Gelatinous Cube

Here is the PGS take on an RPG icon, the Gelatinous Cube. This aggressive omnivore is some kind of living thing from the Water Sphere. While it has no organs or even differentiation within its mass, it seems to have a simple animal like behavior, akin to a jellyfish. It can dissolve and digest any organic matter, leaving only the non-organic bits behind. Fortunately, it is very slow and is more of an ambush predator.
