d100 Flesh pits of the space gods pt2: lifeforms

Thank you for d100 suggestions - mounts and doom of kingdom have done well and will do some variants of in future.

Bio-dungeon systems might adapt readily producing new strains or mimicking things it has contacted or developing a strain with resistances or a new environment.

You might want to add magic or psionic abilities too depending on the setting (1in6 if available)
