Roamel

Roamel is a gelatinous, pink plant-like substance that covers many of Fathom's plains. It has a similar ecological position to grass, leeching nutrients from the soil and using photosynthesis for energy.

Characteristics
Roamel is a gelatinous semi-solid that maintains its shape unless subjected to significant outside force or other pressures. It is both heliotropic and geotropic, reaching toward the sun while making an attempt to stay close to the ground. Roamel will not climb up structures or dangle freely, as it does not have the structural stability to do so. The most common movement of roamel is an action called a 'cascade,' in which a mass of roamel consumes and buries a small object caught within it, so as to achieve maximum surface area for photosynthesis.

Most living organisms are far too large for roamel to be a real threat, but small insects, children's toys, scraps of food, and other such things that could fit in one's hand can be lost to the roamel, likely to never be found again under the gel. Given sufficient time, roamel is also capable of consuming larger objects over a long period, such as corpses, tools, or wagon wheels, provided they are laid flat against the ground.

Behavior
Roamel reproduces in a similar manner to baker's yeast, budding and rapidly duplicating itself. As a result, a field of roamel is effectively made of an innumerable count of tiny organisms.
