That non-Newtonian Ooze everyone's been talking about.

Oozeblek are Oozes that through methods unknown have taken on the properties of non-Newtonian fluids.

I am have put together a Bestiary entry for the Oozeblek, my interpretation of the non-Newtonian Ooze everyone has been talking about. I have also included an optional game rule that I believe to be a fun addition to the game and has an interaction with this new ooze.
