In the sprawling kingdom of Pharloom, many NPCs offer assistance to Hornet, but few provide the comfort and tactical advantage of Kratt. As a merchant specializing in rejuvenation, Kratt is a character most players will want to locate as early as possible. However, his initial position is hidden behind environmental puzzles and ability gates, making him easy to miss during a first trek through the mist-shrouded ruins of the north.

Initial Location of Kratt in Greymoor

Kratt is initially located in the Greymoor region, a vast and atmospheric area characterized by its haunting bells and decaying architecture. To find him, players must head to the northeastern section of Greymoor, specifically near the sub-area known as "Halfway Home."

While exploring this region, players will encounter a large building that serves as a central hub. Kratt is not standing in the open; instead, he is trapped within a hidden room located just above the Halfway Home. Finding him requires a keen eye for architectural anomalies and the mastery of Hornet's movement abilities.

How to Reach the Hidden Room in Greymoor

Getting to Kratt is a multi-step process that involves overcoming a platforming challenge and discovering a secret passage. Unlike standard merchants who wait at benches, Kratt is a "rescue NPC," meaning his services only become available once he is freed from his predicament.

Required Abilities: The Cling Grip

Before attempting to reach Kratt, players must acquire the Cling Grip ability. This skill is essential for navigating the steep, vertical platforming sections of Greymoor. Without it, Hornet cannot maintain the necessary height to reach the upper ledges where the hidden room resides.

In our playthrough, we found that attempting this section with only the basic wall jump is frustrating and ultimately impossible. The Cling Grip allows for precise positioning, which is vital when scouting for the breakable wall that hides Kratt’s location.

Navigating from the Halfway Home

Start at the Halfway Home bench. Exit the building and head upward and to the right. The terrain here is treacherous, filled with decaying structures and narrow gaps. Look for a series of high platforms that lead toward the northeastern edge of the map.

As you ascend, pay close attention to the wall on the upper right side of the chamber. There is a section of the wall that appears slightly cracked or different in texture compared to the surrounding masonry. A single strike with Hornet’s needle will reveal a breakable wall.

Once the wall is destroyed, proceed through the opening into a concealed, silk-draped cavern. Inside, you will find Kratt suspended in a web, his distinctive metal carriage parked nearby.

Rescuing Kratt and the Lost Fleas Wish Quest

Rescuing Kratt is not just about unlocking a shop; it is also a requirement for completing the "Lost Fleas Wish" sidequest. When you encounter Kratt in the hidden room, he is wrapped tightly in silk. Simply strike the web to free him.

Upon being released, Kratt will express his gratitude in his characteristic high-pitched, eccentric tone. He mentions that he was attempting to join a flea caravan for safety but became ensnared by the "cursed threads" of Greymoor. Importantly, Kratt counts as one of the rescued fleas needed for the Flea Master’s rewards. If you have not yet freed five fleas, rescuing Kratt will provide a significant boost toward your next milestone in that questline.

The Flea Caravan and Kratt’s Post-Rescue Movement

One of the unique mechanics of Hollow Knight: Silksong is the Flea Caravan, a mobile group of NPCs led by Flea Master Mooshka. After you rescue Kratt in Greymoor, he does not stay in the hidden room. Instead, he packs up his spa-carriage and joins the caravan.

The caravan moves to different regions as you progress through the game. Depending on your current act and cleared objectives, you can find Kratt and the caravan in the following locations:

  • The Marrow: Often the first place the caravan settles after leaving the initial Bone Bottom area.
  • Greymoor: Near the southwestern bench, once the caravan catches up to your progress.
  • Blasted Steps: A later-game location where the caravan provides a much-needed respite in a harsh environment.
  • Flea Topia: The ultimate destination for the flea questline.

To find Kratt again after the initial rescue, simply look for the large, shaggy flea icons on your map that indicate the caravan’s current position.

The Spa Service: Benefits and Secrets

Kratt’s primary contribution to Hornet’s journey is his "luxurious spa-carriage." This service acts as a mobile healing station that is more potent than a standard bench but comes with a cost and a peculiar social dynamic.

Health and Silk Regeneration Mechanics

For a fee of 10 Rosaries, Kratt allows Hornet to enter his heated spa-carriage. Once inside, Hornet can submerge herself in the water. The effects are immediate:

  1. Health Recovery: Hornet’s masks regenerate rapidly at a rate much faster than focusing silk.
  2. Silk Replenishment: Her silk spool fills to the maximum, ensuring she is ready for the next boss encounter or platforming challenge.

In our testing, the spa is particularly useful before tackling the Moorwing boss in Greymoor or the Cogwork Dancers in the Sinner’s Road. For a mere 10 Rosaries, the time saved compared to hunting for smaller enemies to farm silk is well worth the investment.

How to Get the Spa Service for Free

Kratt has a hidden interaction that many players might miss if they are not paying attention. While Hornet is bathing in the spa, Kratt can sometimes be seen peeping through a small window at the top of the carriage.

If you notice Kratt peeking, you can jump up and strike him through the window. This triggers a unique dialogue sequence where Kratt panics and apologizes, claiming he was merely performing "repairs" on the carriage.

  • The Reward: After this confrontation, Kratt becomes extremely apologetic and considers Hornet a "treasured guest." From that point forward, he will offer the spa service for free (0 Rosaries).
  • Consequence of Inaction: If you do not catch him or choose not to strike him, you will be required to pay the 10 Rosary fee every time you wish to use the spa.

We highly recommend triggering this event as early as possible. While 10 Rosaries is a small amount, the cumulative savings over a 40-hour playthrough add up, and the interaction adds a layer of depth to Kratt’s eccentric personality.

Comprehensive Dialogue and Interaction Guide

Interaction with Kratt changes based on how Hornet treats him. His dialogue is voiced by Matthew Fitzgerald, lending a whimsical yet slightly unsettling quality to the character.

  • Initial Rescue: Kratt is fearful but grateful. He refers to Hornet by various flattering names like "nectar sweet" or "fair grace" before Hornet sternly corrects him.
  • Regular Service: "Do deshna, dear one, do deshna! Heh heh! Have you returned to use Kratt's luxurious spa-carriage?"
  • After Catching Him Peeping: His tone shifts to one of desperate supplication. "Auuuugghhh... the pain! Such fury, over a mistake! Poor little Kratt did not mean to steal a look!"
  • Playing the Needolin: If Hornet plays the Needolin near Kratt while he is at the caravan, he will sing along with lyrics about the "flea of fleas" and the "guiding light," hinting at the deeper lore of the Flea Caravan’s pilgrimage to the Pale Lake.

Why Kratt is Essential for 100% Completion

For completionists, Kratt is a non-negotiable NPC. He is tied to several completion metrics:

  1. The Lost Fleas Wish: As mentioned, he counts as a rescued flea.
  2. Ecstasy of the End: This late-game achievement/quest requires the rescue and relocation of specific NPCs, including Kratt, to the final area of the flea questline.
  3. Merchant Completion: To fill out the Hunter’s Journal and the merchant log, you must at least interact with Kratt’s spa once.

Furthermore, his presence in the Flea Caravan unlocks access to the Flea Brew tool in Greymoor, a red-slot item that increases movement and attack speed—essential for high-level combat.

Summary and Conclusion

Kratt is one of the most memorable and mechanically useful NPCs in Hollow Knight: Silksong. Finding him in the hidden room of northeastern Greymoor near the Halfway Home is a priority for any player who values efficient healing and quest progression. Remember to bring the Cling Grip ability and keep an eye out for that breakable wall. Once rescued, he provides a sanctuary within the Flea Caravan that can be upgraded to a free service if you catch his mischievous peeping. Whether you are aiming for 100% completion or just trying to survive the trek to the Citadel, Kratt’s spa is a luxury you cannot afford to overlook.

FAQ about Kratt’s Location

What happens if I miss Kratt in Greymoor? If you progress too far into Act 3 without rescuing him, Kratt can still be found, but the dialogue changes to reflect his increased fear of the "blackened beasts" infesting the land. He will remain in the hidden room until you break the silk.

Can I use the spa if I haven't joined the Flea Caravan? No, Kratt only offers his spa services once he is part of the Flea Caravan. In his initial location in Greymoor, his carriage is locked and he is trapped.

Is Kratt a hostile NPC? No, Kratt is a merchant. While you can hit him to bounce him around or punish his peeping, he will never engage Hornet in combat.

Do I need a specific key to find him? No keys are required to find Kratt, only the Cling Grip ability to reach the breakable wall and a weapon to break the wall itself.

Where does Kratt go after Flea Topia? Once the caravan reaches its final destination at the Pale Lake/Flea Topia, Kratt remains there permanently, providing his services for the remainder of the endgame.
