How to Enter The Undergarden
To enter the underground world, you must first create a Catalyst. The crafting recipe is shown below:

After creating the Catalyst, build a portal frame in the shape of a Nether portal using Stone Bricks or Deepslate Bricks. Activate the portal to The Undergarden by right-clicking the inner bottom part of the frame while holding the Catalyst.

You can also use bricks obtained in The Undergarden itself to create the portal.
