Thought I'd post this now, I'm currently having some internet issues so the other polls and game news update will be up later this week.
Also I wanted to give a bit of context with what to expect with each character should it be chosen.
Princess Penelope- Most of her questline is already in the game but if she is chosen, I might look to expand it a bit, especially with the reaction from the royal family possibly finding out her secret.
Mrs. Tammy- School teacher in Royal City's trade district, should the player finish the questline for the crime lord, Tammy will notice that her pregnancy has significantly grown. Will include a bit more story and reactions from her students.
Watermelon Girl- Part of a questline associated with the new build coming soon. Should you restore the abandoned fertility temple, Aria will become a gardener for the mansion. She will help you raise various melon girl based plants which will result in some new consumables and recipes.
Dryad Guardian- Guardian's of the dryad village, you will have to go though out the temple dungeon and "save" them similar to the demon nursery. Afterwards once the dryads are rescued, there may be a fun interaction between them and the plant girls.
Tomb Mommy- You will encounter mummy's within the future pyramid dungeon, in this case it would be a very large and fertile tomb mommy.
