If you miss the grubs from Hollow Knight, then Silksong has its own edition of cute critters in trouble called Fleas. The travelling Flea troupe’s Fleamaster asks you to help find 5 Fleas. Here are the locations of all 5 Fleas in the starting areas of Hollow Knight Silksong.
How to Start Lost Fleas Quest
To start the Lost Fleas quest, you need to speak to the Fleamaster and accept the task he assigns you. You can find them fairly early on, near the middle area of the Marrow. The exact location is shown in the image below.
How to Find 5 Lost Fleas
Flea #1 Location
The first Lost Flea is nearby in one of the upper chambers of the Marrow. You’ll have to loop around from the left side and make your way to the trapped Flea on the right.
It’ll require a whole bunch of platforming while dealing with some aerial enemies. At this stage in the game, you might need a few tries, but it’s definitely doable.
Flea #2 Location
The second Flea is located in the Hunter’s March, which can be difficult to access because it requires you to defeat a powerful Skarrguard at the entrance. Once you’re inside, follow the path of buds, and one of them leads to the Lost Flea.
Flea #3 Location
This Flea is hard to miss because you can find it right after getting the Sprint ability. It’s in the chamber to the left, and you just need to parkour a bit and make your way to the upper areas of this chamber.
Flea #4 Location
The fourth Flea is located in a hidden room on the right side of the main Far Fields chamber near the bottom. You can break the wall and head into this room after entering the main vertical chamber.
Before heading in, make sure you’re at full health and ready for combat, as a cage traps you and a Skarr Scout will attack you from behind.
Flea #5 Location
The fifth and final Flea is located near the upper right portion of Craw Lake and requires a bit of aerial platforming to reach.
Beware the Tallcraw that guards the entrance and the Mite below, which can catch you off guard.
Lost Flea Quest Reward
Once you have collected all 5 lost Fleas, return to the Fleamaster at the Flea Caravan and he will offer for you to travel with them. Even if you don’t travel with them, you can still run into them again, and this is just a quick skip to a later area.
Then you are taken to a new location past Greymoor and Halfway Home, from where you can access Bellmont. You’ll also gain the Flea Brew offensive charm, which is a consumable that can increase your movement and attack speed.
