to water plants: you need a coconut and sticks, go to mrs. wheeler and she'll ask for help, but you can then go to the Craft rock and look at question mark/or hatchet, and it will say you need a stick and a coconut, you can then fill water in a stream either by the food rock or in the second pond. you can get better hygeine in the second pond btw. after you go to the clear pond or streem, click on the water and fill water carrier, then go straight to mrs.wheeler, water teh banana tree near her shelter. do this a few times and then give mrs. wheeler a banana, then a chili pepper plant will grow near her, and you need to water that then give it the chef.
The puffer fish, even though it says that it can be caught at full yellow circle. i find that i have better luck in seeing it a few inches before it reaches there, like just when it gets clear. Area to find this is by the big rock, right before the crate that appears often. Pretty much where the person got stranded in, or at the end of the rocky area right after seeing the paint easel.and it's brown with athick head.
