Black Goo

Black Goo is a semi-sentient slime like entity which often clings to the walls and floors of Level 29's unflooded sections. Its PH is 1.7, leading to skin contact with it being very dangerous. It is not capable of advanced movement as the fluid despite being sentient it is extremely viscous. It is avoidable especially if you have protective shoes or boots. 
== Behaviours ==
Due to the anatomy of Black Goo it lacks behaviour mostly. It is somewhat capable of movement and will occasionally flow towards humans or entities in order to consume them. It also seems to provide some kind of nutrition to Leeches as they often congregate around puddles of Black Goo.
== Biology ==
Black Goo mostly lacks biology and its interior is still highly enigmatic but it is most similar to liquid tar, albeit in a much colder state. It has some kind of "crust" on its outer membrane which is easy to cut through exposing more liquid. Samples have revealed that it is approximately 40% made up of hydrocarbons and 10% of many other known substances, mostly involving Hydrogen and Carbon. The other 50% is made up of a unknown substance.
== Discovery ==
Black goo was persumibly discovered around the same time that Level 29 was. The earliest found records of it come from the year 124 though.
