what a title
anyway haha, I had a baby creature with 2 wings and when it had 1 gem, it was able to fly at full distance instead of just the normal 1 tile around it. I don't remember if it could pick up berries, clear grass, etc.
In version 1.1.0, if a mother gives birth to twins and the mother moves out of the nest first, the twins both go to the center of the nest and clip together.
