One of the first few Wishes that becomes available to you in Hollow Knight: Silksong is The Lost Fleas. This side quest has you track down five of the Flea Caravan’s lost fleas.
Similar to the Berry Picking Wish, you have to go on a scavenger hunt to find these creatures in order to receive a nice reward. If you’re still on the prowl for these adorable pups, we’ll detail where to find all five of the lost fleas in Silksong.
All 5 Lost Fleas locations in Silksong
Flea #1
The first flea you can find is high up in The Marrow. From the Bench nearest to the Bell Beast fast travel point, head right and then climb north. You’ll reach a new, spacious room with tons of platforms and bugs.
You’ll find this trapped flea in the northeastern corner of this room. Just break the branches that are keeping it trapped.
Flea #2
This next flea is in Hunter’s March, hidden behind a path of those red buds you have to pogo jump across. Start from the bench on the eastern side of The Marrow, then climb up and to the right to enter Hunter’s March.
From here, follow the red buds until you reach a fork in the road. Instead of going right, head to the left path, and it’ll lead you to a flea stuck in a bone trap. Break this trap to free him.
Flea #3
The third flea is near the area where you learn the Swift Step ability in the Deep Rocks. Now that you can sprint, run up the platforms to the left of where you picked that ability up. At the end of this path is a platform on the western wall with a lever.
Hit the lever, and it will drop down a platform for you to use. Take this platform up, and you’ll find the third flea smushed inside a black shell. Repeat what you’ve done before to free him.
Flea #4
The fourth flea you can find in the Far Fields. If you haven’t unlocked the fast travel here yet, the easiest way is from the bench in the Deep Rocks that connects to the Far Fields.
Pass through the first main room until you find a much bigger room. Climb up to the ledge with the two ant enemies resting, pass them, and use your sprint ability to climb up onto the wooden platforms above. Keep heading west from there, and you’ll find an exit above.
In this next room, head east into the next exit, and you’ll make it to a vertical room. Climb up until you reach a small hovel on the right side where the flea is trapped. Just make sure to avoid the trap on the floor that will encase you in a similar trap, as an ant enemy will come to fight you.
Flea #5
The fifth and final flea is stuck in Craw Lake. From the rest spot in this area, head east until you make it to Craw Lake. You’ll have to hop on some platforms to get to this flea stuck inside of a shell on the eastern side of this room.
Now that you’ve tracked down all of the fleas in Hollow Knight: Silksong, you should make sure that by this point, you’ve acquired the Straight Pin tool.
