Try not to use the ring or steal your neighbors stuff. All of which drops your humanity. The second main boss you actually have to fight is in a cave that you have to bust some rocks out of the way to get in.
I wasted all my ammo and then realized I had a note in my inventory that was from the guy who sang the tree to sleep(read basic strategy 2). OK here's what to do.
Use your dagger only and you will have to hit him about 4 times before he disappears in the dirt. Do this sequence a few times and then Froto will say he needs help. Then read the letter by pressing the black button when you have it pulled up in your right inv. window.,, boss beaten. For extra goodies try to get the chest open that is sitting up on the ramp BEFORE you read the letter.
