wall on the far right side, climb up, and smash through the bone containers blocking the path. A red ant will ambush you, trapping Hornet in a cage. Break free, defeat it, and then smash the flea’s cage.
Flea 5: Hunter’s March
Defeat the large red ant boss in the far upper right passage of The Marrow. This area is above the prison bench where you meet Grindle. After winning, use downward attacks on the red orbs to bounce upward through the room. At the top, smash the flea’s cage to free it.
Rewards for Saving All Fleas
Return to Fleamaster Mooshka after rescuing all five fleas. He will lead you to the far left side of Greymoor, letting you skip a large section of the main path. Talking to the other fleas at the caravan also gives you three charges of Flea Brew, which temporarily boosts Hornet’s movement speed and attack power.
Final Blurb
The Lost Fleas quest in Hollow Knight Silksong only has five locations, but they are hidden across The Marrow, Deep Docks, Far Fields, and Hunter’s March. Saving them all not only progresses Fleamaster Mooshka’s story, but also rewards you with shortcuts and Flea Brew buffs.
