Hey, no, you have to defeat the giant snake, and you'll get its meat directly. That's the meat you need to give to that hungry samurai. Save the other ones for when you need to fully heal yourself.
Thank you Xeif! I didn't see your response on time. Maybe for the better. I found the snake and killed it (btw awesome mechanics for the boss fight - well done!). Got the rope, got the paddle/oar and move to the end. I won't put the password here, as it will ruin all the fun for the others.
