Game Guide by TauxicPandA on Sep 09, 2025

For the Lost Fleas Wish, you need to find five Fleas that have been spread out in different places and bring them back to their Caravan. This Wish has several stages, and each one is harder than the last. Once you've finished it, you'll be able to travel to Greymoor.

Starting the Wish

In Bone Bottom, there is a town with a Wish Board where you can start your search. Check the board to agree to The Lost Fleas task. Once you have accepted, go to The Marrow in the next area to find the Flea Caravan in Hollow Knight: Silksong.

There are a lot of NPCs here who can give you more information about the Fleas that went missing. When you talk to them, your Wish objectives will change.

First Flea - The Marrow

The first person you need to kill is inside The Marrow. Moving up through this part is the most effective way to navigate.

Over the course of the game, you'll face different enemies that you can either fight or avoid. As you reach the upper areas, continue moving left and be cautious when encountering enemies.

To move up in the platforming sequence, you have to jump from one platform to the next. You'll have to get over a few gaps and land on certain levels in Hollow Knight: Silksong.

In this series, you have to jump to a platform, cross to the other side, fall and land on another platform, and then make one last jump. At the end of this path lies the first Flea

Second Flea - Hunter's March

The hardest Flea in the Wish is the second one. Find the resting place on the far right side of The Marrow, just below Hunter's March, before you try this stretch. You may die more than once in this section, so rest and make sure your money is either saved or spent.

From the place where you can rest, go up to get to Hunter's March. There is a challenging parkour course in this area that needs exact timing and execution in Hollow Knight: Silksong.

When you hit a spike trap, you'll need to attack downwards to bounce off of red items safely. Use jump-downward attacks to repeatedly hit these red parts without making any mistakes.

While going up, you have to avoid enemies and hit groups of three red bouncing points. For the most challenging part, you need to follow a particular pattern: down, right, left, right, down, left, down, down, right, up. During this process, be careful how you move your joystick. Keep it lower and to the sides to avoid attacks that happen at the wrong time.

Move through the left path by jumping up and hitting down, then move from left to right and up. To complete the last step, go right twice and then up to reach the caged Flea and set it free in Hollow Knight: Silksong.

Third Flea - Deep Docks

Once the Swift Step skill is unlocked in Deep Docks, this Flea is easy to get to. From where you got Swift Step, move to the left and use your new rushing skill to fly through the air. You can get to the higher area where the third Flea is waiting because you can move around more easily.

Fourth Flea - Deep Docks

Go back to the part of Deep Docks with the teleporters where you beat the fast-traveling worm thing. Break through the left wall when you jump into this area to get to a cave that leads further to the left. The Flea floats above you, and you have to get through a platforming game while staying away from lava in Hollow Knight: Silksong.

As you jump from one platform to the next, you can fight flying enemies as needed. To make sure you stay safe, wait for the flames to stop between each jump. Repeat this process of jumping and waiting until you reach the location where the Flea is.

Fifth Flea - Far Fields

Quick Travel will get you to Far Fields. From there, go left and cross the area. As much as possible, stay on higher levels and keep moving across the land. You can navigate the area by jumping over holes and then climbing up when you reach the correct part.

After you climb up, go to the right side to find a fake wall that you can break. Cut down this wall and proceed directly into the secret area in Hollow Knight: Silksong.

The last Flea can be found at the top of this part. Be cautious when entering the tunnel, as a trap is set to trigger a fight. Get out of the trap right away and beat the enemy that appears before you.,u free the last Flea.

Completing the Wish

Once you have all five Fleas, go back to the Flea Caravan in The Marrow. Talk to the NPC to finish The Lost Flea's Wish. After you finish, you'll be able to choose to move with the Flea Caravan. If you accept this deal, you will be taken to Greymoor, where you can explore new areas in Hollow Knight: Silksong.
