Where to find all Lost Fleas in Hollow Knight: Silksong

The Lost Fleas wish/side quest comes from a group of NPCs led by Fleamaster Mooshka. You’ll find these fellas in a zone called The Marrow. From the lower section, you need to climb up past the spike traps and platforms. You should then see a flea signboard to your left. The encampment also has a bench that you can rest on to replenish your health.
