Junk Pit Hollow Knight Guide

Junk Pit icon, the trash cavern in Royal Waterways in Hollow Knight
Sub-area / Hollow Knight (Godmaster DLC)

The trash-filled cavern at the southwest bottom of the Royal Waterways. Holds the Godseeker sarcophagus, the Fluke Hermit, and the Godtuner that opens Godhome.

Main area: Royal WaterwaysGate item: Simple KeyReward: Godtuner

The Junk Pit is the trash dump of Hallownest. Per the wiki, the massive cavern sits at the southwest bottom of the Royal Waterways and collects every piece of refuse the capital sewer system flushes down. The pile catches Geo chests, ruined paintings, a statue identical to the one where Monarch Wings are picked up, and one golden sarcophagus.

According to the wiki, the sarcophagus holds the Godseeker, who has been "hibernating" in the pile since the kingdom fell. A Simple Key opens the box; freeing her drops the Godtuner item and starts the Godmaster DLC storyline.

The wiki notes the Fluke Hermit, one of two NPCs in the chamber, calls the trash pile "Flukemarm’s treasure." Flukemarm herself sits one room north as a boss; the lore links the rubbish, the boss’s hoarding instinct, and the wider Royal Waterways drain pattern.

This guide covers the Royal Waterways access route, the breakable-roof entry next to Flukemarm’s arena, the Simple Key sources, the Godseeker sarcophagus mechanic, the Godtuner drop, the Awoken Dream Nail Godhome unlock, the Fluke Hermit Dream Nail dialogue, the secret Cast-Off Shell 2% room, and the Nailsmith-corpse easter egg if the Knight kills him in Dirtmouth.

  • What it is Junk Pit icon Trash cavern at the bottom of Royal Waterways; sub-area, not a main region.
  • Key item Simple Key icon Simple Key opens the Godseeker sarcophagus on use.
  • Reward Godtuner icon Godtuner; unlocks pantheon-completion tracking.
  • Skip when Godseeker icon Pre-Mantis Claw; the breakable roof entry needs wall-cling for the climb back.

What the Junk Pit Is

Per the wiki, the Junk Pit is the literal dump of Hallownest. The Royal Waterways pipes were built to carry the City of Tears waste outward, but the rain from Blue Lake washed the pipes clean of effluent; only solid refuse remained, and the current swept it all into this single cavern.

According to the wiki, the pile mixes high and low value items: Geo chests, paintings, broken statues, plus a single golden sarcophagus. The sarcophagus reads as misplaced; everything else looks like trash. The visual joke is the wiki-flagged centrepiece of the room design.

The wiki specifies the Junk Pit is one of the few rooms in the game that gates a major system behind a chamber that feels structurally minor. The whole Godmaster DLC routes through this single room; without the Godseeker pickup here, none of the Pantheons open.

Royal Waterways Access Route

Royal Waterways icon Per the wiki (patch v1.4.3), the Junk Pit requires Mantis Claw, the City Crest entry to the Royal Waterways, and a Simple Key. The breakable-roof entry sits in the northwest corner of the square-shaped area next to Flukemarm’s boss room; a single Desolate Dive cracks the floor and drops the Knight into the pit chamber.

  1. Enter the Royal Waterways. According to the wiki, the canonical entry is from the City of Tears via the Simple Key gate in the central plaza. The alternate routes are the Forgotten Crossroads tram (needs Tram Pass) and the Crystal Peak elevator dropdown.
  2. Reach Flukemarm’s arena. Per the wiki, Flukemarm sits in the southwest of the Waterways. The fight is optional for the Junk Pit entry but mandatory for the Flukenest charm. Flukemarm has 350 HP and a fluke-spawn pattern.
  3. Break the floor above the Junk Pit. The wiki notes the breakable roof is one screen north of Flukemarm’s arena. Desolate Dive is the cleanest break; Howling Wraiths from the ground also works but eats more Soul.

According to the wiki, a secondary breakable wall at the top of the Junk Pit chamber connects upward to the City of Tears, directly below the Nailsmith’s forge. This is a one-way shortcut; the wall breaks from inside the pit only, and the route saves roughly three minutes of backtracking on every return trip.

Simple Key Sources

Simple Key icon Per the wiki, the Junk Pit sarcophagus accepts only a Simple Key. The game ships four Simple Keys total; the Godseeker unlock is one of four locks that consume the keys on use.

SourceCost or conditionNotes
Sly’s shop (Dirtmouth)950 GeoStandard early-game pickup
City StoreroomsHidden room dropBehind a Husk Sentry chest
Pale Lurker (Trial of the Fool)Boss killOptional fight inside the trial arena
Ancient Basin chestHidden chestRequires Crystal Heart for the chamber

According to the wiki, the cleanest route for first-time Junk Pit clears is the Sly purchase. The 950 Geo cost is trivial mid-game, and in practice the other three keys gate higher-priority pickups (Pleasure House Hot Spring, the Royal Waterways Soul Sanctum-adjacent door, and the Ancient Basin Pale Ore).

Build Tip

Buy the Simple Key from Sly before attempting the Royal Waterways. Per the wiki, the City of Tears gate from the central plaza also consumes one Simple Key; arriving without two keys in inventory forces a backtrack to Dirtmouth mid-progression.

Godseeker Sarcophagus

Godseeker icon Per the wiki, the golden sarcophagus at the bottom of the Junk Pit contains the Godseeker, a devotee of "the Gods of Hallownest" who has been hibernating since the kingdom fell. She is the central NPC of the free Godmaster DLC.

According to the wiki, inserting the Simple Key into the sarcophagus opens it and frees the Godseeker; she remains in the chamber as a sleeping body. The Knight then has two interactions available: pick up the Godtuner she drops, and (separately) Dream Nail her sleeping form.

The wiki specifies the Godseeker can only be Dream Nailed with the Awoken Dream Nail. Standard Dream Nail hits return no animation and no portal; the Seer in the Resting Grounds upgrades the nail after the Knight collects 1,800 Essence from Whispering Roots and Dream Bosses.

Godtuner and Godhome

Godtuner icon Per the wiki, the Godtuner is an automatic drop when the Godseeker is freed from the sarcophagus. The wiki describes it as "a device that resonates with beings of great power"; the icon appears under the health bar and blinks when a boss is killed that unlocks a pantheon position.

According to the wiki, the second interaction (Awoken Dream Nail on the sleeping Godseeker) is what actually opens Godhome. The Dream Nail strike loads the dream-realm pocket; every subsequent visit uses the Dream Gate or the Godhome bench for fast-travel back.

The wiki notes the Godtuner is what tracks the player’s Hall of Gods progress. Each boss has three difficulty tiers in the Hall (Attuned, Ascended, Radiant); the Godtuner glow indicates which tier was last cleared. The item has no in-run effect beyond the visible indicator.

Cast-Off Shell Secret Room

Per the wiki, Dream Nailing the Godseeker has a 2% chance of sending the Knight to the Cast-Off Shell, a one-time secret room. The room contains three statues, a single Geo pickup, and a hidden lore tablet about the Vessels; once the Knight leaves, the room cannot be re-entered.

According to the wiki, the Cast-Off Shell is one of the rarest content gates in the game. The 2% roll triggers on every Awoken Dream Nail strike against the sleeping Godseeker, so re-rolling is possible by entering and leaving Godhome on repeat attempts.

The wiki specifies that the room is "stored" inside the game but does not appear on any map. Speedrunners use the roll for entropy on completion category runs; standard players rarely see it.

Fluke Hermit and Nailsmith

Flukemarm icon Per the wiki, the Fluke Hermit is a small bug NPC living inside the Junk Pit. He calls the trash pile "Flukemarm’s treasure" and speaks reverently of the boss one room north. The Dream Nail dialogue confirms he sees the Flukes as his family.

According to the wiki, the Fluke Hermit drops no items and has no quest. His Dream Nail reading and the standard dialogue are pure lore content; the wiki documents him as the canonical link between the Flukes (water enemies), Flukemarm (boss), and the wider Junk Pit pile.

Nailsmith icon The wiki notes the Nailsmith corpse easter egg. If the Knight kills the Nailsmith in Dirtmouth (instead of sparing him for the Happy Couple Dream Boss path), his corpse appears in the Junk Pit pile near the shore. The body is unflagged and unmissable on a kill-route playthrough; the spare-route hides it.

Common Mistakes

  1. Trying to enter without Desolate Dive. Per the wiki, the breakable roof above the Junk Pit requires a downward-impact attack. Players who arrive with only Vengeful Spirit or nail swings cannot break the floor; Desolate Dive is the standard option.
  2. Burning the Simple Key on the City of Tears gate without restocking. According to the wiki, the City of Tears central-plaza gate also consumes a Simple Key. Players who use their only key there have to detour back to Dirtmouth for the Sly purchase before attempting the Junk Pit sarcophagus.
  3. Dream Nailing with the base Dream Nail. The wiki specifies the standard Dream Nail will not open the Godhome portal. The Seer Essence grind to 1,800 is mandatory; players who skip the Awoken upgrade see a dialogue line but no transition.
  4. Skipping Flukemarm while in the area. Per the wiki, Flukemarm sits in the room directly south of the Junk Pit entry. The boss drops Flukenest, a charm that transforms Vengeful Spirit into a 9-fluke spread; leaving without the pickup misses the cleanest spell-build swap for Mantis Lords and Watcher Knights.
  5. Missing the upward shortcut to the City of Tears. The wiki notes a breakable wall at the top of the Junk Pit chamber connects upward to the City of Tears, below the Nailsmith forge. Players who walk back through Flukemarm’s arena on every return burn extra time when the shortcut is a single nail break.
