Minecraft has a total of three dimensions that you can explore: Overworld, Nether, and End. Each one of them has unique biomes, blocks, mobs, and terrain generation. For years, Mojang has stuck with these three dimensions and has not added a fourth one. Since Minecraft Java Edition can be heavily modified, the community has come up with all kinds of third-party features, including entirely new dimensions.
One such mod that adds a brand new dimension is called The Undergarden. Here is everything to know about the Minecraft mod.

What does the Undergarden mod offer?
The Undergarden is a mysterious and dangerous dimension that supposedly exists below the bedrock layer of the Overworld. It is filled with brand-new biomes, vegetation, blocks, and creatures, giving you loads of new features to explore.
Though it is said to be located underneath the bedrock layer of the Overworld, it is accessed through a unique portal that can be built anywhere, just like a Nether portal. The portal frames must be built using stone or deepslate bricks, and they can be lit using a new item called a catalyst, made from four iron ingots, four gold ingots, and one diamond.
Once players enter the new dimension, they can spawn in any one of the 15 new biomes. These will mostly have a dark and dingy feel to them since they all generate underneath the bedrock layer, which is even deeper than the deepslate stone area. The flora in these biomes has gradually adapted to grow without the need for light or oxygen. Hence, players can also face tough challenges in some biomes as they will have limited breath.
When it comes to mobs, this mod offers various passive and hostile critters. Some of these passive creatures are Gwib, Thrallid, Smogspitter, Flourishing Bushbaby, etc. Meanwhile, some hostile monsters are Rotwalker, Dweller, Mog, Nargoyles, Gloomper, etc.
The Undergarden mod also adds some massive boss mobs like The Forgotton One, Inky Maw, and Stoneborn.
