Cobblemon: Underground expands Minecraft's underground exploration with new tunnel networks, hidden caves, valuable resources, Pokémon encounters, and special discoveries.
Inspired by the Underground from Pokémon Diamond, Pearl, and Platinum, the mod brings a new reason to explore beneath the surface.
And the best part? Everything generates in the Overworld. No additional dimension required!
Underground Tunnel Networks
The mod introduces underground structures of different sizes, ranging from tiny tunnels to massive interconnected networks.
Each structure offers something different:
- Tiny Structures – Small tunnel systems with a few rooms and discoveries.
- Small & Medium Structures – Larger networks with branching paths, additional chambers, and more opportunities to explore.
- Large Structures – Massive underground networks featuring multiple tunnels, hidden areas, and special locations.
Not every tunnel leads somewhere important, but you never know what you might discover around the next corner!
Different Underground Environments
Not every underground area looks the same!
Different biomes can feature their own underground environments, with variations in tunnels, caves, resources, and Pokémon habitats.
Hidden Rooms & Secret Areas
Some discoveries are easy to find. Others require a little more effort or luck.
Underground networks can contain:
- Rooms connected directly to the tunnels
- Hidden chambers behind mineable walls
- Pokemon with Hidden Ability's
- Higher Shiny Rate's
Sometimes the most interesting things are hidden right behind a wall!
Ores, Fossils & Excavation
Exploration isn't just about finding new tunnels.
Underground structures are designed to contain valuable resources, including:
- Ore veins embedded in tunnel walls
- Evolution Stone ores
- Excavation blocks containing fossils and other discoveries
- Resources hidden throughout the underground
Whether you're searching for fossils, mining resources, or simply exploring, there's always a reason to keep digging.
Pokémon Encounters
These tunnels aren't supposed to be empty!
Different underground environments are designed to support wild Pokémon encounters, with Pokémon suited to their surroundings.
Alpha Pokémon Nests
Some of the rarest underground locations contain something particularly dangerous: Alpha Pokémon!
Special chambers can serve as nests for powerful Alpha Pokémon, guarding valuable discoveries.
But don't worry! Alpha Pokémon aren't supposed to block every tunnel or ordinary cave.
Most underground areas can be explored freely. Alpha encounters are reserved for particularly rare and special locations.
Vanilla-Like Exploration
One of our main goals is to keep everything feeling like a natural part of Minecraft.
You don't need to enter a new dimension or follow a complicated progression system.
Just grab your pickaxe, explore the underground, discover unusual tunnels, and see where they lead!
Cobblemon: Underground is still in development. Features are being implemented, tested, and improved, so their availability may vary between versions.
!!!! BUGS !!!!:
-the New Watertunnem entrance is blocked.
THE STORY:
The idea for Cobblemon: Underground actually started during a conversation while we were playing Minecraft together.
At some point, we asked ourselves: Why hasn't anyone really changed underground exploration?
Sure, there are already some amazing structure mods out there, but we wanted something a little different. Something that makes normal, vanilla-like exploration more exciting and rewarding.
Imagine you're just mining for resources when suddenly you discover a strange tunnel that looks nothing like the usual Minecraft caves.
You decide to explore it and find hidden rooms, fossils, rare ores, Pokémon habitats, or maybe even an Alpha Pokémon!
That's exactly what we wanted to create.
Over the following days, we kept discussing new ideas. What if different biomes had their own underground environments? What if there were small tunnel systems, massive underground networks, hidden treasures, and special places waiting to be discovered?
One idea led to another, and eventually Cobblemon: Underground became a real project.
About Development
Just like my other projects, this mod is developed with the help of AI, mainly OpenAI Codex.
The ideas and concepts come from us. We test everything on our own computers, explore the generated structures, find problems, make adjustments, and continuously improve the mod.
We're not professional mod developers. We're simply Minecraft and Cobblemon players who wanted to bring an idea to life.
And since we're already making it, why not share it with everyone else?
I hope you enjoy exploring the underground as much as we enjoy creating it!
Future Plans:
We still have plenty of ideas for Cobblemon: Underground!
Our goal is to keep expanding underground exploration with more environments, discoveries, and challenges while maintaining a vanilla-like Minecraft experience.
Here are some things we're maybe planning for future updates:
- More Underground Biomes – New tunnel environments with blocks, decorations, and Pokémon habitats.
- More Structure Variations – Additional tunnel layouts, larger networks, and rare underground locations.
- Expand into the Nether - Tunnel in the Nether
- More Hidden Rooms – Secret chambers, buried treasures, and special areas that reward curious players.
- Rare Resources – Additional Evolution Stone deposits or special ore veins.
- Better Mod Compatibility – Improved integration with Cobblemon addons, world-generation mods, and modpacks.
- More Customization – Additional configuration options for structure generation, rarity, encounters, and rewards.
Community Suggestions
We're always open to new ideas!
If you have suggestions for new underground environments, structures, Pokémon encounters, or other features, feel free to share them in the comments.
We're developing this mod for fun, and we'd love to see what other players would like to discover underground.
Please remember: These are plans and ideas, not guaranteed features. Some may change or never make it into the final mod.
