All Lost Fleas in Hollow Knight Silksong
How to find all 5 Fleas for Fleamaster Mooshka
Looking for the Lost Fleas in Hollow Knight: Silksong? One of the early quests in Silksong occurs when you run into Fleamaster Mooshka and the Flea Caravan, a jolly bunch found in The Marrow. Fleamaster Mooshka will ask Hornet for help in finding five lost Fleas. Completing this quest will let you fast travel with the caravan to Greymoor and avoid an extremely hard early boss. It'll also put you on the path of locating many more Fleas for Fleamaster Mooshka in a long search that encompasses all of Pharloom.
If you're having trouble finding these fuzzy creatures, we're here to help. In this guide, we'll outline how to complete The Lost Fleas quest in Hollow Knight: Silksong.
All Lost Fleas locations in Hollow Knight: Silksong
We've outlined the locations of the 5 Lost Fleas that you need to complete Fleamaster Mooshka's initial quest below. Once again, there are many, many Fleas hidden throughout Pharloom, but this guide is focused on the 5 easiest-to-find ones so that you can complete the quest as quickly as possible.
Lost Flea #1
You can find the first Flea on a high ledge in the northern stretch of The Marrow.
You can get here easily by going east from Mosshome, using the platforms to climb upwards, and then following the left path across the spikes. Then venture rightwards near the ceiling of the room until you see the Flea stuck in a bunch of greenery.
Lost Flea #2
The next Flea can be found behind the Bellway in Deep Docks.
Jump over the Bell Beast, hit the left wall to unlock a hidden corridor, and then time your jumps across the lava platforms until you head upwards and find a frightened Flea cowering on a rocky ledge to the right. You'll need to attack it to snap it to its senses.
Lost Flea #3
Your third Flea is located on the upper left level of the same long room where you acquire the Swift Step dash skill.
Parkour up the metal ledges to your left; hit the lever to open a new route above you, and head upwards to find a Flea trapped in an egg. Attack it and it'll be free.
Lost Flea #4
The fourth Flea is located in Far Fields, within a hidden room that branches out from the far right side of a vertical shaft.
The room has low visibility and contains several platforms; when you come to the first path on the right, watch out for the white pressure plate on the ground that will snare you in a trap and leave you as helpless fodder for an ant enemy. Once you bypass the trap, you can find the Flea stuck in a cage at the end of the path.
Lost Flea #5
Your fifth Flea is located in Hunter's March and requires some expert Pogo-ing to reach.
From the entrance to Hunter's March via The Marrow, go west and then Pogo up all of the red plants until you get to a vertical fork in the road. Take the left path and watch for the flying ants. At the very top, past the spikes, you'll find your Flea in a cage.
What happens when you find the 5 Lost Fleas?
After you've found the above Fleas, return to Fleamaster Mooshka in The Marrow (see our walkthrough if you've forgotten where he is) to complete The Lost Fleas quest.
Mooshka asks if you'd like to ride with him and his fuzzy friends, and if you accept, you'll be transported to the Flea Caravan's new resting place on the outskirts of Greymoor. How convenient!
Note that if you don't complete The Lost Fleas, it's still possible to reach this entrance to Greymoor on your own - however, once you get there, you'll be met by the Moorwing, a frustrating boss that's likely to kill you more than a few times.
Finishing The Lost Fleas is thus a great way to bypass this tough encounter until you're a bit more ready. Moorwing can be faced later outside the Bellway Entrance of Greymoor once you reach Act 2 of Silksong.
Now you know how to save all of those little Lost Fleas in Hollow Knight: Silksong.
