• Plant Witchberry Seeds

That young'un over there,, is going to grow up to be a heck of a farmer some day. I can tell just by lookin' at him.

I think I'll plant him some witchberries. Kids love witchberries - it'll be a nice surprise.

You will receive:

The trick to a good witchberry crop is to wait until they're nice and sweet.

It's not as easy as it sounds. I remember when I was a just a [sic] cub, puckerin' on some not-even-half-ripe witchberries because I couldn't wait like Grandpa told me to.

Alright, witchberries! I can't wait!

But I'm gonna have to.
