Add a new rule called “The Adoption Games”:

If at any time there exists a Medusa or Egg Cluster whose Mother is Idle or not an Organ, any Organ that has fertilized that Medusa or Egg Cluser may attempt to adopt it and become its Mother.

To do so, the Organ must make a Story Post with a title of ‘[Organ] wants to adopt [number]’ where [Organ] is replaced with their name, and [number] is the number of the egg cluster or Medusa they wish to adopt.
The Story Post body must include a heart warming story about the relationship between the Organ and the Medusa or egg cluster.
If at least 3 other Organs make a comment on that post that indicate unambiguous support for the adoption, then the Adoption is successful and the Organ who made the post is the new Mother.

Once an Organ has created a post to attempt an adoption, that Organ cannot attempt any other adoptions for the next 48 hours.
