Change the bullet point beginning with “Egg Sack” in the “Anatomy” rule to:

Egg Sack: An egg sack may spend one of each nutrient listed in Nutrients to lay an egg cluster in the cell the creature is in, if that cell contains no neighbors that are not seaweed and the organ’s creature’s satisfaction level is Fulfilled. Its state is unfertilized, it has no fathers yet, its cell is the current cell, and its mother is the organ that laid it. Laying an egg cluster fulfills Procreation Drive.

Change the bullet point beginning with “Dart Sack” to:

Dart Sack: An organ in this state may, as a daily action, consume one nutrient to fertilize an egg cluster in the state of “unfertilized” that is in the same location as that organ’s creature if the organ’s creature’s satisfaction level is Fulfilled. No organ may fertilize an egg cluster of which it is the mother. When an organ fertilizes an egg cluster, that organ’s name is added as a father to that egg cluster. Fertilizing an egg cluster fulfills Procreation Drive.
