Verified against the spelunky.ai port [v0.1.12](https://github.com/851-labs/spelunky/releases/tag/v0.1.12) on 28 October 2026. This page describes a secret. Jungle earth in the City of Gold is a quirk of Spelunky Classic in which the odd block of the City of Gold is the Jungle's earth rather than gold. | Quirk | | | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Status | GML + Oracle | | Where | [`scripts/scrRoomGen4.gml:317-322`](https://spelunky.ai/wiki/source/scripts/scrRoomGen4#L317-L322) | | Pinned by | `fidelity/replays/city-of-gold-seed-9.txt` | | Row | [docs/quirks.md §1, Bugs and leftovers in the 1.1 source](https://github.com/851-labs/spelunky/blob/main/docs/quirks.md#1-bugs-and-leftovers-in-the-11-source): “One block in a hundred of the City of Gold is the Jungle's earth.” | The [City of Gold](https://spelunky.ai/wiki/city-of-gold) is a [Temple](https://spelunky.ai/wiki/temple) level made of gold: its temple stone, its stone blocks and its push blocks all turn gold there. But the Temple's room script also makes the odd block of the [Jungle](https://spelunky.ai/wiki/jungle)'s earth, and the earth has no check for the City, so the City of Gold has a few blocks of plain green and brown earth among its gold. ## What happens The City of Gold loads with the player near its entrance. He walks right along its gold floor and over a block of the Jungle's mossy earth set in it[^1]. **Clip: Jungle earth in the City of Gold.** The City of Gold loads with the player near its entrance. He walks right along its gold floor and over a block of the Jungle's mossy earth set in it. ([video](https://spelunky.ai/wiki/media/clips/quirks/city-jungle-earth/clip.mp4)) ## Why The Temple's room script, which builds the City too, makes the Jungle's earth (`oLush`) for one of its always-solid tiles in a hundred, before it rolls a stone block or temple stone: ```gml scripts/scrRoomGen4.gml:317-322 if (tile == "1" and not collision_point(xpos, ypos, oSolid, 0, 0)) { if (rand(1,100) == 1) instance_create(xpos, ypos, oLush); else if (rand(1,10) == 1) instance_create(xpos, ypos, oBlock); else instance_create(xpos, ypos, oTemple); } ``` [`scripts/scrRoomGen4.gml:317-322`](https://spelunky.ai/wiki/source/scripts/scrRoomGen4#L317-L322), from `spelunky.gmk`, Spelunky Classic 1.1's source, © 2008, 2009 Derek Yu and Mossmouth, LLC ([Spelunky User License v1.1b](https://spelunky.ai/LICENSE.txt)). Its side room with two trees, which the City rolls among its side rooms, stands on a row of eight more[^2][^3][^4]. Temple stone turns gold in the City (`if (global.cityOfGold) sprite_index = sGTemple;`)[^5], and so do the stone and push blocks, but the earth's create event has no such line: it rolls a gold vein, a gem or an item as the Jungle's earth does[^6]. Broken, it gives rubble, and gold only from a vein[^7][^8]. It's harmless. ## Reproducing it Reach the City of Gold and look for green blocks among the gold; most Cities have some. The replay of the City with seed 9 loads it on frame 6745 with six earth blocks, one at (560, 96), near the entrance[^9]. The clip, cut from the run on to Olmec, walks over that one[^10]. [Reaching the City of Gold](https://spelunky.ai/wiki/city-of-gold-route) has the way there. ## In the port The spelunky.ai port reproduces it exactly: it's in docs/quirks.md's list of the 1.1 source's bugs[^8], and the oracle's fingerprint of the replay pins the earth blocks. No option turns it off. ## FAQ ### Why is there a green block in the City of Gold? It's a block of the [Jungle](https://spelunky.ai/wiki/jungle)'s earth. The [Temple](https://spelunky.ai/wiki/temple)'s levels make one now and then, and the [City of Gold](https://spelunky.ai/wiki/city-of-gold) is built as a Temple level. Its other blocks turn gold in the City, but the earth block has no such check, so it stays green and brown. ### Does the earth block in the City of Gold give gold? Only if it holds a gold vein, as the Jungle's earth sometimes does. Otherwise it breaks into rubble, where the City's gold blocks give gold chunks and a nugget. ### How common is the earth in the City of Gold? One in a hundred of the layouts' always-solid tiles, plus a row of eight under the side room with two trees, which the City rolls too. Most Cities have some: the one in the clip has six. ## See also - **Related:** [City of Gold](https://spelunky.ai/wiki/city-of-gold), [The Jungle](https://spelunky.ai/wiki/jungle), [The Temple](https://spelunky.ai/wiki/temple) ## References [^1]: Clip quirks/city-jungle-earth [^2]: [`scripts/scrRoomGen4.gml:70-74`](https://spelunky.ai/wiki/source/scripts/scrRoomGen4#L70-L74) [^3]: [`scripts/scrRoomGen4.gml:104-107`](https://spelunky.ai/wiki/source/scripts/scrRoomGen4#L104-L107) [^4]: [`scripts/scrRoomGen4.gml:505-508`](https://spelunky.ai/wiki/source/scripts/scrRoomGen4#L505-L508) [^5]: [`objects/oTemple/create.gml:7`](https://spelunky.ai/wiki/source/objects/oTemple/create#L7) [^6]: [`objects/oLush/create.gml:5-15`](https://spelunky.ai/wiki/source/objects/oLush/create#L5-L15) [^7]: [`objects/oLush/destroy.gml:3-33`](https://spelunky.ai/wiki/source/objects/oLush/destroy#L3-L33) [^8]: Quirk 1 (docs/quirks.md) [^9]: Replay `fidelity/replays/city-of-gold-seed-9.txt` [^10]: Replay `fidelity/replays/city-of-gold-seed-9-to-olmec.txt` ### Source code - [`scripts/scrRoomGen4.gml`](https://spelunky.ai/wiki/source/scripts/scrRoomGen4) - [`objects/oLush/create.gml`](https://spelunky.ai/wiki/source/objects/oLush/create) - [`objects/oLush/destroy.gml`](https://spelunky.ai/wiki/source/objects/oLush/destroy) - [`objects/oTemple/create.gml`](https://spelunky.ai/wiki/source/objects/oTemple/create)
