Hollow Knight: Silksong: The Lost Fleas Quest Guide for 2026
https://dealnesthq.com
I have a confession: I spent my first few hours in Hollow Knight: Silksong treating every new room like a buffet of bad decisions. Then I met Mooshka and the Flea Caravan, and suddenly I had a purpose that was not just poke everything and hope. The Lost Fleas quest is one of the earliest side quests in Pharloom, and as of 2026 it remains the best early-game power spike that does not involve selling your soul to a creepy merchant. You find five fleas, you get Flea Brew, and boss fights become slightly less like slamming my head against a musical wall. Getting the Lost Fleas Quest As soon as you leave Bone Bottom, head into The Marrow. You do not need any fancy ability to start this quest, which is great because my early Hornet had the grace of a shopping cart with one wobbly wheel. Find the Flea Caravan near the middle area of the Marrow and talk to its master, Mooshka. You will also see Grishkin and Varga hanging around, plus a Bench that feels like a five-star hotel compared to some later resting spots. From the Bone Bottom entrance, use the platforms above you to reach the upper area. Make your way right until you hit a vertical structure. Go down, then take the first entrance on your left. Mooshka will explain that the fleas are lost across Pharloom and ask for your help. Accept the quest. Boom, you are now a flea rescue service. A quick tip that saved my sanity: put on headphones. The fleas cry, snore, and make tiny noises that are easy to miss over combat. Listening for them is like panning for gold in a river of noise, except the gold occasionally snores. There are 15 fleas total, but the quest only needs five. I still recommend grabbing the early five fast, because the reward is a warm hug in tool form. Five Lost Fleas Locations Here is the short version for my fellow players who navigate by vibes and regret. Flea Region Ability check Vibe 1 The Marrow None Platforming with aerial enemies 2 Deep Docks Swift Step Dash to the upper level 3 Hunter's March Swift Step helps Mini-boss then red buds 4 Far Fields None, but combat Hidden wall and cages 5 Shellwood Drifter's Cloak Spikes, flowers, gliding 1. The Marrow After you beat the Bell Beast, head right until you enter a big open chamber. Hit the lever, climb the platforms to the top, and enter the room above. This is where my platforming felt like trying to thread a needle while riding a unicycle through a hurricane. There are aerial enemies, so stay patient. The flea is trapped in vines in the upper right corner. You have to loop around from the left side to reach him. It might take a few tries. That is fine. The flea believes in you, probably. 2. Deep Docks Once you unlock Swift Step, do not leave the room where you got it. Seriously, just look up. Dash your way to the upper level of the chamber. There is a little parkour, because of course there is, and the flea is trapped inside some black eggs. Break him out. This one is a victory lap if you resist the urge to immediately fast travel away like I did the first time. 3. Hunter's March The third flea is at the beginning of Hunter's March, a small optional region connected to The Marrow. The entrance is guarded by a Skarrguard above the Marrow's prison, near where you first meet Grindle. With Swift Step, you can dash around his heavy attacks and make him look silly. After the mini-boss, go right into Hunter's March. Follow the tricky platforms and buds. Hit the buds for a bounce. When you can go right or up, choose up. Use the red buds, avoid the spikes, and you will find a flea sleeping in a cage at the top. He is having a better day than I was during that spike section. 4. Far Fields The fourth flea is in a hidden passage on the right side of the main Far Fields chamber. From the Deep Docks entrance, head right into the next horizontal area. Keep walking until you see two red ants chilling around a lantern on a
