So far I only know Poisonous Mushrooms.
The Witch Princess isn't on Harvest Moon Another Wonderful Life, But she is on Harvest Moon D.S. and Harvest Moon D.S. Cute.
I know Harvest Moon DS Like: witch princess, harvest goddess...
You dont
If you want to make the Witch Princess happy say you are "fed up" with the Harvest Goddess.
Once you get married and have a child, they will be under the Witch Princess's picture on the Inhabitants List.
Your child! :)
In Harvest Moon DS Cute, your mother isn't a Character, she will not be mentioned of after the first event, (The event where you meet the Goddess and the Witch Princess)
If you are talking about rescuing her from the "other realm" that she was sent to by the Witch Princess, then all you have to do is rescue 60 of the 101 harvest sprites.
If you marry the Witch Princess your child with have silver/gray hair and yellow eyes.
NO! That's a weird question, but every one is curious about something...
As far as i know there is no code to marry the witch. But there is a code to increase her love for you. Check it out on codejunkies.com.
If you get her final Heart Event she will let you try a potion but there is no other time you get to have one.
