What must I do to defeat the Werefox and obtain his treasure???
My boy! From my fasting experience, I can tell you that what you need are proteins, the basis of your body's cells! They'll build and repair your body tissues if you get injured, and they form your hair, skin and nails.
The proteins get broken down into amino acids. They are chemical building blocks that help your body with many processes such as building muscle and maintaining immune function.
To get these amino acids you'll need to eat food that is high in protein. Grains, vegetables, and nuts have incomplete proteins, which only have some of the amino acids you'll need, but foods with complete proteins, like poultry, fish, and eggs, will give you all of them.
Remeber my advice, young one, and I wish you good luck in your battle against the Werefox. I hear he has a protein-filled diet as well, heh heh.
