Hoe to get the Oil Drum
The Oil Drum is an extremely helpful item to gain since it holds 30 full servings of water. Plus it's simple to get thank goodness. Wait for a tsunami to strike, and then head to Beach 3 the following day (the beach near the jungle). Pick up everything on the beach you can find like seaweed, rocks, oysters, etc. You won't be able to hold everything there in your inventory, so continue to discard these items as you pick them up until there's nothing left on the beach. Now, go back into the Water Cave, go back to Beach 3 again, and the Oil Drum will be on the beach. TADA!

Wild Animals
Always dying while fighting an animal? Want a way to avoid dying entirely? In fact, do you want to avoid getting any damage at all?

When in fighting mode, continuously click the right button. Just keep on pressing it. The animal will jump at you but will miss because you keep on step-siding to the right. (or left -- just go in one direction constantly is the trick).

You need to hit the animal when it starts to go back into its resting position. Repeat the trick as many times as it takes to kill the animal. Using this trick you can actually kill an animal easily with just your fists!

Improve Partner's Cooking
Step 1: Go and gather carrots, roots, mushrooms, or anything else you find on the ground
Step 2: Give them to your partner to cook. Get some fish or meat to cook and eat alongside of her/his cooking
Step 3: Repeat steps 1 and 2 for about 10 days. You should see a remarkable inmprovement with cooking.

Remember, you won't fill yourself up of their burnt veggies! Get fish and eat those, as well! Using meat works, but it's generally a waste until partner gets better.
