Brazil is a verse that has 3 types of biomes.
These biomes are complexes of tunnels that sometimes have fake walls and if you go through these fake walls you are teleported somewhere else in the tunnel complex. These tunnels are mostly empty.
Completely empty areas that kill you if you enter them.
These things are a lot of wierdly shaped white objects as well as moving and rotating white objects all forming a giant structure area. This is where most HHs are.
Spontaneous Combustion Snake
This is a giant snake that hides behind an object and locks it’s eyes on something. A few seconds of having this lock eyes on you and you will spontaneously combust. This makes Brazil extremely dangerous as these things are everywhere.
