Notes on the Mimicry Marcus creature.
Official Transcript
This creature is actually composed of countless leeches that have merged together to imitate the late Dr. James Marcus. The leeches secrete an adhesive bodily fluid over their cuticle in order to mold together. This coating hardens as they fuse together.
When in the presence of prey or a threat, the leeches will break their form and attack. They are a revolting, but powerful enemy.
