Lost in Blue: Shipwrecked! Cheats for Wii
If you want to prevent rats don't store your food on the shelf for too long. What you do is take the food off the shelf and place it back every two days and the rats won't appear.
The best way of killing your prey when you are hunting is to slowly walk up to it and when you are close enough use the spear or the knife.
This is best accomplished by eating the Sweetfish recipe for lunch (lunch is usually better than making a dinner).
When you have completed the game and saved when prompted Lucy will become a playable character when you start a new game session with your cleared saved game.
