Wonderland

It's a world similar to the Overworld, but with a variety of weird biomes, beautiful biomes, weird biomes, and chaotic biomes.
Most of these biomes are rarely found in the Overworld.
And unique mobs inhabit.
There are even more interesting dungeons.
To go to Wonderland, you have to find a rare "Wonderland Pit".
There is a special door directly below, from which you can reach Wonderland.
If you have any other good ideas, let us know in the comments.
Thank you for taking a look at my thoughts.
