Goblin Cleanup The Forge Walkthrough: Fake Walls, Ice Slime & Notes

The Forge is one of the busiest levels in Goblin Cleanup's Dark Tower, and it hides two fake walls, an ice machine, and a pair of hidden notes that are easy to walk straight past. This Goblin Cleanup The Forge walkthrough breaks the route into short, repeatable steps so you always know which wall to touch next. A Goblin Cleanup The Forge walkthrough is only useful if it respects the level's order of operations — grab the lever first, and the rest of the route unlocks.

What the Forge Route Expects From You

The details below follow a player-written secret-area guide published on June 15, 2026, which covers the Dark Tower area by area and treats The Forge as a multi-step route rather than a single sweep. That author starts after the map's shortcuts have already been unlocked and opened, which matters: parts of the route only make sense once those shortcuts are live.

Two tools carry the whole route. A carryable lever sits at the end of an outside pathway and is required at the ice machine, and the ice machine turns your slime into an ice slime. That ice slime is the key that opens up the hidden notes. A Coordinator rune is a useful backup item if you want to escape the second note platform without dying.

Step-by-Step: Fake Wall #1 and the Lever

For this Goblin Cleanup The Forge walkthrough section, start at the room where the guide enters after the shortcuts are open. Head into the archway on the far left side of that room and take the stairs down. Partway down you will pass a Roof Trap.

• While descending, watch the right-hand side directly under the Roof Trap — a fake wall is tucked there.
• Walk through it to reach the upper pathway in the outside area near the beginning of the map.
• Follow that pathway to its end, where a lever is waiting.
• Pick the lever up and carry it to the portal where the map begins.

That lever is not optional flavor. It is the item the next section of this Goblin Cleanup The Forge walkthrough depends on, so if you set it down somewhere convenient and forget where, you will be doubling back.

Fake Wall #2, the Ice Machine, and Ice Slime

The guide labels this step "The Entrance – Fake Wall #2," but it belongs to the same Forge route. On the left-hand side of the area, look for a wall that seems slightly different from its neighbors: the baseboard is missing and the surface reads as a plain, blank wall. Walk straight through it.

At the end of that hidden hallway you will find an ice machine. Place the lever you carried over and activate the machine to access ice water, then use it to turn your slime into an ice slime. From here, this Goblin Cleanup The Forge walkthrough turns into an ice-slime route — both hidden notes assume you have made the transformation.

The Two Hidden Notes in The Forge

Hidden Note #1

Go back outside and look at the hill where the golden chest sits. There is an opening in the path leading up toward the chest. Cross over with the ice slime's icy trail and grab the note hanging on the wall.

One caveat, straight from the guide's author: as of that June 15, 2026 snapshot, the author reported that in Public v0.55.25 (the Dungeon Daddy Update) ice slimes no longer create a path on lava in this level. In that build, the author could not reach this note. If your version behaves the same way, this note may be locked until a patch restores the behavior — check the game's patch notes before assuming your route is wrong.

Hidden Note #2

The second note is essentially behind the golden chest. Climb up to the chest and take the small path on its right side, then follow it all the way up. From the top, look down: a platform waits below. Jump down to it and the second hidden note is there.

The catch is the exit. The guide notes you need the ice slime to escape that platform without dying. The alternative, per the same player experience, is to bring the Coordinator rune along and teleport back to the hub instead of trying to climb out.

Version Notes: What Changed in v0.55.25

Goblin Cleanup has been evolving, and that directly affects this Goblin Cleanup The Forge walkthrough. On a Steam Community discussion index captured on November 9, 2026, a pinned announcement on the game's official Steam page describes Goblin Cleanup as out now in Steam Early Access. Early Access builds shift, so treat every route detail — including the ice-slime behavior on lava — as a snapshot of the version the guide's author was playing.

The practical takeaway: if a step in this Goblin Cleanup The Forge walkthrough fails exactly as described, verify your build number first, then check the community secret-areas guide for updates. The same discussion index, captured on November 9, 2026, shows active threads about traps, runes, and challenge tuning, which tells you the community is still stress-testing the current build.

FAQ

Where is the first fake wall in a Goblin Cleanup The Forge walkthrough? Take the archway on the far left of the room the guide starts in, head down the stairs, and check the right-hand side directly under the Roof Trap. Walking through that wall drops you onto the upper outside pathway that leads to the lever.

Do you need the ice slime to finish The Forge? For the hidden notes, yes — according to the player-written guide, the ice slime is the tool used to cross toward the first note and to escape the platform below the second note. Without it, plan on the Coordinator rune teleport as your exit.

Can you still get the first hidden note after the v0.55.25 change? The guide's author reported that in Public v0.55.25 (the Dungeon Daddy Update), ice slimes no longer create a path on lava in this level, and the note was unreachable in that build. That is a June 15, 2026 observation, not a permanent verdict — check current patch notes.

Is there another way off the second note platform? Yes. Community reports describe bringing the Coordinator rune and teleporting back to the hub, which avoids the fall entirely. If you are working through this Goblin Cleanup The Forge walkthrough without an ice slime, that rune is your safety net.
