About
Extended Caves expands underground exploration with generated caves, dungeons and cabins that can contain treasure pots holding random useful items; the cabins include jungle and cold-biome variants. Its cave decorations include six variants each of stalactites and stalagmites, pebbles, rock piles, limestone, lavastone and mosses, while cold-biome caves can contain patches of ice, packed ice and blue ice. Underground plants and mushrooms add both visual variety and practical effects: sweet mushrooms restore hunger when eaten or cooked, goldishrooms and shinyshrooms grant Haste, lumishrooms and fluoshrooms emit light, and frozen and fire moss slow or ignite mobs that enter them. Rare sealed crystals found on lavastone can be broken for effect crystals, which grant Speed, Fire Resistance or Regeneration when activated and can provide their effect again after recharging. The mod also adds biome-specific stones and decorations, including mud and mudstone in swamps, dirtstone in jungles, marlstone in savannahs and badlands, and slime bulbs that yield slime balls. Generation settings let players adjust or disable some structures and decorations, including mushroom group sizes.

Security
No harmful code found
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.14 to 1.16.5.
We checked its files and read their code, without running it.
What it can do on your computer
- Creates settings files
- The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file in your config folder.
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.3 latest files: the newest file for each Minecraft version and loader. None is for a recent Minecraft version, so the answer above is about all of them. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read without running it
- Looked for, not foundWe looked for these in the file and did not find them.The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.
Privacy
We found nothing it sends
It has no file for a recent Minecraft version. This is about its files for Minecraft 1.14 to 1.16.5.
We read its code without running it: it contacts no web address while you play.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of all 3 files, for Minecraft 1.14 to 1.16.5. See each file in Releases
AI
No sign so far that AI was used to make it
We looked for AI tools in its description, files and images and found none.
We have not read its changelogs yet.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.Not on Modrinth.
- Description and changelogsThe description, project page and newest changelogs: sentences saying an AI tool was used, and text pasted from an AI chat.Nothing found in the descriptionChangelogs not read yet
