Immune

Any living creature can be immune to the Spore Bounds infection. Almost all plants, for example, are immune. If an animal gets infected whilst being immune, they will end up transforming into a humanoid animal hybrid, instead of a horrific myconid creature. They retain sentience and sanity, and can speak quite well. It takes them a few days before acclimation to their body, and Florals will be extremely friendly and sociable to them, seeing the immune infected as one of them.
