The goo is a semi-intelligent gelatinous organism that co-exists symbiotically with its host creatures. It inhabits the host's internal structure, replacing essentially all internal organs and systems, serving as muscle, bone, respitory, nervous, and digestive systems. This process is painless and feels more like a tickle than organs melting due to their being replaced by a mass of goo. While in the host it grows to optimal mass, which expresses itself as a swollen, pregnant appearing belly. For ease of transmission to other creatures, the goo prefer female or hermaphodite hosts, if the goo infects a male, the male developes female characteristics, a female-ish body structure, breasts, and turning their penis into a dual purpose ovipositor(. The goo spreads primarily by crystaline eggs filled with immature goo, generated inside the body.The eggs themself are made out of waste materials the body has stored up to create the hardened and smooth blue crystals eliminating the need to use the restroom. These eggs are laid via a retractable extension of the labial walls, functioning as an ovipositor. The goo also has teh ability to encase anything inside the hosts belly in an eggshell and expell it when the host sees fit. To support the increased weight and mass of the expanded belly, the host's legs become shorter and more muscular, growing a dragon-like tail if they lack one to serve as a weighted balance for the forward place weight of the belly. A creature with an existing tail ha their tail alter into a heavier draconic state, to serve the same function, though this transformation doesn't always happen. The goo is very malliable and is capible of forming and retaining shapes, external from the body. Common uses of this include extending a long 'tongue' or goo, forming a penis, or enlargening one's existing maleness. Above all this is a volenteered symbyote and if the host refuses the symbyote will die within the egg that was implanted into the host otherwise the host and symbyote will live peacefully together.
