if you still have not found it its a slavery option when you get sold into slavery then you can bring the eggs back if you do it with the tentacle and give it to the doctor to make one that you get to keep in your cell
ah, okay, i was motly confused how with the slavery it was connected
How do you give it to the doctor?
When you push out the eggs they automatically go into your inventory and a new option shows up after talking to the doctor
