To move Fleamaster Mooshka’s caravan, rescue five Lost Fleas and return to speak with him. That is the initial objective of The Lost Fleas wish—not the full collectible hunt: the wider guide covers 30 fleas, with the Egg of Flealia reported as the completion reward. You can start the wish at Bone Bottom’s Wishwall or by finding Mooshka and his caravan in the Marrow.
How to start The Lost Fleas
The Lost Fleas is a Wayfarer Wish associated with Fleamaster Mooshka. Accept it from the Wishwall in Bone Bottom, or speak to Mooshka at the caravan in the Marrow. His request is to rescue five lost fleas so they can travel safely together. The quest reference records the wish and its stated objective.
Five fleas or all 30: which goal are you working toward?
| Goal | What to do | Reported result |
|---|---|---|
| Initial wish | Rescue five fleas, then return to Mooshka. | Mooshka progresses the caravan move to Greymoor. After it arrives, talk to Grishkin for Flea Brew, according to the quest reference. |
| Full collection | Find the wider set of 30 Lost Fleas. | Nintendo Life’s guide reports the Egg of Flealia for collecting 30. It also lists service and item milestones; exact intermediate thresholds are not established here. |
The five-flea request and 30-flea completion are separate milestones. If you only want to advance the caravan, you do not need to treat the full collection as the initial requirement.
Early Lost Fleas by region
Use region names rather than guide numbering: walkthroughs can order or number pickups differently. These examples show why the shortest early route may depend on which movement abilities Hornet has already unlocked.

Marrow
The first flea is in the Marrow, where Mooshka’s caravan is found. The Silksong Wiki walkthrough lists a Marrow flea that requires no ability, making it a practical early pickup. See its Lost Fleas walkthrough for the route.
Deep Docks
The walkthrough identifies two different Deep Docks pickups: one below, reached through a secret wall and a lava-timing traversal, and another higher up that requires Swift Step. These are distinct route checks, so do not assume finding one means the other is accessible. The same walkthrough gives the ability and hazard details; GameSpot’s guide also provides maps and routes for early pickups.

Far Fields
One listed Far Fields flea requires Drifter’s Cloak. If you reach the area before having it, mark the location and return later rather than spending time trying to force the route. The walkthrough identifies this gate.
Hunter’s March
The early Hunter’s March example involves pogo-jumping to reach the flea. If the platforming route is unclear, consult the region maps in Nintendo Life’s guide or GameSpot’s guide.

How to route the full collection without needless backtracking
- Collect accessible fleas as you explore. The Marrow pickup is listed without an ability requirement, while some later examples are ability-gated or involve a hidden route.
- Note the obstacle when you cannot reach one. Record whether it needs Swift Step, Drifter’s Cloak, a hidden-wall entrance, lava timing, or pogo-jumping, then leave it for a return trip if needed.
- Use a region map for hidden or hazardous routes. Nintendo Life and GameSpot provide region-by-region map and route guides for the larger hunt. This guide does not reproduce every location on the 30-flea route.
- Choose your stopping point. Return after five rescues to progress the initial wish; continue using the full maps if you are pursuing all 30.
Caravan progression and rewards
After five rescues, return to Mooshka to progress the caravan move to Greymoor. Once the caravan arrives, the quest reference says Mooshka points Hornet to Grishkin, who gives her Flea Brew. For the larger hunt, Nintendo Life reports the Egg of Flealia at 30 fleas. Walkthroughs may differ in their ordering and intermediate milestone details, so use the in-game wish and current route maps to track what remains rather than treating every guide’s numbering as universal.
