Homunculus Creation is a bit more involved.
1: Finish all outstanding tasks for the library.
2: Read Homunculus Creation.
3: Create Allure Potion. An option to add Greenthorn Bark appears in the list. Do it, and fill bottles with "Alluring Base."
4. Create Homunculus Stone. Create 4 to save time.
5. Go to pit (a speech bubble should be next to the option).
6. Create potions, then dump them into the pit. Do this until options appear in the pit.
7. Repeat until you create all four Homuncuties.
8. Enable automation for free resource collection.
9. Visit each of the four areas and look for the option to see what your girls are up to for the scenes.
Note: Each homuncutie has four images, three of which are in their respective areas. I suspect the dev will add a new homuncutie for each new area in future updates.
