In Hollow Knight: Silksong, every small discovery adds to the grand tapestry of Pharloom. Among these discoveries is Kratt, a peculiar flea NPC tied to the quest known as the Lost Flea’s Wish. Players who stumble across his cocooned form in Greymoor quickly realize that he is more than just another wanderer—Kratt is a companion who transforms the Flea Caravan into a true sanctuary. This guide explores Kratt’s exact location, how to free him, his role in the caravan, and the secret interaction that unlocks his service for free.

Silksong Kratt Complete Walkthrough

Where to Find Kratt in Silksong?

Kratt’s story begins in Greymoor, one of Silksong’s shadowy, web-riddled regions. To reach him, Hornet must first acquire the Cling Grip ability, allowing her to climb and navigate the tall spindly towers in the western section of Greymoor.

Start from the second doorway on the right in this area.
Follow the path until you reach a switch that activates an elevator near Halfway Home.
Ignore the lift and instead continue platforming across the upper route.
Enter the first doorway to the right. At the end of this path lies Kratt, bound in silken webs.

Free him, and Kratt will make his way to the Flea Caravan, awaiting you in your onward travels.

Kratt’s Role at the Flea Caravan

Once rescued, Kratt establishes himself as the caravan’s spa master. This service is far from a trivial luxury:

For 10 Rosaries, Hornet can bathe in the spa, restoring both health (masks) and Silk.
The spa functions much like a mobile bench alternative, making the caravan an invaluable checkpoint for longer expeditions.

Kratt’s arrival elevates the caravan’s importance. With Vog’s flea-tracking, Flea Brew for supplies, and Kratt’s healing spa, the caravan transforms into a roaming hub of safety and preparation.

Unlocking Free Access to Kratt’s Spa

Here lies one of Silksong’s quiet secrets. While using the spa, keep an eye on the upper corner of the screen—you may notice Kratt peeking in.

Strike him once during this moment, and he will relent, offering free, permanent access to the spa from then on. This small act of mischief ensures Hornet always has a place of recovery without draining precious Rosaries.
